I have an Ipad 3 (without built in GPS) has anyone any experience using either of the 2 GPS (Bad elf and GNS) in a Cessna 172 on a yoke mount?

I want to make sure the one I buy will work OK before ordering it. Thanks in advance

The internal GPS seems to work fine for most people. If it doesn't, you can always get an external one later.

My experience of using an iPad2 on its internal GPS has been very good in an aeroplane with a perspex bubble canopy - so no metal between the iPad and the sky. But in our Arrow mounted on a kneeboard, it consistently loses it's GPS signal - so much that I bought a GNS1000 external bluetooth GPS receiver. The GNS1000 is the replacement to the earlier one with the slidey-switch issue. Since the chipset is WAAS/EGNOS enabled I expect its accuracy and reliability to be better than the internal one.

Hi hope this helps plus its my first post!

I bought a Bad Elf Pro external bluetooth gps. Having tried the Skydemon software trial version I took the plunge and bought a subsciption inc. navigation. Clutching my shiny new Bad Elf dongle and Ipad I went for my first flight on Sunday down to Goodwood for lunch with a friend.

However no matter what I tried, the Skydemon software would not work in flight mode with the Bad Elf Pro. On the point of giving up, I shut down all the active apps apart from the ones you need for Skydemon to run and then restarted the Ipad. Skydemon then started working perfectly with the Bad Elf dongle!

Skydemon easily outperformed the built in gps in the plane with both the ease of flight planning and its navigation features.

Well done all at Skydemon HQ and Bad Elf for an excellent bluetooth adapter!
