When using the Recreational Dive Planner table or eRDPML I should ascend go up no faster than?

When using a dive computer I should ascend go up at a rate not faster than *?

A diver should ascend most slowly from his safety stop to the surface, even more slowly than 30 feet per a minute. Nitrogen in a diver’s body will expand most quickly during the final ascent, and allowing his body additional time to eliminate this nitrogen will further reduce the diver’s risk of decompression sickness.

When using dive tables divers must ascend no faster than a rate of foot per minute?

Similar rules will apply to any new set of dive tables or dive computer that you might use to calculate your dive times. Ascend no faster than 9 meters (30 feet) per minute. This is 0.3 meters (1 foot) every two seconds. You need a timing device and a depth gauge (or a dive computer) to measure your rate of ascent.

When using the RDP How should you plan a dive that will be under cold and strenuous conditions?

When planning a dive in cold water or under conditions that might be strenuous, plan the dive assuming the depth is 4 meters/10 feet deeper than actual. The eRDPML allows divers to calculate single, repetitive and multilevel dives using either metric or imperial units.

How fast should a diver ascend?

You should never exceed an ascent rate of 10m/minute when diving shallower than about 30m. . An ascent rate of 5-6 metres per minute is recommended in the last 10m of ascent. Complete safety stops on all dives that exceed 10m depth.

What is the most efficient breathing pattern for scuba diving?

The most efficient breathing pattern for scuba diving is: A deep balanced inhalation followed by a long balance exhalation without any pauses between inhalation and exhalation.

How long can I 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 long can you dive at 50 feet?

BSAC and PADI no-stop dive times:

15 metres (50 feet) dive depth: BSAC no decompression time limit of 74 minutes (PADI Tables 80 minutes).

How deep can you dive without decompression?

There’s a bit of physics and physiology involved in a full explanation, but the short answer is: 40 metres/130 feet is the deepest you can dive without having to perform decompression stops on your way back to the surface.

What happens if there is no display on your dive computer when checking your equipment before a dive?

Dive computers are rapidly becoming an integral part of recreational Scuba diving equipment, and most divers will seldom dive without one. … If the computer malfunctions, and you are only diving an NDL (No Decompression Limit) profile, and you know that you are well within your NDL, simply abort the dive.

What is the no decompression limit or NDL?

The no decompression limit (NDL) is the maximum allowable dive time that you can remain at a specific depth and ascend directly to the surface without requiring staged decompression stops on the way up. Remember the higher the partial pressure of nitrogen (ppN2), the shorter the dive time (NDL).

How are bends treated?

The bends are treated in a hyperbaric recompression chamber.
