What is the name of the hitch that is tied using a carabiner and can be used to control descent during rescue operations?

The Munter hitch is specifically designed for controlled descent and is particularly effective when using a carabiner in rescue scenarios. This hitch allows the rope to run smoothly through the carabiner, providing friction that can be adjusted as needed to control the speed of descent. It is a popular choice among rescue technicians because it can quickly transition from a secure anchor to a descent mechanism without the need for additional equipment.

In contrast, the figure-eight hitch is primarily used for tying the end of a rope to create a secure loop and is not intended for descent control. The bowline hitch creates a fixed loop at the end of a rope, which is useful for leading a rope around an anchor point but lacks the necessary properties for safe descent control. The clove hitch is versatile for securing items but does not offer the controlled descent feature associated with the Munter hitch. This makes the Munter hitch the optimal choice for situations where controlled descent is essential during rescue operations.
