Maximum Dive Time
Table 1: End of Dive Letter Group
Before you begin a dive, it's important to determine how long you can safely remain at your planned depth without being required to perform a decompression stop before surfacing.
Maximum dive times are indicated by a red number enclosed in a circle. To determine the maximum dive time for a planned depth, you first locate the correct row for the depth, then follow the row to the right until you find the circled time.
For example, if a dive team is preparing to dive to 83 feet, the first step is to locate the correct row. Remember, if the exact depth is not included in the table, you round up to the next greater depth in the table. So for an 83-foot dive, the 90-foot row is used.
