Factors to Consider when Selecting the Diving Technique When selecting the

technique to be used for a dive, the following factors must be considered:

■ Duration and depth of the dive Type of work to be performed Environmental conditions Time constraints

A dive of extended length, even in shallow water, may require an air supply exceeding that which could be provided by scuba. Specific depth limits have been established for each type of diving gear and shall not be exceeded without specific approval of the Chief of Naval Operations in accordance with the OPNAVINST 3150.27 series (see Figure 6-14).
