What type of fishing? deep or shallow water. If you are bass or walleye fishing its mostly shallow water ( less then 50 ft) If you are trout land locked salmon or stripers then its deeper lakes , at least out west. I ask because as much as I like the side scan and other live scan features their use for trout and salmon, even in fresh water , is limited and you can save money with a good down scan only set up. If you do not need radar or auto pilot you can save even more with a good stand a lone unit. As if you are looking for a screen out back just for fishing you might not want to two new units, one for in side and one for out, but one wifi unit and a pad of your choice. You can mirror one to the other and not buy two units. Lots to think about. So what is your real use and what is your budget. Then shop with in those two needs. There really are no bad units anymore just what set of features are useful to you. Do get a unit with at least mapping built in or on chip. I would love to go back and fish a bunch of lakes that I fished 20 years ago before good FFers and mapping.
