Sterling ATS Rappel Device
Sterling ATS Rappel Device
The Sterling ATS is a rappel device (released Jan 2011) that works a lot like a Pirana, with a few additional features. It provides about one level additional friction, so it works better for we canyoneers who weigh 170 lbs or more. Horns on both sides allow for more rope tricks. See the full review on CUSA Gear Guide.
(12-13-2020 My supplier is doing a poor job of keeping this in stock.)
The Critr has largely replaced the ATS, though the ATS is simpler, smaller and trimmer. Choice of rappel device is largely a matter of personal taste, and the ATS is definitely still in the hunt.

We no longer sell the ATC, as it is not a Canyoneering device, but I thought I would leave this here as a link to an interesting bit of history on the CUSA Tech Tip linked below.
And just so people know, if you show up to a canyon trip with an ATC, you shall be frowned upon, righteously. It is like showing up to a gun fight with a peanut butter sandwich. Although sometimes I bring one for belaying, or because it is a Grand Canyon trip and every ounce counts!
A truly stellar plate-style rappel device, the ATC-XP works especially well on small diameter ropes, and offers a variety of modes for different levels of friction. It is compact, and my device of choice when we are not doing very many rappels, but I like the Critr or Sqwurel better for more technical ropework.
