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 many dives can I do a day?
For recreational divers, a typical limit is 4-5 dives per day as long as you follow dive tables or use a computer to track. For shallower depths, you will need to refer to dive tables to be able to determine how many dives you can safely do in a day and how long those dives can last.
What is the no decompression limit for 62 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 long can you dive at 30 feet?
Interesting question Spoon. Well strictly speaking they are time limits i.e (NDL limits) on dives to 12 meters (30 feet) however you’d need to be in the water for close to 4 hours on the first dive for this to be an issue.
What is no-stop time in diving?
The “no-decompression limit” (NDL) or “no-stop limit” , is the time interval that a diver may theoretically spend at a given depth without having to perform any decompression stops while surfacing.
Can you do 4 dives in a day?
The number of dives you can do per day depends on the depth and length of each dive. For recreational divers, a typical limit is 4-5 dives per day as long as you follow dive tables or use a computer to track.
How are the depths measured on the US Navy dive tables?
For the US Navy Dive Tables depths are measured in feet of salt water. Depths are listed down the far left side of the table. When planning a dive, always round to the next deepest depth.
How long can you dive for on a dive table?
Dive Table Rules. For example, if you do a dive to 18 meters (60 feet) for 22 minutes, the 22 minutes rounds to 25 minutes. However, if you become chilled during the dive, round the time again to 30 minutes. Avoid dives that take you right to the no-decompression limit for any given depth and time combination.
What are NAUI dive tables and why do you need them?
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. The letters range in sequence from A to L.
What type of dive planning information should I use?
If your dive buddy is using a different type, you should agree to use the most conservative dive planning information. The NAUI Dive Tables are composed of three tables: The NAUI Dive Tables are based on the US Navy Decompression Tables and have been designed specifically for recreational diving (figure 5-6).
