Sensor into the water and activate the Thermometer Mode.
INFORMATION:
This device has a temperature accuracy rating of plus or minus 5%.
The temperature probe may take up to 90 seconds to adjust to
extreme changes in temperature. If you desire to have instant
temperature readings you may want to consider purchasing the
NorCross® Infrared Marine Thermometer (IR101SP).
OBTAINING DEPTH READINGS THROUGH A BOAT HULL
The H22FX advanced sonar capabilities allow it to “Shoot-Thru”
the bottom of a boat, canoe, kayak, etc.
The hull must be made out of solid fiberglass, or a
maximum of 1/8” (3.1 mm) aluminum, and be in
direct contact with the water, with no air pockets.
The device will not work through wood, plastic, or
any composite material.
To “Shoot-Thru” the Hull of a Boat, Do One of the Following:
1. Place the transducer in .5 inches (13 mm) of water
against the hull bottom.
2. Coat the face of the transducer with petroleum jelly and
press it against the hull bottom with a twisting motion.
3. Place the transducer in a plastic bag that is full of water
and place against the hull bottom.
4. Refer to our website for more advanced instructions.

NOTICE:
Some boats have a hollow space between the floor and the
hull bottom called a bilge. The H22FX will not “Shoot-Thru” in
this type of boat unless it is placed directly against the hull
surface that is in direct contact with the water.
“SHOOTING THROUGH”ICE
IMPORTANT:
This unit may be used for ice fishing, but special attention must
be paid to not allow the unit to freeze to the ice, as removal
may cause damage to the LED light housing.
This device has advanced sonar capabilities also allow it to obtain depth and fish reading
through solid ice. You MUST use special techniques to obtain readings through ice:
NOTICE:
The ice must be smooth and free from excessive air.
Air will show up as white imperfections inside the ice.
The ice must be black in color.
To Shoot Thru Ice:
1. Clear away snow to expose the ice surface.
2. Place a small amount of liquid water on the ice and set
the transducer side of the device on the water.
3. If there are any air pockets between the device and
ice, or the water below the ice, the device will not work
properly and will require you to try another spot, or cut
a hole in the ice to use.
INFORMATION:
You can also use the “Plastic Bag” and “Petroleum Jelly” instructions in
the “Shooting Thru a Boat Hull” section for shooting through ice. Visit
our website for additional suggestions.
SCANNING FOR DEPTH CHANGES OR FISH (SIDE-SCAN)
The device has the ability to be used as a sideways scanning sonar depth
finder/fish finder to search for drop-offs and hiding fish under docks, weeds, or
vegetation.

Nothing Happens When I Turn the Power On
Make sure that you have installed a good set of batteries and aligned them as
per the diagram within the battery compartment. You may also need to test the
batteries in another device to ensure they are charged. If in doubt, replace the
batteries with a set from a newly opened package.
I See Fish Under the Sonar Sensor, but Nothing Appears on the Display
As with the depth reading, the fish finder will not detect any objects that are
closer than 1.5 ft from the sonar sensor. If you’re fishing in water that is less than
3 feet deep, it is recommended to discontinue use of the fish finder.
The Depth Reading is Incorrect
Make sure that you are pointing the sonar sensor perpendicular to the water
when trying to obtain depth readings.
Extremely heavy vegetation may confuse the sonar of the fish finder causing it to
misinterpret the depth. If you are certain that the readings are incorrect under
these conditions, discontinue use.
I’m Not Getting A Reading While Trying to Shoot Through My Boat Hull or
Ice
Shooting through the hull of a boat/canoe or ice can be difficult, as hidden air
pockets will prevent you from obtaining a reading. Make certain that the hull or
ice is solid from the surface to the water with no air bubbles and/or gaps.
Shooting through composite hulls (plastic) or cloudy ice is not possible as tiny air
bubbles are usually present in these situations.
I’m Getting False Fish Indications
The most common cause of false fish indications is extremely tall weed growth.
If weeds grow taller than 50% of the total water depth in a particular area, the

w w w . h a w k e y e e l e c t r o n i c s . c o m
sonar will mistake it for fish. Trash & debris may also give false readings.
Adjusting the sensitivity setting to the lowest level may reduce these false
readings, but if they do not go away, it is suggested that you discontinue use of
the fish finder under these conditions.
