You need a cell phone
enabled iPad but you don't need an account or a sim card. It's just that the GPS chip is only found on the cell phone
enabled iPads. You don't even need a data plan. Just buy it and use it. Any mapping application will discover the GPS and locate you immediately. Get the latest one, much faster chipset.
In my case my iPad 3 is not GPS enabled but I tethered it to my iPhone and with iOS 8 it gets its location from the iPhone. The only glitch doing it this way is that the refresh rate is about 10 seconds late... Which, if you are sailing it doesn't really matter especially in my 16ft mini micro cruiser (I'll be buying
a grown up boat next August) It takes much longer to plot your position on a chart and if you are. Really in a hurry to find out where you are, just use your iPhone with Navionics or some other Charting apps.
iPad batteries will last a long time, in any case you just don't change the battery
, the unit is sealed... But iPad batteries are extremely durable and, if you take care of them they will last thousands of recharges, I have had mine for three years and I can still take notes at a meeting all day without having to recharge it, while it checks my email
Now, the GPS chip. When activated it takes a lot of juice and will cut the time to deplete the charge by half, this also depends on the app you are using, Navionics is not too bad, but others are constantly polling the chip... So just mount it on a special bracket and keep it plugged in while you are using it, all you need is a car charging
kit. Some people mount it on a swing arm in the companionway
so,it's visible from the steering
Memory... The wonderful resolution of the retina display comes at a price
... 32 Gb is ideal, 16 is on the poor side and may limit some of the things you wAnt to do.
Enjoy your iPad
