I have been away for a while due to medical issues but I'm back. I bought a new Tracker and I'm trying to find an old post that explains how to adjust sensitivity on any sonar unit. One of the test were to move a jig up and down under the transducer and you coul see it on the screen. I can't find it. Please help.

I do not know the specific post you mention (others may) ...
The most important aspect of seeing the jig on the screen is keeping the jig within the reach of the Sonar cone ...
Most units today operate 2d at 83kHz and/or 200kHz with Sonar cones similar to the diagram below ...
Then increase Sensitivity (Contrast in Lowrance)(Gain in Garmin) until the jig shows on the screen ...
