The Petzl Basic is the classic ascender from Petzl, used by cavers, mountaineers and access workers alike. It works by the toothed cam clamping the rope when downward pressure is applied. The large bottom hole will easily take two carabiners, lanyard and foot loop. The cam can be disengaged by hooking the trigger to the side.
The principal difference between the Basic and Croll ascenders is that on the Croll the top attachment is only on one side so that it can be worn with a chest harness to ensure that the device lies flat on the user's chest. This is primarily of use to cavers and other SRT users who are looking for the most comfortable way to ascend long pitches.

Customer Reviews of Petzl Basic
The newest, most compact design, this latest update to the many previous models of the Basic ascender sits comfortably in the adult hand without ever being too small or fiddly to work with. A single, half moon shaped lower hole provides ample room to fit multiple attachments, whether using maillons, karabiners, something else entirely or a combination of those. At less than half the weight of a handled jammer, the Basic offers a neat and significantly less bulky option for assuring onwards progress or gaining upwards travel on rope in an efficient manner. Having had a number of previous versions in my hands over the years, this one just feels good and is an indication of function-led development rather than change for the sake of it.
