How do you do NAUI dive tables?
Dive Table Rules
- Ascend no faster than 9 meters (30 feet) per minute.
- Use the exact or the next greater number listed in the table for your depth.
- Use the exact or the next greater number listed in the table for your time.
- Use the deepest depth you reached during your dive to determine the dive schedule for your dive.
How is adjusted maximum dive time calculated?
To find your adjusted maximum dive time, begin by locating your current letter group on the right side of the table. Then follow that row to the left until you reach the column for your planned depth. The number in red is your adjusted maximum dive time. If this number is absent, a dive to that depth is not possible.
How do you calculate decompression stops?
Usually newer dive computers incorporate Deep Stops into their algorithms, and alerts divers when to take a Deep stop. However for those recreational divers wanting to manually calculate when to take one, simply divide your max depth by two and do a 30 second to a minute stop there.
What is RNT on a dive table?
Residual Nitrogen Time (RNT) — Represents, for repetitive dive planning puroses, the amount of nitrogen remaining in your body from a dive, ro dives, ade within the prior 24 hours. Adjusted Maximum Dive Time (AMDT) — That is how long you can stay at a certain depth in a repetitive dive.
What is a good sac rate for diving?
What Is A Good SAC Rate? There is no such thing as a good or bad SAC rate as this will differ between diver to diver. On average a new diver may equate a 25 or 27 litres per minute but a relaxed and experienced diver may equate 15 to 18 litres per minute.
Can you get the bends at 60 feet?
You shouldn’t ever come up faster than 30 ft/ min. unless it is an absolute emergency of life or death. Even at relatively shallow depths, when breathing compressed gases underwater, there is still a risk of decompression sickness.
How long can you scuba dive at 60 feet?
What is the No Decompression Limit for 60 feet? The NDL or No-Stop time for 60 feet / 18 meters is 56 minutes according to the Recreational Dive Planner table. On a Suunto dive computer using their algorithm, the NDL is 51 minutes for your first dive.
How does the NAUI dive time calculator work?
The NAUI dive time calculator is based on the NAUI dive tables, but it eliminates the calculations required to determine Letter Groups when you make more than one dive. The dive time calculator also reduces the errors that are often made when reading dive tables.
Do I need a copy of the NAUI dive tables?
Please note that due to differing screen resolutions and color depths, not everyone will see the data equally clearly. NAUI naturally recommends that each diver own a personal copy of the tables. The NAUI Dive Tables use a Letter Group designation to express the amount of residual nitrogen in your body.
