Hey guys, I just recently bought a 2011 Lowe 1652 SC boat with a 50hp mercury off a guy at work. Great running boat with low hours on it, the guy I bought it off only used it a month or so each year to run trotlines to stock up on eaters for the year and stored it under cover the rest of the year. Anyways, the boat is in great shape but had no fish finder or trolling motor on it. I installed my old Garmin I had on my kayak and thought I'd be happy with it but as I get out into open water more I find myself wanting to invest in a nicer unit. I've been doing some reading online and talking to some bass guys from work and now I'd like to ask for some advice on here.
Since I mostly fish on Lavon and usually in shallow water I'm interested in a Side Scan GPS unit. That seems to be what would suit me best. I also want a 7 inch screen at least, preferably a 10 and my budget is around $800 give or take a bit. Really the only fish finder I've ever used is my Garmin and it doesn't do a whole lot more than just give me water temp. and depth. The models I've been looking at are the Humminbird Helix 7 SI, the Lowrance Elite 7, and the Garmin 7 striker.
What do you guys think would fit my boat / fishing habitat the best?
