Replace your mounting platform if it becomes lost, worn or for a personalized fit. You can choose a different size platform to personalize how it sets on your hand or mount:
FLAT- For mounting on flat surfaces such as altimeter pillows or mudflap mounts
STANDARD- Fits most hands comfortably for the best ergonomic fit and placement
HIGH- This mount is for small hands so that the Altitrack sits at the appropriate angle and position on the hand for better viewing.
