DESCRIPTION
Very similar to Mad Rock's Lifeguard, it has a very subtle but important difference. The Safegaurd (also referred to as the Lifegaurd Black Edition) has a springless design (everything is the same except the spring is removed). The springless design makes it more ideal for route setters, camera operators, arborists, riggers, rope access, and other specalty uses. It will not work well for lead climbing (the red Lifeguard is designed for that).
Normally, there is a spring that engages to keep the cam open (not shut on the rope), so it is easy to pay out slack to the lead climber. In this traditional sense, it is easy to move the rope in and out without resistance. Without this spring, the cam is always on, braking the rope. So any force from the climberes side of the rope, will keep the climber held at all times.
Lowering will be the same, you'll still use the handle and override the cam
