1 About sens07vest
1.1 Overview
The sens07vest is an electronic floating device to return free diver
and spear fisher back to the surface in case of danger.
sens07vest constantly monitors drowning risk based on user pro-
grammed settings and inflates automatically a floating bladder in
case of high drowning risk.
The blackout protection feature requires a manual confirmation
from the diver after the dive in order to prevent inflation of the
bladder.
The sens07vest is designed to protect free divers and spear fisher
up to 50 meters under water when using a 95gr CO2cylinder. Be-
low this depth the buoyancy might not be enough due to the high
water pressure.
User Manual sens07vest
May 2020 Page 5
1.2 sens07vest components
The core component of the sens07vest is the sens07inflator which
is the electronic inflator module. The sens07inflator can be config-
urated for a large field of professional water activities such as
spear fishing, free diving but also for swimming, surfing,
kitesurfing, etc. by using the sens07app.

User Manual sens07vest
Page 6 May 2020
1.3 sens07 inflator components
The sens07inflator consists of 4 components:
1. The inflator head contains the electronics, the sensors, the
red/green light indicators, the battery, the optical light sensor
to configure sens07 by using any smartphone and the self-test
button.
2. The actuator module gives the thrust to pierce the CO2cylinder
and opens the gas flow in order to inflate the rescue bladder.
The actuator module needs to be replaced after every inflation.
3. The base unit connects the sens07 head, actuator module and
CO2cylinder to the inflatable bladder. The base unit is equipped
with the manual emergency handle which allows manual infla-
tion of the bladder at any time.
4. CO2cylinder (60gr. or 95gr.) with 1/2-inch thread providing the
needed gas volume to inflate the bladders up to 50 meter
depth. It is important to verify that a fresh and unused CO2cyl-
inder is inserted before each dive.
User Manual sens07vest
May 2020 Page 7
1.4 Activation on water contact
The sens07 inflator immediately
starts its auto-supervision when wa-
ter can be “sensed” by the integrated
contact-free water sensors. When
taking out of the water, the sens07
inflator automatically goes into a
power-saving “ready” mode.
The sens07 inflator deliberately has no "power" button - it is al-
ways switched on, even if it is stored for months or years; activa-
tion cannot be forgotten.
However, it is possible to enable manual deactivation of the sens07
inflator for security reason like in aircrafts.
Please note that switching off the sens07 inflator doesn’t save en-
ergy and is not recommended by ProVitaTec.
1.5 No battery to change or replace
Battery change or battery charge is not required
during the lifetime of the sens07 inflator due to
ultra-low energy consumption. The life-time of a
sens07 inflator is at least 5 years, the full life-
time depending on user activity.
In the unlikely event that battery power should run low due to very
extensive usage, the red LED will light up when pressing the self-
test button.

User Manual sens07vest
Page 8 May 2020
1.6 Interactive self-test
Pressing the sens07 button will initiate a
self-test and give a clear and intuitive feed-
back confirming the proper function of the
sens07 inflator by showing the green light.
The self-test checks battery status, all sensors and the microcom-
puter as well as the presence of a fresh and correctly inserted ac-
tuator module.
Please note that a manual CO2cylinder check is required.
1.7 Suspend upcoming inflation in water
A suspend button allows the user to
delay upcoming inflation for a
pre-defined time. The suspend feature
can be enabled and configured by the
sens07 app.
User Manual sens07vest
May 2020 Page 9
1.8 Customization using the sens07 app
The inflation parameters and features (called
profile) can be customized using the sens07 app
and are wirelessly transferred to the sens07
head.
The sens07 head can store up to 3 profiles for
different sport or dive activities.
Switching between these pre-stored profiles is
done by the user holding the sens07 button for
2 seconds.
The smartphone is not required to operate the sens07vest or to
switch between the already uploaded profiles.
1.9 Data recording (optional)
The sens07 head is able to constantly
log all sensor data for week, moths or
even years, depending on the activity
of the user. The recorded data is
stored in a non-volatile memory which
allows data restoration even in case of
severe physical damage of the sens07
head or embedded electronics.

