The progress capture device we see used the most is the Petzl Micro Traxion. It feeds incredibly smoothly, which is mostly why it is so loved. It features a cam lock-out function that turns it into a pulley. This can be dangerous if you forget to re-engage the cam before use. Always double check that your system will catch you on the ground before you start climbing and have redundancy with what grabs when you fall.

The Edelrid Spoc is another toothed pulley, just like the Micro Traxion. It also features a cam lockout function, but instead of a metal switch, it relies on a small piece of cord to hold the cam open. You can easily untie or cut this cord to disable the lockout function so you can't forget to shut it when you start. The cam on the Spoc sticks out from the housing during use, so be extra careful to cinch slack in between your devices rather than below both. This will keep your devices separate and functioning properly!

The Climbing Technology RollNLock relies on a ribbed cam rather than a toothed cam. Some people claim that ribbed devices will put less wear on your rope, which may or may not be true (we have not tested this). Either way, they will still de-sheath your rope at a similar force as a toothed device. Many ribbed devices require a lot more force to feed, but the RollNLock is by far the smoothest one. If teeth are not your jam, the RollNLock is the device for you.

Many homemade solutions have knots but these don't have any. They are easily adjustable whether you are climbing low angle or steep rock. These are extremely popular.

Grigri's are the iPhone of brake assisted devices. All around useful tool to have if you need to go hands free while on rappel to add your grabby devices back on or to hold you while you take off the grabby devices. Almost certainly you can use this gear anywhere else you can climb.

These are technically body positioning devices and not PPE personal lanyards because they are very static and if you allow any slack in them and fall, you could break something in the system. However, they are the easiest daisy to undo as you can literally be sitting on them, hold the tail and push the button. All other types require that you lift your body weight up.

These are the most common PAS out there and because of that they are out of stock all the time. The rope inside is dynamic and in theory, you could fall on it. It's never a good idea to fall on a PAS but this is safer than a purely static option. You have to lift your weight off it to pivot the head to extend it. Not a problem if you have something to stand up on. Difficult if you are freely hanging there.

Grivel's ascender is $20 cheaper than a Petzl one and it's handle can be used as a tubular rappel device or a spot to clip. It's got a giant thumb tab to open the teeth and works great. I've used it for years and think overall it is super good enough.
