Impulse QT-202 depth sonar

[duck-n-pond]

I have one of these depth finders, but no manual. Wondering what the pot adjustment on the rear is for??? Assumed buzzer volume as it was easily accessable, but since adjusting, I guess I was wrong (dooh!). Is it the depth tuning? Anyone have a manual or know where to download one? Thanks

On another post here, somebody mentioned a sensitivity adjustment. Could this be what it is???
