Hi Everyone,

I've been crappie fishing for a long time with a cheap eagle unit. I can go and catch some fish just knowing water depth and temp, but it's time for us to start catching some numbers. So I want to be able to side scan for brush piles, etc. at the back, (tiller steer) and then move up to the front and use DI to pinpoint the fish. I want to mount the unit at the bow and be able to watch the SI on my Ipad at the back of the boat. I think I've narrowed my search down to a Lowrance HDS or a Garmin EchoMAP.

What's the best/cheapest unit that will fit my "wants" with a minimum 7" screen? Preloaded with a map would be a plus but I can add it too. Thanks!!
