End-of-Dive Letter Group
Table 1: End of Dive Letter Group
As you learned earlier, your body ingasses nitrogen as you dive. The amount of nitrogen you ingas depends on the depth and duration of your dive.
You need to factor the amount of residual nitrogen in your body when planning your next dive. So let's learn how to determine your letter group following a dive.
To determine your letter group, you first locate the correct row for the maximum depth you dove to. Next, follow the row until you locate your dive time. Remember, you round numbers up, so if your actual dive time is not listed in the row, round up to the next dive time.
When you locate the correct dive time, follow the column down to the letter at the bottom of that column, and that's your letter group.