2 sens07 inflator manual
2.1 Switching between profiles
Pressing the button in dry condition for more than 2 seconds will
switch to the next profile specified in the sens07 app. A successful
change of the profile number is confirmed by a short flash of both
LEDs ( green and red), followed by the profile number which is
identical to the self-test:
• 0 flash: Manual mode (off)
• 1 flash: Profile 1
• 2 flashes: Profile 2
• 3 flashes: Profile 3
Note: Please verify configuration using the sens07 app in case you
can’t change the profile as expected.
User Manual sens07vest
May 2020 Page 11
2.2 Suspend upcoming inflation while diving
Pressing the self-test button when the sens07vest is submerged
will suspend (freeze) the risk inflation countdown for the specified
suspend time. This time can be defined by the sens07 app.
The suspend button works under water only. An active suspension
will be cleared when reaching the Safe Zone.
The suspend button doesn’t influence the blackout countdown.
This feature can be enabled or disabled using the sens07 app. When
disabled, pressing the button will have no effect underwater.
2.3 Manual inflation handle
Pulling the manual inflation handle will inflate the bladder in any
situation (emergency).
The manual inflation handle is an emergency device and works
without any electronic, configuration or actuator module.

User Manual sens07vest
Page 12 May 2020
2.4 Replacing actuator module & CO2 cylinder
The actuator module needs to be replaced after each inflation.
Disassembly of the sens07 inflator
1 Remove CO2cylinder by firmly rotating cylinder counter clock-
wise.
2 Remove sens07 head by rotating rippled screw nut counter
clockwise.
3 Remove actuator module from the sens07 head and discard.
Rearming of the sens07 inflator
1 Check the date (month & year) of the sens07 head. The date
should not be over today’s date.
2 Insert a new and unused actuator module into the sens07
head.
3 Install the sens07 head by screwing rippled screw nut clock-
wise until it meets the housing shoulder.
4 Install an unused CO2cylinder by rotating clockwise into base
unit until CO2cylinder is secured firmly.
Perform the self-test as described after replacing the actuator
module.

3 LED signals
The inflator head has 2 front LED for important information and 3
back LED for system information.
3.1 Main LEDs on the front side
The green and red front LED signal the following information:
3.1.1 Water zone indicator
A short blink every second indicates water detection. The number
of blinks corresponds to the dive zone.
The red LED is used instead of the green LED in case of a negative
self-test. However, the sens07 inflator will still try to operate as
expected, but there is a high chance of failure.
The water zone indicator can be disabled for defense applications.
3.1.2 Suspend Mode
An alternating green & red LED blink means that the button was
pressed under water suspending inflation for a certain time.

3.1.3 Blackout warning
After emersion in Blackout-mode, sens07 blinks fast with both LEDs
indicating the need for immediate user action (press the button to con-
firm consciousness).
3.1.4 Inflation occurred
A simultaneous blink of the green & red LED together every second
means that inflation was triggered and sens07 is waiting for total
emersion. Replacement of the actuator module and CO2cylinder is
needed.
3.1.5 Timed Inflation: Active
A green light every 10 seconds indicates a running Timed Inflation
counter. Inflation will be triggered as soon as timed inflation runs
out.
Note: Timed inflation can be stopped by holding the button.
3.1.6 Timed Inflation: Standby
A green double light every 10 seconds indicates that the sens07 in-
flator is in standby waiting for water contact which will start the
Timed Inflation count-down.
Note: This standby mode can be stopped by holding the self-test
button.

flator, visible through the transparent housing. They offer more
detailed system information when pressing the self-test button.
They are not needed for normal operation.
3.2.1 Green LED: Inflation reason report
The amount of flashes of the green LED indicates the reason of the
previous automatic inflation. The inflation reason report is perma-
nently stored and can be read out each time when pressing the but-
ton. The inflation reason report is cleared when inserting a fresh
actuator module.

