WU-206: Simple, Reliable Technology - Part 1

by Cody Roswick & Dave Truett

An angler can use a Flasher both in the boat and also on the ice. The angler must also learn to evaluate bottom structure quickly, and record these slight variations shown on the flasher. Remember, the one bad thing about a flasher is that signals are shown instantaneously, unlike those shown on sonar graphs. Therefore, if you’re not constantly looking, you may miss seeing the screen for a second as the boat is moving.

The flasher is one of three sonar devices that walleye anglers can use today. The other two sonar devices are: liquid-crystal (LCD) recorders and video graphs. All three devices operate on the same principle. The transducer, attached to the boat’s hull or motor, must be functioning properly in order for the Flasher to respond.

The 1240A Dual Range In-Dash Flasher is perhaps the most widely used among pro anglers. The Lowrance In-Dash Flasher offers optimum performance in two depth ranges of 0 to 40 feet and 0 to 100 feet. It delivers superior high speed operation and glare-free readings in the harshest light conditions. Cost is around $250, including a transducer, along with a one year warranty.
