Thank you and God Bless

I have the Mark 5 pro (dual beam) and like it except for one thing. If you use the fish symbol option on this model, the fish symbol is very small, and I haven't found a way to "enlarge" 'em yet. If you're gonna mount it close to eye level or at the console, its a good FF. Has lots of features, like you can scroll back to see what you might have missed while doing something else, has a flasher option, split screen, 2x screen, easy to operate as well. I had two on my tracker, then upgraded the one on the front, then upgraded the one on the console, so I put one on my yak, and have now upgraded the one on the yak to gps/ff to reduce the clutter (eliminated the HH gps). I have two of 'em not being used, so if you decide on the Mark 5 pro, let me know, can make you a good deal on 'em. have everything needed to install, all brackets and mounts, pwr cords, TD, etc.

I have a 581 I & it's never gave me any problems whatsoever & colors never been a problem for me anyway. With the Navionics card it's a pretty good outfit. I run it in console & a 798 ci si on the trolling motor & both have been flawless.
