Take a look at the Elite-5:

I recently decided on this unit and it is great. Doesn't have the HD screen but the standard screen is better than most anyway. $250 bucks less and has most if not all of the features of the HD that you would use on a yak. One-handed head removal is great for quick storing during surf launch/landing. West Marine has them online or you can have your local store order one in for pick up.
