Garmin Striker 7?

Has anybody ever used the Garmin Striker 7? I'm looking for a FF for my backup kayak, and was originally planning to spend $200 or less. So I was considering the Lowrance Elite 4 @ $150 or Hook 4 @ $200.
But, then I saw this thing on sale and thought hmmm, I never had a 7 inch screen before haha!

I have it. Its a great fishfinder but the gps sucks because it wont accept a map so all you can do is mark waypoints.
