When using a choker hitch, no minimum is needed for which two measurements?

The correct answer highlights that when using a choker hitch, there are no minimum requirements for circumference and diameter measurements. This is pertinent because a choker hitch is designed to secure an object by wrapping the sling around it and passing the slack back through the loop. The effectiveness of this hitch is determined more by the type of load and how it is secured, rather than the precise size of the item being used.

With regards to circumference and diameter, their lack of minimum requirements means that a choker hitch can be employed effectively on a wide range of load sizes and shapes, allowing for flexibility in securing different types of objects without being restricted to specific dimensions. This versatility is a key advantage when using a choker hitch in various operational scenarios.

In contrast, the other measurements listed do have implications for the security and stability of the load when using slings and other rigging techniques, which is why they have more strict guidelines compared to circumference and diameter.
