Overview
Features labelled with an asterisk (*) are only available for
FishHunter 3D.
FishHunter 3D/PRO is a powerful sh nder created for
Apple and Android phones and tablets. The sonar oats on
the surface of the water where it tracks water temperature,
water depth, bottom contour and sh locations. FishHunter
transducers can be casted from a bank or dock as well as
trolled behind your boat or used for ice shing.
The FishHunter 3D/PRO wireless sh nder sonar connects
to your smartphone/tablet via Wi-Fi using our free software
app, so you don’t need to have a cell tower connection or use
your cellular data to use your new sh nder.
Using our free FishHunter software app, you will also have
the ability to access and store critical shing information like
your favorite shing spots, your catch details and share your
information with your friends and other anglers.

Charging
1. Locate the 3 pin charging port on
the bottom of the sonar. It is on the
opposite side from the tow point at the
back of the sonar
2. Push the USB cord into the bottom of
the sonar so that it is in snugly. You
must slide the charge cord past the
transducer on the bottom of the sonar
which makes it slightly dicult to get
the charge cord into the side of the
unit. This is the correct way to ensure a
good connection with your sonar.
3. Plug the USB cord into USB charger. A
red light will appear on the top of the
sonar and stay on until fully charged.
Connecting
1. Download theFishHunter app from the Google play store
or iOS app store.
2. Create an account by opening the app and following the
steps on the screen. Be sure to do this before you leave

|11
Overview | FishHunter 3D/PRO Operator Manual
your coverage area.
3. Ensure you have charged your FishHunter for minimum
of 4 hours before rst usage.
4. Attach your FishHunter to the braided line on the end
of your shing line or tether it to the red leash that was
provided in your box. Tether it by threading the red leash
through the tow point on the front of your FishHunter
or by attaching the line tying clip onto the front of your
sonar and the end of the red leash provided.
5. Drop the FishHunter into the water.
6. The sonar will automatically turn on when placed in
water and will begin slowly ashing red from the top of
the sonar. If you don’t see any lights then the FishHunter
is not charged.
7. Open your Wi-Fi settings on your smartphone or tablet.
Refresh the list and select FishHunter Wi-Fi XXX.
¼Note: It may take up to 1 minute to appear.
8. Wait for your phone/tablet to tell you that you are
connected to FishHunter Wi-Fi. You will see a check mark
on your Wi-Fi settings to show you are connected.
¼Note: Other phones or tablets can cause connection
errors. Ensure their Wi-Fi settings are turned o.
9. Once connected, open theFishHunter app and go to the
Sonar section.

12 | Overview | FishHunter 3D/PRO Operator Manual
10. If you are connected to your FishHunter correctly, you
will see the following options:
• Directional Casting*
• Bottom Mapping*
• 3D Contour*
• Bathymetric Mapping*
• Ice Fishing Flasher
• Switch Device
11. The slow red ashing light on your sonar will start
ashing quickly when connected and sending
information to your phone or tablet.
The unit will automatically power down and turn o when not
in the water after a few minutes. If the lights remain on after it
is removed from water, ensure the charging pins are free from
any water or debris by blowing on them. Additionally, you can
insert and remove the charging cord and that should enable
the sonar to power down after 60 seconds. If the unit still
remains on, then double check that your wi is turned o and
repeat the above.
You can reset your sonar at any time by inserting the charge
cord into the bottom of the unit and removing it.
Wi-Fi connectivity and FishHunter
In order for you to get the best possible signal and connection
with your FishHunter, we recommend that you follow the
instructions below.

|13
Overview | FishHunter 3D/PRO Operator Manual

looking down towards the sonar and should be elevated
above the oating sonar.
Best practices:
1. Line of sight.
2. Good elevation.
3. No obstructions.

Side menu options
Shallow water mode
This option will adjust the scale on your screen to be between
0.4 m - 4.5 m (1.4 ft - 15 ft) and adjust the settings to give you
the best results when in less than 4.5 m (15 ft) of water.
¼Note: You must adjust the power slider. Failure to adjust
the power slider can result in the FishHunter giving you
incorrect bottom values.
Auto range
The screen will take a few seconds to nd the depth for the
area and adjust its settings automatically to balance the gain
and pulse width of your sonar to give you the best results.
Every time you cast the FishHunter into the water the screen
will take a few seconds to nd the depth for the area that you
are shing in. In order to optimize your experience, use the
auto ranging function that automatically balances your sonar
to give you the best possible results at each depth you are
shing in.
¼Note: In most cases leaving it in Auto is the best way to
use your sonar.
If you are taking your FishHunter in and out of the water
repeatedly, like when casting, we suggest that you try
manually setting the depth range to increase the speed of

|19
Menus and settings | FishHunter 3D/PRO Operator Manual
your FishHunter. You can set the depth manually from the side
menu. The side menu changes slightly depending on what
view you have the sonar in when you open the menu.
Select the depth
You can manually select the depth you would like to operate
in. This will improve the speed in nding bottom.
Surface Filter Slider/Ice Thickness Slider
Whenever you use a sh nder, you will get what is called
surface reverb or surface noise as the sound waves from the
transducer reach the surface of the water.
The Surface Filter allows you to customize how much of
the area on the surface you would like your FishHunter to
ignore or include to give you the most accurate sh detection
possible.
The lter is set to the center position by default each time
you turn on the sonar, but as you adjust the slider from left to
right a number appears on the right hand side of the slider.
This number is the actual amount of the surface that will not
be measured by your FishHunter. In very calm conditions, you
can set the Surface Filter to a very low number to allow you
to search for sh that are located very close to the surface.
In more extreme conditions where you have high wind, high
waves or when you are trolling your FishHunter behind a boat
motor, you will want to turn Up the Surface Filter.

20 | Menus and settings | FishHunter 3D/PRO Operator Manual
Try to set the Surface Filter to a number that matches where
you see the surface noise stop in the Raw data view on your
screen.
In the example below, you would set the top sonar to 2 m (6.5
ft) and the bottom sonar to 0.5 m (1.5 ft) to give you the best
results.
