GPS AND MAPPING
The built in GPS-receiver and a 5-position numeric ID-attribute allow you to tag important data with coordinates with a simple
key press. Your data is stored on a built in SSD drive and are immediately available to you when connecting the GEO standard
USB 2.0 interface to any PC or Apple computer. No software installation or drivers are needed, and your field data can be
opened straight in your favorite GIS- or spreadsheet application without any special converting software.
Complex operations such as area measurement, 3D mapping of targets and trail mapping have integrated functions in the GEO
instruments. These functions are available without any external tools. The 3D Vector function allows you to measure horizontal
targets such as canopy width or height of piles or heaps.
FORESTRY
The VERTEX LASER GEO model is especially suitable for forestry measurement applications. The use of an ultrasonic transponder
helps you to quickly and accurately determine if a tree is in or out a circular sample plot. The ultrasound method is superior
compared to alternative methods, as it can be used in dense forests and areas with thick understory.
HEIGHTS
Standard height measuring functions with laser (VERTEX LASER GEO: also ultrasound) such as 3-point, 2-point or 1 point
measuring are available in the easy-to-follow menu system. The non-magnification red dot sight helps you to easier identify
individual targets such as tree tops in the forest.
UPGRADES AND CUSTOMIZATIONS
Firmware in the GEO instruments can be upgraded by the user. New features are available for you to purchase and implement
as soon as they are ready & released. Alternative firmware’s for user specified utilization standard applications can be offered at
development and license costs.
COMMUNICATION AND ENERGY
The built-in Bluetooth V4, Low Energy transceiver, enables long range wireless data transfer to your favorite handheld device.
The GEO instruments have built-in, long-lasting Li-Ion battery that are charged with mini USB interface.

TRANSPONDER T3
A transponder T3 is (normally) included in the VERTEX LASER GEO instrument system.
The transponder is equipped with an ultrasonic transmitter and a receiver that communicates with the measuring instrument.
The transponder can be used both for aimed/direct measuring and for circular measuring, with the 360-degree adapter. To use
the transponder to measure tree heights, remove it from the adapter/spreader and pin it to the tree stem at preset height.
The T3 Transponder is equipped with a beep signal, indicating ON or OFF status. The T3 has no switch and the VERTEX LASER
GEO instrument is basically used as a remote control to turn off and on. When turned on, the Transponder stays active until
turned off or after approximately 20 minutes of inactivity.
The transponder uses one alkaline 1,5-volt AA battery to operate, which is placed under the battery lid.
1. Transponder housing
2. Ultrasound transceiver
3. Battery cover
360 ADAPTER/SPREADER
An adapter/spreader and a custom plot center staff can also be used in the
Vertex Laser system. The adapter allows the ultrasound signals to spread in a full
360-degree circle for circular sample plot work.
MONOPOD PLOT CENTER STAFF
The custom plot center staff or monopod is used
together with the adapter for the transponder. This
solution enables the user to measure in 360 degrees
around the monopod, using ultrasound. The
monopod is telescopic, light weight and can be
height adjusted.
MONOPOD
Another optional accessory is a monopod, suitable when measuring thin objects and to obtain a steadier aim. The GEO
instruments mount to the monopod with 1/4-20 mount. If using a monopod with the GEO instrument, it is important to use a
non-magnetic monopod. If using a regular monopod staff, you will run the risk of compromising the compass in the GEO
instrument. Read more under the Compass section, this user guide.

