Simrad PI Depth Catch monitoring sensor
How deep can you go?
When the sonar and echo sounder
tell you how deep the school goes, it is good to know that you can
place your fishing gear at the same depth.
And even better,
you can monitor and hold the desired depth. The sensor design is rugged
and award-winning, and the Simrad PI Depth catch monitoring sensor
is available for three different depth ranges.
