How do I Use Sonar for Ice Fishing?
Ice fishing can require a lot of guesswork. With a sonar system, however, you can take the guesswork out of ice fishing and track the whereabouts of large game fish. Sonar technology provides detailed statistical data about the underwater activities of game fish. The sound waves set off by the sonar device collide with the frequency given off by a fish to provide a view of the fish's exact location. Using sonar technology, you can find the best location for your ice fishing hole and drop your line to the best depth for a strike.


Difficulty: Easy

Things You’ll Need:
  • Ice fishing drill
Step 1
Buy a sonar system that is appropriate for ice fishing. Most manufacturers design sonar systems specifically for one type of fishing application, such as open-water fishing or ice fishing.
Step 2
Power on the sonar device, as directed by the owner's manual. Check the LCD or TV screen for a signal.
Step 3
Brush off snow until the ice where you are planning to drill is completely exposed. Set up the transponder according to the manufacturer's instructions. Set it directly on the ice so the sonar device can search for fish and provide a read-out of the water below. An initial read-out will indicate if fish are present.
Step 4
Drill a fishing hole if fish are plentiful in the area.
Step 5
Lower the transponder into the water. Adjust the gain control, which is a mechanism used to manipulate color presentation on the flasher display.
Step 6
Check the graph or flasher for a read-out. Expect to receive information related to fish activity below the surface of the water, as well as a pictorial or graphic representation of their depth and size.

Tips & Warnings

Most sonar systems provide instructional videos. All provide instructional manuals and customer service support.
Solar systems are equipped with a lowering cable.
