Well I've been looking into finally taking the dive and getting a fishfinder. This will be my first unit ever. None of my friends have one either. I mainly do alot of Lure Bass Fishing, so i cover alot of water in ponds and small lakes. I'm speculating that its not going to be too hard to learn though. I'm pretty good with electronics. Anyway, I'm looking for the the best portable FF that i can get under $200,preferably under $150, but will spend the extra $50 if worth it. This is the boat I'm putting it on http://www.pedalboat.com/oz/4/com/fish/sp8/sportsman.html and thats pretty much why I want a portable Unit. portablehttp://store.humminbird.com/ccombo-ccomboBuddy.html And if i go fishing with a buddy I can have a depth finder in his boat. I usually only fish ponds or small lakes. I dont have a trailor, I left the boat in and out of truck. I've been looking at getting the Humminbird 120 or 130 portable. The RF15 kinda looks cool but for some reason I wouldnt fill comfortable with that wireless transducer http://store.humminbird.com/ccombo-ccomboSmartCast.html. Both type units have really good reviews. Does anyone here use one?
