It was a joke but it got me seriously thinking (which usually ends up with me spending lots of money). Anyways, the newer lowrance units including the HDS3 and carbon models have wireless connectivity built in. I found all kinds of vids of people hooking up tablets, both android and apple, to their units. They were able to actually control the units with the tablet touch screen, not just use them as a monitor. Large tablets are now available. Samsung has a 18.4 and 24 inch. There are also many others 12 inch and up. A couple of issues come to mind immediately tho. 1. Is viewing the screen outside in the sun going to be as good as the units? 3. Battery life 2. Rain is going to be a problem 4. It would be easy to drop in the lake with it on your lap. I suppose a fella could rig something up to hold it tho. The tablets I saw for sale were relatively cheap tho, from 200 to about 600. Here is a vid of someone hooking up his tablet. https://www.youtube.com/watch?v=6cQ3nR_LwW8
