My budget is around $1,000 but I would prefer less than that, what unit do you suggest for side imaging.My practice has been to troll the bank and hit up fallen trees, but I am thinking a side imaging unit will let me see structures and venture into new areas. I have been reading how people like the older generation of Humminbird side imaging units more than the new ones that just came out, any thoughts? Lowrance Vs. Humminbird?
