Lotta peeps using an ipad for navigation and I can see why...I put a navionics app on my new iphone and it's fookin' GREAT!!...has all the detail and MORE of the chart functions that my chart plotter has in the boat...arrow follows the course over water, displays speed over ground and the contrast, picture quality is world class...and when not in boat, can be used for laptop computer...so it's a two-fer that's hard to beat...comes in black or marine white and there is a boat mount you can get for it...fo shizzle!!...
