Hi All
Daryll from GB Falconry sent me and Adrian Halgarth (Scotland) a unit each, on first inspection I thought it a bit big so only really suitable for birds of around 2lb up, it fits on a track pack and lays neatly between the wings.
Switching on the unit, it goes into searching for sat etc, to cut a long story short, if your bird goes off you phone the unit up and it will ring twice then hang up on you, the unit on bird will then call you back with a text which when opened will bring up a map with its location to nearest postcode, and its altitude so you know how high off ground its s
