an alternative is to buy a FF w/o gps, the $$ difference can be substantial, and then buy a $100 garmin gps unit. Some say their ff/gps combo units are not that accurate, have trouble getting on brush piles, etc., and revert back to a hand held gps (garmin) to get on the brush pile. I have a garmin 60cx HH, that I use to mark structure (I longline 99% of the time) and it will show me my tracks as well. Yes the screen is small but not a big issue for me now at 56. It really depends on how you fish, vertical, longline, spider, etc., as to what you "need" vs what you want.

I have a Lowrance Elite 5 pro dual beam on the front of my boat now, and with the garmin, I do ok, but I'm comfy with this set up, you may want a combo for the convenience. It has quite a few options in the settings once you figure them out, but alot of people on here like hb. It's a ford/chevy/blonde/redhead thing to some extent.