FUNCTIONS AND USE OF THE BUTTONS
BUTTONS
The GEO instrument’s overlay contains three buttons: two arrow buttons and the ON
button.
ON
One press at the ON button starts the GEO instrument. The ON button is used to select a menu command or a function; to
confirm a selection or a value; and as a trigger when heights and inclination are measured. When you use the laser function to
measure distances, the ON button can be kept pressed down to activate a scanning function. The laser will scan continuously
until a target is obtained or the button is released. The scanning function is especially useful to measure thin objects such as
power or phone lines.
ARROW BUTTONS
Use the arrow buttons - DME and SEND - to scroll between menus, and to change values and selections.
DME BUTTON
When the instrument is turned off, the ultrasonic distance measuring function can be activated by pressing the DME button.
The DME button is also used to work with the Laser. Press the DME key to temporarily change the preset Laser mode (First-,
Strongest-, Last- target), to allow the laser sensor to work in best possible mode for the situation. Example: use mode Last to
avoid the laser to hit a target in front of your main target such as grass or bushes.
SEND BUTTON
With the SEND button, data can be sent with IR and Bluetooth to an external device or saved in the internal memory while
measuring. Data transfer via IR or Bluetooth is disabled when data storage is enabled.
EXIT (DME + SEND)
Press both DME and SEND buttons at the same time to step out of a menu, to interrupt a function or to turn the instrument off.
The instrument has automatic turn off function that is activated after approximately 2 minutes of inactivity.
RESET
If the software in the instrument is locked, a reset can be done by pressing all keys (DME, SEND and ON).
TURN OFF
The instrument turns off after 2 minutes of inactivity. To turn off the instrument manually, press the DME- and SEND buttons at
the same time (Exit) when in the main menu. If GPS or Bluetooth is activated, the instrument will hold 18 minutes before
completing turn off. This is to keep GPS or Bluetooth active and ready for new measurements within the time frame of 18
minutes.

SIGHT
RED DOT SIGHT
The GEO instruments have a highly intensive red dot
sight. The sight has no magnification, to simplify
identification of close-by objects.
HEADS-UP DISPLAY
The sight also works as a heads-up display where various
results are presented. More details are shown on the large LCD display on the left side of the instrument.
BATTERY AND CHARGING OF BATTERY
The instrument has built-in Li-Ion battery. The display shows a
battery symbol with battery status in four (4) steps (100%, 75%, 50%,
0%). Charging of battery is made by connecting the mini USB cable to
the Mini USB interface contact at the back of the instrument.
When the battery is full, charging stops automatically. The
instrument should not be turned off during charging. If the battery is
empty, a full charge takes approx. 3.5 hours, and a fully charged
battery will last for approx. 2000 measuring operations. Change of
battery, if needed, can only be done by authorized service stations.

SETTINGS
In the SETTINGS menu, all settings are made to measure heights, distances and angles.
1. Press ON to activate the GEO instrument.
2. Select SETTINGS and press ON to confirm. Choose SETTINGS in the SET menu and press ON.
3. Use the DME or SEND button to change values and settings. Press ON to step to the next field. Settings are saved when you
have stepped through all fields. To quit, press the DME- and SEND buttons at the same time.
METRIC/FEET:
Select if to use metric or feet for heights and distances.
DEG/GRAD/%:
Select unit for inclination/angles as DEG (degrees 0…360), GRAD (grades 0…400) or % (percentage).
P.OFFSET:
The Pivot offset refers to the distance from the front of the instrument to an
imagined point where the extension of the aiming line from the tree and the
top of the tree coincide.
The point is located behind the neck of the instrument operator. The Pivot
offset should in normal cases be set to approx. 0,3m/1.0ft.
Since the Instrument will presume that the distance to an object is right under
the required height of the target, half of the diameter value should be added
to the Pivot offset to compensate for the tapering of a tree. When measuring tree heights, it is recommended to add half of the
mean diameter in the stand/area where you are currently measuring.
TRP.HGT:
The height of the transponder or other point of reference should be equal to the distance from the ground level
to the point of reference. In normal cases, the TRP.HGT refers to the center of the transponder T3 or zero (0)
when the point of reference is equal to ground level or the lowest part of the measurement object. In menu
HEIGHT DME, the TRP.HGT is always added to the height. The normal height value for the T3 transponder is
1.3m/4.3ft = breast height.

