A popular canyoning descender, the Kong Hydrobot uses a magnetic central bar to secure the rope in place, rather than have it run around a carabiner. Not only does this remove the risk of accidentally dropping the descender when getting on and off rope, particularly while swimming, but it also reduces rope twist.
A horn on the top and cut-away section below the central bar provide additional friction settings which can be added while abseiling.
The magnetic central bar also allows the Hydrobot to be rigged in an auto-locking mode. This can be used when belaying someone, or in conjunction with a prusik knot to ascend ropes.
The device can be reconfigured for left handed users by simply unscrewing the central bar and reinstalling it in the alternate direction.
Note: While Kong says the device can be used with single or double ropes between 6 and 12mm in diameter, it is best suited for use with 9 to 11mm ropes.
Key advantages:
- inline design reduces rope twist
- no need to undo carabiner to get on and off rope
- magnet keeps central bar securely closed
- friction can be added while on rope
- auto-lock mode for belay or ascending
