Lightweight directional locker
The Positron is a great locker for directional loads, making it perfect for anchors, hauling, personal anchor systems, etc. Cross loading has never been an issue for me thanks to it's shape. It has a nice smooth action and the lock is never difficult to use, even with bulky gloves on. It's also virtually snag free, and pretty lightweight for a locking carabiner.
What makes is so great, it's size and tight D shape, also makes it a really bad belay locker, and it doesn't take hitches well... but for almost everything else, these are my go to lockers. I tend to carry more lockers than most, but these being so light and reliable, there's no reason not to carry a few.
