Just to clarify what I am looking for...I consider a side finder as a machine that shoots a beam from the boat to the shore. Basically a horizontal beam that would identify the slope of the land from the bank toward the boat and identify fish within the horizontal cone.
Some units have what sales guys refer to as "wide side scanning" which is basically a wide angle transducer and sometimes more that one transducer.
I'd like the first machine if I could determine if they will work well
Are there any experts out there that can advise
