I'm looking for some opinions here for electronics for my Sportjon. As the title says, I'm debating whether to buy a fishfinder/gps combo or a less expensive fishfinder and upgrade my current gps that I use for hunting, hiking, etc. Obviously I can't carry my fishfinder around in the woods with me. 95% of my fishing will be done in rivers and lakes. I might make a trip to Valdez for silvers but I'm not going to be tackling any open ocean. Any recommendations on a unit would be welcome. There are so many to choose from it's hard to even begin to decide.