Vertex Laser Geo and Laser Geo User Guide ENGLISH 2021-02-02
©Haglöf Sweden 12
EYE HGT:
The value for EYE HGT is equal to the eye height of the operator from ground level. This value is used in the 1-point
laser function to calculate the total height from ground level.
M.DIST:
In the HEIGHT DME menu, a manually measured and input distance can be used where the distance to the object is known, for
example a fixed distance between poles. M.DIST can also be used if you experience problems to measure distances with
ultrasound and/or laser, for example if a large object is blocking the object to measure. Note! The accuracy of a manually
measured and input distance affects the accuracy of the height result. Remember to set the correct transponder height TRP.HGT
since this value is also used when using a manually input distance value, see above.
LASER MODE:
Set if the laser is to react to the first object (FIRST) it hits; the object that gives the strongest
signal (STRONGEST) or react to and
measure the last target it hits when
you measure distances (LAST).
You can temporarily switch the
laser mode by pressing the DME
button, and toggle between LAST-,
FIRST- and STRONGEST target. Note that the laser will go back to default mode after one measurement.
BAF:
BAF is used in the DME menu and normally to measure a distance with ultrasound (VERTEX LASER
GEO). The BAF function is also available when working with laser. When performing a “relascopic”
measurement operation, the built-in BAF function can be used to control the minimum tree
diameter ‘Ø’for a plot. When working with relascope or prisms, some trees in the plot can be
difficult to see and to determine if to include the tree in the plot or not. By measuring the
distance from the plot center, the Instrument can calculate a minimum diameter for the tree to
be included in the plot. Built-in BAF factors are: 0.5, 1, 2, 3, 4, 5, 6, 7, 8, 9 (m2/ha), alt. 5, 10, 15,
20, 25, 30, 35, 40, 45, 50 (ft2/acre). Use the option ‘- -‘ to disable the BAF function.
In leaning (inclining) terrain, the VERTEX LASER GEO can compensate for the inclination and
calculate the diameter measure. In such cases, use the ANGLE function in the menu to measure
the distance and angle from the tree to the reference point (see section ANGLE in this user’s
guide).

COMPASS
Select if the compass should be used in the height functions. Turning off the compass makes the
height measurement go faster. The compass will always be used in functions that requires it or if
both the GPS and Memory are activated.
MAGNETIC DECLINATION:
Set the local magnetic declination -90.0°-+90.0°.
The magnetic declination in the Instrument is factory set to 0.0. Before using the GEO
instrument, you may need to enter a magnetic declination for your geographic area. The
declination correction is (only) important if your data will be used in a GIS software or if true
north azimuth is required.
The Earth is surrounded by a magnetic field, and any unobstructed magnetized object, or North-seeking compass, will orient
itself with the magnetic North and South Poles. Magnetic declination (also known as magnetic variation) is the difference in the
bearing, or angle, from your position to true North (also known as the North Pole) and magnetic North, which is located
somewhere in Northern Canada. The magnetic declination varies significantly from location to location in the world and slightly
also from year to year. It is important to find out the correct magnetic declination for your area to ensure that the calculations
your Instrument performs are correct.
Choose the SETTINGS menu to set current declination for the position you are at, between true north and magnetic north. The
Instrument will automatically adjust the measured compass angle with the set declination. A declination between -90.0° and
+90.0° can be set and obtained.
1. Press ON to start the GEO instrument.
2. Select SETTINGS and press ON to confirm selection. Then choose SETTINGS in the SET menu and press ON.
3. Press ON, step by step, until MAGNET. DECL is shown.
4. Use the DME- or SEND button to change the sign (‘+’/’-‘), then press ON to step to next position.
5. Use the DME- or SEND button to change digit at current position (‘+’/’-‘). Press ON to go to next position.
6. Repeat step 5 above until all digits are defined.

