Dropped $180 on a depth sounder upgrade for the dredge last week
Old one kept giving false readings in murky water. New one has a wider beam angle. Has anyone else had trouble with bottom detection in heavy silt?

Wider beam angle is usually the fix for silty bottoms since it gives you a bigger footprint to work with. The narrower beams just punch through the muck and miss the real bottom completely. A lot of guys swap to a 20 degree or wider transducer and it solves the false reading problem right away.

Oh, I hate to nitpick but a wider beam actually gives you a smaller footprint in deeper water since it spreads out more. The narrower beam is what punches through silt and gives you a cleaner reading on the hard bottom below. You might want to try a 10 or 12 degree element instead of going wider.
