The Alti-mount is a great solution for chest mounting a visual altimeter. The Alti-mount is a carbon fiber 'L' bracket that slip into the ring covers or mudflaps on the front of your skydiving harness and with 2 simple Velcro straps locks it in place so your altimeter is in the same place every time regardless of body position.Most importantly, the Alti-mount is designed not to interfere with the operation of the 3-ring release system or cutaway handles.
