Downscan-is that side scan? Or 360 degree "scanning sonar"?

I am totally new at this. I bought the Lowrance Mark 4 last week. Cabella's had a nice clearance sale - $219 instread of 299. I want it for locating ledgy areas in my lake at home. I am getting into searching for lost fishing gear and the rocky areas are where you find the fish and lost gear.
Downscan is DSI technology. Part of the varied sonar technology package that Lowrance, and I think Hummingbird[sp?], are currently using for underwater structure identification. I am not familiar enough with it to teach
YOU about it. It looks down directly under the boat and gives you a cross sectional graph that is almost a photo-like view of the water column and terrain you are passing over.
I am presently learning how to use it. Haven't got to the "posting images"
stage in my knowledge yet.
If anyone is really interested, Google "dsi sonar". There are several YouToob presentations that talk about it a little.
