## What is repetitive dive?

Repetitive Dive. This is any dive that you make before you have completely offgassed from any previous dive or dives. Residual Nitrogen Time (RNT) This is the amount of time you must consider as already having been spent at a given depth for a planned repetitive dive.

## How many dives can I do in a day?

PADI standards limit students to 3 training dives per day. However mixing training and non-training dives is a bit of a grey area. A student could do 3 training dives and then a fun dive and that doesn’t violate any PADI standard.

## At what depth do you need to decompress?

The need to do decompression stops increases with depth. A diver at 6 metres (20 ft) may be able to dive for many hours without needing to do decompression stops. At depths greater than 40 metres (130 ft), a diver may have only a few minutes at the deepest part of the dive before decompression stops are needed.

## How long can a scuba diver stay at 100 feet?

Nitrogen is absorbed more readily at deeper depths, making how long can you SCUBA dive dependent on how deep you are. For instance, the time you can spend SCUBA diving at 100 feet is 20 minutes whereas if you limit your dive depth to 35 feet, you could stay for 205 minutes (if you had enough air).

## What is the no decompression limit for 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.

## How long can you dive at 60 feet?

A not uncommon 2 tank dive trip might be the first dive at a max of 90 feet with a max time underwater of 35 minutes while the second dive might have a profile of max depth of 60 feet with a max time underwater of 50 minutes.

## How long do you have to wait to dive after flying?

How long of a wait is really required? DiveCompare author Mike, notes that, “…the recommendation set out by PADI [the Professional Association of Diving Instructors] is: For single dives, a minimum preflight surface interval of at least 12 hours is recommended.

## What is no stop time diving?

A “no-decompression”, or “no-stop” dive is a dive that needs no decompression stops during the ascent according to the chosen algorithm or tables, and relies on a controlled ascent rate for the elimination of excess inert gases. In effect, the diver is doing continuous decompression during the ascent.

## What is bottom time in diving?

bottom time. Time used in calculating decompression obligation from decompression tables. For most tables this is defined as the elapsed time from starting the descent to starting the final ascent to the surface, excluding ascent and decompression time.

## How do you decompress when diving?

Decompression diving involves on-gassing more nitrogen, which means a diver must make a series of stops during his ascent. Each stop allows time for gas to move out of the tissues and back to the lungs. The diver then continues to move closer to the surface between each decompression stop.
