I think it's a pretty cool deal. My big question is battery life. I can also see where there is a possibility of some "lag" between what is going on below you and what you see on the screen. Maybe not, but it's an Android tablet and unless they got a priprietory hardware platform, there might be that possibility. Time will tell, and it won't take long.
$1700 for a Marcum flasher with GPS seems way too much for me. I have their LX6 and use my Humminbird 597 w/ Lakemaster chip out of the boat (powered on the ATV). If the ice is too thin for the ATV, I have an older Lawrence H2O with a Lakemaster chipEven if I had to start out with new stuff now, I could have the same functionality at less than $1700 Am I missing something?
Hurry up and buy one. Marcum needs beta testers so they can start working on the dozen future software updates to try and fix the issues.
