I assume that side navionics works great w my iPad 1 iPad 2 would only be better since I think it has a faster processor. The redraw is already faster than most chart plotters however don't expect the app to have all the functionality of a high end chart plotter I think they dumb it down on purpose or they would never sell their excellent cartography in a $5000 marine plotter

I found these are now available on Amazon for $97.25 with free shipping (Prime).

Here's the direct link on Amazon.

Craig - you mentioned you were a pilot. Commercial? I am a 777 driver and need a booster to get through the heating elements and ply of the glass on the flight deck. Have you any experience of this on similar machines? Cheers!

I've had one of these for about 7 months, and I wouldn't recommend it. It works OK on both my iPad and iPod touch, but I find it next to impossible to pick it up without it turning on, and sometimes it takes 20-30 attempts to turn it off. It's easier to just let it time out after 15 minutes or so without a Bluetooth connection. This power switch design would never have passed design qualification tests where I worked.
