Craigo, good brushpiles take more than one tree. And it depends on how deep it is as well as to how big it looks on the graph. A lone tree set in 35 feet of water is hard to find because it is rather small in area and therefore is hard to find. Also if you will tie a gallon milk jug in the top of the tree it will stand the tree up and since air is 1000 times less dense than water it makes a good reflector for sound waves, hince it will show up well on the graph. BTW what you see as fish on the graph is really a reflection off the air bladder in the fish for the same reason. The fish itself is actually a very poor reflector.

That's me. Nearly always catch a few, hardly ever catch a ton. I am working on this. One thing that is a big deal for a lot of novice anglers such as myself is our inability to understand our electronics. Right now, I'm sinking brush piles and looking at them from many different angles so I know what different sizes and types of brush piles look like when I come across them, whether they are mine or not. Last year I put out my first piles. Out of the first 3, I never have found 2 of them, and I have them marked with GPS! Talk about frustrating. Hopefully this year will be better as I spend more time on the water with my nose in the graph more and more.

I have been fishing for Crappie alot lately and sometimes I just don't understand them. I went to Lavon Friday morning and found only single fish on each tree. No matter how well I fished the timber I would only pull one fish off of it. The funny thing is each fish was 2 lbs or more. The largest per fish average I have every experienced.
