I've got a lake that has 200ft depths in it, and 80-100ft depths not a boat's length from shore ... but never have had to fish it deeper than 30ft. And most of the rest of the lakes I fish will have a thermocline develop @ the 15-20ft depth, in the heat of Summer. So I just keep the range set at 40ft & pay no attention to the bottom disappearing ... my baits are not going to be any deeper than ~20ft, anyway. I'm looking for the tops of cover sticking above the thermocline layer, or bait balls or schools of fish to come on screen .... regardless of bottom depth.

Even in 30ft of water ... the sonar beam is ~25ft wide on 800kHz .... and ~45ft wide on 455kHz

In the "more likely" category of the small lake "wackyman" is fishing, he'll probably be finding fish around the 15-20ft depth range. The sonar beam would be over 16ft wide at 800kHz & over 30ft wide at 455kHz ... in just 20ft depths. He shouldn't have any trouble getting images like this:

Hey CP, Wondering if you could do me a favor and take a snapshot of your settings sometime and post it or send it to me? Still trying to mine set to be able to see something like that pic on this post. I tried setting other fellers have posted and no luck.. I just wonder if there is something wrong my fish finder.. I see the fish I just don't get the structure like everyone else talks about .. Fishing in Truman there should be lots of structure, more trees in the water than out of the water ...Need someone close to be able to hook it up and try it to see what they get out of it.
