I got a boat a few months ago I installed an ECHOMAP plus 93sv. I’ve been playing around a few lakes using my side imaging, I can see and pick out fallen trees, stumps and stick ups but can’t seem to see smaller brush piles. I have made passes by brush piles I fish and know are there but can’t pick them out. I have played with settings a little but have ran them mostly on default. Any tips on which way to adjust settings? Or is it just a matter of training my eyes to pick out the smaller stuff? Thank for any help
