Скачать или смотреть HK Mini OSD Mk3 - test

Straight out of the box - thrown on to a Quad and then took it for a spin around the common.
The GPS actually works on this version (the previous versions had 1HZ GPS that were practically useless).

You have to push a button to save the home position. On the plus side they claim that you can push the button after finding three or more sattellites!
It has a good clear display with everything you need. Not very customiseable but the accuracy seems to be there and the home direction indication works!!
I'm not sure why they chose the letter B to as the icon for home ('B for Base' may be) but It works so who cares.

Overall, for less than $40 - It's a big thumbs up from me
