DMM Sentinel Screwlock HMS Carabiner

The Sentinel is one of the lightest mini HMS locking carabiners on the market, but more than that it is a really good multi-functional locking carabiner that works really well as a both as a small HMS and also, because of it's slightly offset shape, works as a great rigging/multi-purpose screwgate.This is because DMM have used a slightly offset design that increases strength and directs heavy loads into the spine, but uses gently curved top bar with a generous rope radius that allows it to work well with both single and double rope conrollers.
