What does a "hot drop" refer to in deep diving?

A "hot drop" refers to the practice of dropping directly onto a pre-assessed dive site from a boat. This technique allows divers to quickly reach their designated dive location, often in situations where currents or other factors might make traditional entry methods less practical. For example, a hot drop is commonly used when diving on reefs or specific underwater features that may be difficult to access from shore or when the surface conditions are not ideal. This method emphasizes efficiency and is often used by experienced divers who have carefully planned their dive sites ahead of time, ensuring safety and proper navigation upon entry.

The other options do not encapsulate the specific meaning of a "hot drop" in deep diving, focusing instead on unrelated aspects like water temperature and group sizes.
