When using the Recreational Dive Planner table or eRDPML I should ascend go up no faster than?
When using the Recreational Dive Planner (table or eRDPML), you should ascend (go up) no faster than… per minute or the maximum rate allowed by your computer, which is slower. … You want to do a repetitive dive to 12 meters / 38 feet for 32 minutes.
When using a dive computer I should ascend no 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 planning a dive with a computer I use the plan or no stop scroll mode to determine?
Before you dive with a computer, you need to read the manufacturer’s dive computer manual. … See Using Dive Computers and Tables I – Planning Dives with Your Computer. 42: When planning a dive with a computer, I use the “plan” or “no stop scroll” mode to determine. A the maximum depth of the previous dive.
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 fast should you ascend while diving?
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. Safety stops assist with reduction of excess nitrogen, which reduces the risk of DCI.
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.
How long can you dive 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).
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 do you need to decompress?
It can take up to 24 hours for the body to return to its normal atmospheric levels of inert gas saturation after a dive. When time is spent on the surface between dives this is known as the “surface interval” and is considered when calculating decompression requirements for the subsequent dive.
What should you do if you accidentally exceed the oxygen limits of your computer?
If you accidentally exceed the oxygen limit of you computer, ascend immediately but slowly, make a safety stop and end the dive.