4 sens07-app
4.1 Introduction
The sens07-app allows to manage up to 3 profiles defining the way
how sens07vest is operating. The profiles are transferred wireless
using flickering light flashes from the smartphone screen which are
received by the sens07inflator light sensor.
After profile transfer the sens07vest works completely autono-
mously. The sens07 app is not needed for operation.
User Manual sens07vest
May 2020 Page 17
4.2 Installation and registration
The sens07 app is free of charge, available for IOS and for Android
devices and can be downloaded and installed in the usual way from
the Apple App store or Android Play store.
A registration code for private or cooperate users is required before
using the sens07app.
• Private user:
Enter your name and Email which will return a password by
Email. Use your email and password to log-in.
• Corporate user:

4.3 Tab 1: “Profiles”
The sens07 app can manage up to 3 very different profiles defining
the way how sen07vest is operating.
This screen shows the 3 profiles including profile number (1 to 3),
title and short description.
The button “Reorder” on the upper right corner adds a “handler” to
each profile, allowing to move the profile up or down.
Clicking on the profile name goes to the profile configurator.
The last segment shows the actual profile switch mode defining
profile switching when holding the self-test button.
The button “start transfer” launches the process to transfer the
profiles to the sens07 inflator.
User Manual sens07vest
May 2020 Page 19
4.3.1 Profiles configurator (basic)
The drowning algorithm is based on 3 depth zones:
Safe zone, Diving zone and Inflation zone.
A simple inflation countdown starts at the
specified value when entering into the Div-
ing Zone. Inflation is triggered when infla-
tion countdown reaches zero.
This inflation countdown freezes when re-
turning into the Safe Zone. Staying in the
Safe Zone for the specified time resets the
countdown to the initial start value.
Entering into the Inflation zone will immedi-
ately inflate.
Pressing the Suspend Button under water
will freeze the countdown for the specified
time (Inflation Delay). This feature is op-
tional and is activated by the slider “Enable
Suspend Button”.
Combat diver can disable the LED Signal un-
der water for this specific profile.
The last segment Profile Info offers to
name the profile and to add any kind of free
description for better understanding.
Save changes before returning to the main
menu.

User Manual sens07vest
Page 20 May 2020
4.3.2 Profiles configurator (Blackout)
The profile of type "Blackout" requires manual confirmation of con-
sciousness after the dive within a specified time.
The drowning algorithm is based on 4 depth zones:
Safe zone, Diving zone, Warning zone and Inflation zone:
The diving countdown starts at the specified
value when entering into the Diving Zone. In-
flation is triggered when the diving count-
down reaches zero. In a later system revi-
sion, the Warning Zone will offer additional
features, but at the moment there is no dif-
ference to the Diving Zone.
Pressing the Suspend Button under water
will freeze the inflation countdown for the
specified time (Inflation Delay). This feature
is optional and is activated by the slider “En-
able Suspend Button”.
Blackout Countdown starts to count down
when returning to Safe Zone after being at
least 10 seconds in the Diving Zone.
Upcoming inflation can only be stopped by
pressing the button.
Combat diver can disable the LED Signal un-
der water for this specific profile.
The last segment Profile Info offers to name
the profile and to add any kind of free de-
scription for better understanding.
Save changes before returning to the main menu.
PS: Depending on your sens07 app licence an “Advanced” button is
shown which offers more detailed profile configuration.

4.3.3 Profile switcher
Clicking on this segment offers the choice of different profile
switching plans which will be applied when holding the sens07in-
flator button for 2 seconds.
Some of them include the manual mode (off) to deactivate auto-
matic inflation. The manual handle will always inflate the
sen07vest.
Note: Manual mode is only needed for special legal requirements.
We strongly recommend to stay always in automatic mode (don’t
even include the OFF feature into the profile switching plan). Power
consumption is not reduced in manual mode.

4.3.4 Start transfer
Taping on the Start Transfer button offers the following options:
• Sound support indicates the start and end of a transfer process
with an acoustic signal.
• The transferred profile can be protected by using a password.
The entered and transferred a password, then the next transfer
will also require the same password. A wrong or missing pass-
word on the next transfer will ignore the transfer and indicate
the rejection by a red blinking LED. Deactivating password pro-
tection is done by sending the valid password but disabling the
password switch.
Transferring the profiles to the sens07 inflator
1. Click on “Start transfer” and place the phone on the inflator
front side (touch the sens07 inflator with the display).
2. Wait 10 sec. or listen to the sound support (if activated).
3. After transfer check for the blinking green LED confirming suc-
cessful data transfer.
4. Confirm seeing the green LEDs by clicking “Yes” on the app.
5. Click on “Retry” in case of no blinking LED signal which will re-
launches optical data transfer (don’t forget to press the self-
test button on the sens07 inflator again).

