Backup to ipad/skydemon
I have an ipad which and I'm going to subscribe to skydemon
I have an iPhone and a garmin 495. I tempted to sell the 495 as it's too big and wit the ipad I'd never use it's bells and whistles. However what would everyone recommend as a backup to skydemon? Preferably something that has European charts too. Happy to use something on the iPhone but if so what? Or should I buy a cheapo GPS unit, or just stick with the 495?