DISTANCE MEASURING
For the LASER GEO instrument model, descriptions for the laser method are valid.
There are two methods to measure distances in the VERTEX LASER GEO: laser or ultrasound. Which method to use for a field
operation is determined by factors such as terrain composition and understory. Current weather conditions can also be of
importance. The laser function is often used to measure heights and to measure long distances in open terrain.
In combination with the T3 transponder, ultrasound measuring can be used when working in circular sample plots and to
measure short distances in dense terrain/forests.
DISTANCE MEASURING METHODS
LASER
Laser can be used to measure the distance to targets such as trees, power lines or buildings. Laser can also be used to work with
the BAF function, although the ultrasound method (VERTEX LASER GEO) is more commonly used for this application.
The instrument laser sensor is of optimal quality and offer accurate results and extensive measuring range. The laser emits
invisible, eye safe infrared energy pulses that reflect off the selected target back to its optical receiver. The distance is calculated
by comparing the return time to the speed-of-light constant and presented in the instrument display. The ability of a laser
sensor to measure to a target depends on the target’s reflectance and any interference between the sensor and the target, such
as dust, fog, foliage or other. Reflectance is determined by color, opacity, distance and the reflection angle as well as the density
of any ambient interference between the sensor and the target. A lighter target is more reflective than a darker one and thick
dust will reduce the signal strength more than light dust. An adjustable laser filter allows for flexible measuring, where you can
select to measure the closest object, the farthest object or the object that submits the strongest signal.
Use the DME button to temporarily change the preset Laser mode (First-, Strongest-, Last- target) allowing the laser to work with
the best possible mode for the situation. Example: Use Last mode to avoid that the laser sensor hits a target in front of your
main target such as grass or bushes.
ULTRASOUND
Vertex Laser Geo: Together with the T3 transponder, ultrasound can be used to measure the distance to a plot center and to
obtain sample plot radius. You can work with the BAF Basal Area Function to determine if a tree is to be included in a sample
plot study. Ultrasound can be used in dense forests; a big advantage compared to other methods.
The Vertex ultrasound method uses ultrasonic signals to obtain a distance reading from the measuring instrument to the T3
transponder. The height is calculated trigonometrically with the measured results on distance and angle. The T3 Transponder
works both in a 60° mode for direct height measuring, for example pinned on a tree stem; or in a 360° mode when mounted
onto the monopod plot staff –great when working in circular sample plots with the Vertex Laser Geo ultrasound method.
Ultrasound technology can be used when the target is completely or partially covered and hard to visualize. The methodology is
useful in circular sample plots, and if the reference point (plot center) is covered by understory such as shrubs and bushes.
When measuring the angle to the reference point, the horizontal distance can be calculated.
Working with factor gauges or prisms can be difficult in areas with heavy underbrush, and poor sighting can prevent a correct
diameter evaluation. With the instrument built-in BAF function (Basal Area Function), the minimum tree diameter for trees to be
included in the plot can be featured, by measuring the distance from the tree to the reference point/plot center.

HEIGHT DME –2-POINT MEASURING WITH MANUAL DISTANCE
1. Press ON to activate the instrument.
2. Select HEIGHT DME and press ON to confirm your selection.
3. Accept the distance value shown in the display (M.DIST) with a short press on the SEND button.
If this value is incorrect, it can be changed in the SETTINGS menu. M.DIST refers to the distance
between the eye height and the point of reference.
4. Aim at the point of reference at a known height, TRP.HGT in menu SETTINGS, set to zero (0) if the point of reference is
equal to ground level. Press ON to measure the angle to the point of reference. Keep pressing the ON button until a
short beep goes off and a result is shown in the heads-up display. Release the ON button.
5. Aim at the top (or other height you wish to measure) on the object and keep pressing ON until a short beep goes off
and a result is shown in the heads-up display. Release the ON button.
6. The height (TRP.HGT included) is featured in the display.
a. SD Slope Distance (m or feet)

MAP TRAIL
The MAP TRAIL function will enable you to collect target coordinates in a logical sequence by using either the laser or the
ultrasound method, pitch and azimuth data. The MAP Trail function is useful when mapping different pathways, possible tracks
or roads where GPS data is not accurate enough or when mapping for a cableway system in the forest to haul out logs. If the
forest is dense, the ultrasonic method can be used to measure distances.
The instrument’s built-in compass shows direction continuously in the display before
completing a measurement routine. This function guides the user to hit a target in the
desired direction.
Normally, your last target will be your next reference. However, a reference can be moved
with the built-in GPS or by using the laser or DME. This is used for example when the next
target is not visible from your reference point, and you must move away from the trail to
be able to see it.
1. Starting point
Enter a 5 position ID for your
trail; Ex: 12345.
Use laser to measure to the
first target.
A GPS coordinate will be
stored with this starting
point (if GPS option is
enabled).
Go to the target.
2. Use laser to measure to
the second target.
Go to the target.
3. If your next target is not
visible from the trail, move
to a position where this
target is visible and use the
GPS to store your position.
Use laser to measure to the
third target.
Go to the target.
4. Use laser to measure to
your fourth and last target.
Your target data is now
stored in a CSV- and a KML-
file.
