I've got the Dedenbear Lightning 1. It's great as well. You can save two different times.
I have the wiring schematic if you need it. I've got mine wired with a plug in and it's mounted on a RAM mount so I can just put it in and take it out easily without having to actually install it in the boat. Nick Winski at Wintech did it - it's super trick. He did a great job.
