Computers offer additional features that vary among models. However, they help eliminate human error in calculating dive plans. Remember, no computer or dive planning table guarantees to prevent decompression sickness. Plan your dives conservatively and make minimum three minute, fifteen foot safety stops after each one. For more explanation on dive planning tools refer to Dive Computers, A Consumer's Guide to History, Theory, and Performance, Decompression Theory, Dive, Tables, and Dive Computers, and the PADI Encyclopedia of Recreational Diving.
Continuous breathing becomes ingrained with experienced scuba divers.
Just as the excitement of hunting can distract a diver from monitoring air, depth, and time, excitement can distract a diver from breathing continuously. Besides serving as a safe diving practice, deep, steady breathing also improves spearfishing effectiveness. Buck fever, as it relates to spearfishing, is the tendency for a diver to be unable to pull the trigger or to miss an easy shot due to over excitement. Continuous breathing is mandatory while scuba diving. Remind yourself before each dive to breath calmly and continuously.
