I bought the Pro+ model when it first came out last year. It allows up to five devices to connect, so my idea was to use it with Navionics on my LTE iPad but also use it with other devices that don't have built in GPS. It didn't work out well. There were huge problems with the device crashing. On several instances it was completely unresponsive and wouldn't reboot until the internal battery
died. Bad Elf eventually fixed that issue with firmware upgrades, but another problem persists. The bluetooth connection with iOS devices is unstable. The connection drops out several times a day. The only way to re-establish a dropped Bluetooth connection is to reboot both the Bad Elf and the iPad (or iPhone
, ITouch). This is a major PITA and not something you want to deal with on a device you're using for navigation
. Bad Elf technical staff made a heroic effort to find a fix for the problem, but ultimately said they couldn't do anything about it (it's an Apple problem) and offered me a refund.
If the Bad Elf actually worked reliably, there would be another important benefit to using it with an LTE iPad. When you sail out of LTE signal range, the iPad wastes a lot of battery
power searching for a signal. There's also significant power spent on GPS reception
. By using an external GPS, all radios except Bluetooth can be turned off on the iPad. This should greatly improve the iPad's battery life.
