which depth finder ?

[Eagle 1]

Since bream fishing has became a large part of what I do which side image unit would best serve finding beds ? I have used a helix-5 and may opt for a 7 inch . Any others that I should be looking at ?I typically crappie the same places (mainly brush piles) after the spawn so my elite 5 does OK for confirming locations . This unit will go on back to replace a lowrance elite 3 .
