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

SHOOTING THROUGH A BOAT HULL
The H22PX 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 H22PX 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
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.