Ensuring identical profile data in the app and sens07 inflator
The sens07 app can’t read out data from the inflator head. There-
fore it is important that you confirm a successful parameter trans-
fer on the sens07 app. This ensures that the parameters stored on
the app and stored on the sens07 inflator are identical.
Any parameter change on the sens07 app will be market with the
waring text “Profile changed since last transfer” informing you that
the profile parameters on the app and on the sens07 inflator are
not identical anymore.
This waring text will be cleared on the next successful data trans-
fer.

4.4 Tab 2: “Timer” (optional)
The second tab offers timed inflation or inflation countdown, inde-
pendent of the sens07 sensors.
Timed inflation can be programmed up to 4 months in advance by
selecting date and time. A slider allows to cancel timed inflation
when pressing the self-test button.
Inflation countdown allows to specify the number of weeks, days,
hours, minutes and seconds until inflation. There are 3 sliders for
additional options:
• The countdown start after transfer or on first water contact.
• Countdown aborts when sens07 is taken out of the water.
• Countdown aborts when pressing the self-test button.

5 Check before and after diving
The following points must be checked before each dive
5.1 Verify CO2cylinder
Unscrew the CO2cylinder and verify that there is
no visible piercing hole (see upper CO2cylinder in
the picture).
After checking make sure that the O-Ring in the
base unit is still on its position.
Screw the CO2cylinder firmly onto the base unit.
The sens07vest uses a standard CO2cylinder
with a 1/2-inch thread.
5.2 Check sens07vest components
The sens07vest consists of different me-
chanical components which needs to be
checked before starting a dive:
• Bladder: Verify the bladder for any hole or other kind of dam-
age. It is recommended to inflate the bladder every 2 years to
check it for holes.
• Straps: Verify if the straps are well sewed and the buckles are
not damaged.
• Rubber parts: Check if the rubber parts are not broken or brit-
tle.
User Manual sens07vest
May 2020 Page 27
5.3 Choosing the right CO2 cylinder & max. depth
The uplift of the sens07vest decreases with depth (see graphic)
and the negative buoyancy of the diver increases due to the wetsuit
compression and excessive weights.
Therefore there is a point where sens07vest can’t bring the diver
back to the surface anymore.
We recommend a maximal depth of 30m when using a 60gr. CO2
cylinder or a maximal depth of 50m when using a 95 gr. CO2cylin-
der in order to get at least 8 kg uplift performance.

User Manual sens07vest
Page 28 May 2020
5.4 Perform Self-Test
Pressing the button in dry condition (outside of the water) will
launch the self-test which is confirmed immediately by the green
or red light.
The red LED indicates an internal problem such as actuator module
not inserted or already used, battery low, sensor error or other in-
ternal errors. In most cases, the problem is based on an already
used or wrongly-placed actuator module that needs to be re-
placed.
Note: The CO2cylinder is excluded from the self-test!
The amount of blink (green or red) indicate the active mode or pro-
file:
• 0 flash: Manual mode (off)
• 1 flash: Profile 1
• 2 flashes: Profile 2
• 3 flashes: Profile 3
• 4 flashes: Timed inflation (option)
Note: In case of a negative self-test (red LED), the sens07 inflator
will still do it’s best to function as usual. However, there is a high
chance of failure and you must not use sens07vest.
User Manual sens07vest
May 2020 Page 29
5.5 Location of the manual handle
Make sure that the manual cord is accessible from outside and that
the cord runs directly without any diversion to the sens07 base.
The cord is equipped with a Velcro tag near to the red handle. This
Velcro tag must be attached to the Velcro closure on the
sens07vest, so that the handle is always available on the same,
specified position.
It is very important that you can feel and find the handle immedi-
ately because you don’t have time to search for it in case of emer-
gency!
5.6 Put on the sens07vest correctly
Take care that the 2 metal buckles on the side are adjusted cor-
rectly. Don’t pull them too tight so that you can breathe freely.
Never forget to attach the crotch strap! The uplift of the bladder in
case of inflation is about 15 kg.
Without the crotch strap the sens07vest may lift over your head,
which may be very dangerous!
5.7 Rinse sens07vest after diving
The sens07vest needs similar maintenance like most scuba dive
equipment. Please rinse the sens07vest in freshwater. Make sure
that the water gets into the vest by opening the lower right part of
the zipper. It is important that the sens07 inflator and CO2cylinders
are cleaned from saltwater to avoid corrosion.

