MAX 150 - descender

The MAX Descender is the most versatile constant rate descender on the market today and is packed full of innovative features. Models are available for both automatic hands free operation and multiple descent models with advanced rescue functionality, as well as power assisted option (separate Checkmate approved drill required).

MAX-150 models are single user devices, with a maximum all up user weight of 330lbs(150kg). The device is designed to be used attached to the anchor point in regular mode of operation, or in an inverted mode, attached to the user and/or casualty. The device is completely symmetrical, allowing full use of all functions regardless of the direction the MAX is running. This also gives full functionality for each multiple descent or rescue.
