The 2009 Petzl I’D S Descender is a self-braking control device and is equipped with an anti-panic function. A new multi-function handle has also been added.
The anti-panic feature is activated if the user inadvertently pushes the handle too hard. If this happens, the I’D S releases the pivoting cam thus automatically engaging the brakes to arrest the descent.
The handle has multiple functions. First, it allows a climber to manually control his descent by manipulating the braking side of the rope. This is done by unblocking the rope. Also, because of the button on the handle, movement in horizontal or low-angle surfaces is made easier. Finally, it allows a climber to position himself on the rope.
In the event that a climber incorrectly installs the I’D S Descender on the rope, an anti-error safety cam or catch reduces the risk of accidents. Taking up rope slack is made easier by a pivoting cam. The cam’s design improves rope glide when making an ascent. Thus, in conjunction with a foot loop and a handled rope clamp, you can use the ID’S for short ascents.
On the swinging side plate is a safety clip for quick rope installation. It reduces the possibility of dropping the descender. Passing intermediate anchors is also made easier.
The Petzl I’D S in designed to take 10 to 11.5 mm diameter ropes. It weighs about 530 grams, and comes in a variety of colors including gold, red, and black.