6 Configuration examples
The following examples illustrate the configuration options.
6.1 Inflation due to exceeded diving time
Entering into the diving zone launches the inflation countdown
starting from 2 minutes. The diver returns to the water surface
within the 2 minutes and stays in the safe zone for 1 minute, which
resets the inflator countdown, ready for the next dive.
The second dive exceeds the maximal time of 2 minutes which trig-
gers inflation and brings the diver back to the water surface.
Note: Staying less than 1 minute in the safe zone will not reset the
inflation countdown and just continue counting down when return-
ing to the diving zone.

6.3 Blackout protection
Entering into the diving zone launches the inflation countdown (3
minutes).
The diving and warning zone do not yet offer any functional differ-
ences, except that they can be recognized by different flashing se-
quences on the sens07 head.
The Blackout countdown is launched as soon as the diver is back in
the safe zone and triggers inflation in case the self-test button is
not pressed in time (15 seconds).
There is no other option to stop upcoming inflation except getting
out of the water in time. Please note that the water sensor needs
some seconds to detect missing water.
After pressing the button (confirming no blackout) the sens07vest
is ready for the next dive.

7 Advanced explanations &trouble shooting
7.1 Unsuccessful optical data transfer
A successful optical data transfer is indicated by a blinking green
light after the transfer. The red light or no light at all indicates an
unsuccessful optical data transfer, which may have the following
causes:
• Display is too far away from the inflator head.
We recommend to touch the sensor head with the display of
the phone to protect the light receiver of the sensor head as
good as possible from light inferences.
• The optical data transfer is robust against ambient light (for ex-
ample bright sunlight). However, neon tubes and LED lighting
can emit pulsating light that is invisible to the human eye but
can interfere with optical data transmission.
• Additional display protection or waterproof sleeves for your
mobile phone may interfere with the optical data transfer. In
case of problems, please try If problems occur, please try to
transfer the data without the protective cover.
• The sens07 app will set the display brightness to 100% before
data transfer. Please check that, as the sens07 app cannot con-
trol the brightness on all Android phones.

7.2 Unsuccessful self-test
An unsuccessful self-test will not stop the sens07 inflator to per-
form its normal operation as far technically possible. All features
(like LED signals, drowning risk calculation, optical data transfer,
blackout protection and even firing the activator module for infla-
tion) are still enabled and performed as far as possible.
An unsuccessful self-test has the following 2 effects:
1. The water zone indicator (see 3.1.1) and self-test are using
the red LED instead of the green LED
2. A malfunction at any stage must be expected.
7.3 Testing the sens07 inflator without the vest
The configuration of the inflator head can be tested without the
vest, CO2cylinder, base unit and actuator module. Just immerse
the inflator head into water and observe the LED for “water zone
indicator”and “inflation occurred” signal in order to better under-
stand the effect of your configuration.
7.4 Accuracy of the pressure sensor (depth)
The installed pressure sensor is very accurate. However, you may
notice a difference when you compare the depth with your dive
computer. These deviations have the following causes:
1. Depending on the arm position the dive computer may be up to
1 meter away from the sens07 inflator head (sensor).
2. The electronics need about 2 seconds to charge the ignition en-
ergy. Therefore the set depth may already be exceeded.
3. The depth calculation is based on fresh water. Saltwater is
about 3% heavier, which can lead to slight deviations.
