ATLAS is more than just your regular altimeter. ATLAS is an all in one device that can act as your altimeter and audible (even when on your wrist) and whilst it's doing this, it's also acting as your log book and canopy piloting altimeter - clever!
As if all that functionality isn't enough, it's made from hard wearing aluminium, so is much more resistant than plastic altimeters to cracking! Plus, it's waterproof up to 6ft for an hour, handy should you ever intend on doing pond swooping or beach landings
ATLAS can be updated by the user themselves for FREE using the USB interface. So every time the manufacturers design another new feature - you get to play with it for free too!
