BASIC OPERATION:
Switching the Readings from English to Metric
1. Remove the battery holder as per the instructions in the
“Installing the Batteries” section.
2. While looking into the battery compartment, use a small
screwdriver, or other slender object, to reach into the battery
compartment and move the switch to the LEFT for Metric
readings, or to the RIGHT for English readings.
3. Replace the batteries as per the instructions in the “Installing
the Batteries” section.
Switch
Obtaining Depth Readings (Depth Reading Mode)
1. Place the sonar sensor side of the device into the water.
Make sure to hold the device perpendicular to the water
surface.
2. Press and Release the activation button.
3. The current water depth will be indicated on the display:
•
The depth will continue to update 4 times per
second while the device is left in water that is
between 2.5 and 200 ft deep (.8 and 61 m).
•
If the device is unable to obtain an accurate
depth reading or if it is removed from the water
“- - -” will be displayed.
4. The device will turn off automatically after being removed
from the water.
Water Surface
NOTICE:
The device will not obtain readings through air. You CANNOT stand
on the deck of your vessel and obtain readings unless the device is
in direct contact with the water or you use one of the techniques
described within this manual.
Obtaining Fish Readings (Fish Finder Mode)
1. If a fish is detected while in the Depth Reading Mode, a fish
icon will illuminate on the display.
2. A blinking fish icon may represent the presence of a school
of fish moving though the sonar beam.
Obtaining Temperature Readings (Thermometer Mode)
The H22PX has an integrated temperature sensor built into the
sonar sensor housing.
To Obtain Temperature Readings:
Temperature
Sensor
1. Activate the Depth Reading Mode.
2. While in Depth Reading Mode, press and release the
activation button.”
3. The display will show the current temperature.
•
To obtain air temperature readings, hold the device in your hand and
activate the Thermometer Mode as per the above instructions.
•
To obtain water temperature readings, place the Temperature 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).
SHOOTING THROUGH A BOAT HULL
The H22PX advanced sonar capabilities allow it to “Shoot-
1.
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.
2
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
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.

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
sounder/fish finder to search for drop-offs and hiding fish under docks,
weeds, or vegetation.
To Side-Scan:
1. Activate the Depth Reading feature.
2. Place the device perpendicular to the water surface to obtain a
correct depth reading.
3. Once a correct reading is obtained, move the H22PX around in a
scanning motion (similar to using a flashlight).
NOTICE:
To obtain depth readings during side scanning the sonar signals
must be directed at a solid surface that is within 200 ft (61 m) to
function properly. You must be certain to aim the device at an
object or the bottom within this range.
USING FOR DIVING
The H22PX is waterproof to 200 ft (61 m), allowing you to use it as a
range finder or target finder for snorkeling or diving. Keep in mind that
the sonar signals must be directed at a solid surface that is within 200 ft
(61 m) to display depth readings.
•
You must be certain to aim the Device at an object or
the bottom within this range.
•
ALWAYS be certain to attach the Wrist/Safety Strap to your person, as
the device will float to the surface if released.

Nothing Happens When I Turn the Power On
Make sure that you have installed a good set of batteries and aligned them as per thhe
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 sset
from a newly opened package.
The Depth Reading Is “---”
Make sure that the sonar sensor is in direct contact with the water and that you are
operating the unit in depths between 2.5 and 199 ft (.8 to 61 m). Be aware that the deppth
signal is sent from the sonar sensor in a manner similar to that of flashlight beam. Holdinng
the unit perpendicular to the water surface will ensure accurate readings. The unit will not

function properly if there is air between the sonar sensor and the water surface; keep this
in mind when using the device through a boat hull or ice.
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
2.5 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 sonar will mistake it
for fish. Trash & debris may also give false readings.
