Search the internet for the topic, “How to Fine Tune Sonar,” and you will find lots of results, many offering in-depth tutorials on tweaking advanced features for today’s down-looking fishfinders.
Yet my long-time fishing buddy Mark Wisch, owner of Pacific Edge Bait Tanks in Huntington Beach, California, one time showed me the simplest ways to dial in your sonar to see bottom structure and fish.
Go State-of-the-Art
Before we go there, however, I will say this: Buying a state-of-the-art fishfinder and matching transducer is the first step. You can opt for a multi-frequency chirp system (which I highly recommend).
Yet some conventional sonar that pings on a single frequency work nearly as well as a chirp system. Furuno’s RezBoost system for the NavNet TZtouch and TZtouch2 multifunction displays is a great example of how conventional sonar can be engineered to rival the fishfinding capability of a chirp fishfinder.
Secondly, the auto modes on fishfinders better than ever, again thanks…
