First post so hopefully this doesnt break any rules. I'm recently back into fishing since kids are older and work isnt as hectic. I only have a cheap aluminum boat. I would like to get a fish finder. As with all shopping I started looking for a really cheap model, then a slightly better one, now I'm thinking about a mega. I need side imaging as most of the lakes I fish are 2-4' deep with only a few 6-15' spots. How does the SI work in med to heavy weeds? I assume the thicker the vegetation the less you can see. Would spending extra for the MEGA be worth it versus a cheaper 5 or 7" model with CHIRP? I want to get the most out of the few hours of fishing a month I may get, but I dont want a $1800 finder in a $500 boat if I dont need it.
Also I like to fish different lakes to explore, I dont really have a main lake. I dont know if that would change opinions or not. Are there any options I need to have?
