  คำถาม: diver computer user error case study

  คำตอบ: A dive computer can also fail during a dive, due to malfunction or misuse. – Hardware failures. Mechanical and electrical failures: Leaks allowing ingress of water to the electronic components, may be caused by: Cracked faceplate…Seal failures can occur at joints, probably most often at the battery closure…Button failures are one of the more frequent problems, some models are particularly susceptible…Battery failure, such as running down unexpectedly, leaking, or failing to charge properly… There have been several instances where dive computers have been recalled due to significant safety issues in the software or factory calibration.

  คำถาม: scuba diving accident reports dive computer failure

  คำตอบ: Modern dive computers do it all…. While failure is relatively rare, when a dive computer goes “over the edge,” the diver can be left without this crucial information. Failure of a dive computer usually means you must immediately abort the dive… The best solution is to wear two computers…. Before a dive excursion, check the function and battery level to make sure everything is in working order. If the battery is low or shows any signs of physical damage, replace it immediately. Before closing the case, inspect the gasket or O-ring seal for any nicks or other damage; replace it as necessary…. Rinse your computer in clean freshwater at the end of the dive day, if not after every dive. This prevents salt, corrosion and silt from interfering with the pressure sensors, buttons or obscuring the screen.

  คำถาม: dangers of different dive computers on a buddy team

  คำตอบ: I wear two computers when tech and cave diving, but usually set one as a bottom timer. In more advanced diving, the computers can help to “check” a preexisting dive plan…. I have a backup mainly for when I go on trips where I’m doing 4-5 dives a day for 2-3 weeks. If a computer fails I can just use the backup and continue diving. Without a backup I’d need to wait ~24 hrs before using a different computer since it wouldn’t have my nitrogen loading…. If you do dive with two computer make sure running same algorithms as have seen over 15 mins difference on deco requirements between my and buddy computer after 30 metre dives…. If they are different algorithms and times are different, don’t we have to go with the most conservative anyways? We’re buddies, so it’s not like I can go without her…. As a rec diver, during 20 years of diving i had a single computer failure – as long as you dive in buddy pairs, stay within your limits and understand them, you have a redundancy and don’t really need a secondary backup.

  คำถาม: PADI dive computer policy and recommendations

  คำตอบ: You can track your dives using dive tables, a depth gauge and dive watch, but most scuba divers use a dive computer – it’s easier. A dive computer provides the real-time dive information you need to dive well…. A dive computer takes depth and time information and applies it to a decompression model to track the dissolved nitrogen in your body during a dive. Your computer continuously tells you how much dive time you safely have remaining. Your computer combines a depth gauge, timer and sometimes a submersible pressure gauge (SPG) into a single, useful instrument. The majority of divers have a computer because it makes sense.

  คำถาม: dive computer algorithm safety implications

  คำตอบ: All dive computer algorithms are intended to keep the risk of decompression sickness (DCS) to an acceptable level and work using theoretical models, based on research and data from actual dives…. Although the source data for most algorithms is the same, the resulting calculations often differ…. One of the primary reasons lies in differing methods of interpreting the data and adjusting large numbers of initial best estimates. Another obvious source of difference is in determining the maximum acceptable risk.

  คำถาม: DAN dive computer best practices

  คำตอบ: Dive computers are wonderful at carrying out programmed mathematical computations, but they are blind to the many insights you may have before, during and between your dives. For example, your dive computer knows nothing about your personal health status, your level of physical fitness or your individual susceptibility to decompression stress. It also knows nothing about your thermal stress or physical efforts during or between dives…. We do know that being warm (rather than cool or cold) during the compression and bottom phase of a dive promotes inert gas uptake (not optimal), and that being warm during the decompression phase promotes elimination (optimal)…. If you are diving with a group, do not forget that there can be considerable variability in the guidance provided by different computers or computers with different user selected settings…. if members of a group are using dive computers with substantially different models, and each diver wishes to follow his or her own device, it can lead to a breakdown in the buddy system.

  คำถาม: scuba diving accidents related to dive computer failure

  คำตอบ: Otherwise, the very short answer and the one that is taught in all agencies during open water certification is…if your dive computer fails on you during your dive, you immediately start a safe and slow ascent. There is no ifs, ands, or buts. The only but around is your butt getting to the surface slowly and safely.

  คำถาม: how can a dive computer be a risk for decompression sickness

  คำตอบ:…a dive computer can be a risk for decompression sickness (DCS) because it doesn’t take into account personal health factors…. It is important to remember that the mathematical algorithms a dive computer uses only provide guidance and must be evaluated by a conscientious diver…. Confirmation bias: The article states that confirmation bias promotes risky behavior, which means that getting away with a risky dive once or multiple times is still unsafe. Your susceptibility to DCS can change unexpectedly and suddenly.

  คำถาม: over-reliance on dive computers dive planning

  คำตอบ: A diver trained to rely solely on a computer may panic if their device fails mid-dive, unsure of their NDLs or next steps. Conversely, a diver who understands dive tables and rules can confidently manage the situation, follow a safe ascent plan, and avoid unnecessary risks…. One critical fact every diver must acknowledge is that decompression sickness (DCS) can still occur—even when following dive tables or computer recommendations and staying within limits…. Technology should enhance diver safety, not replace fundamental knowledge. While dive computers are an essential tool, they should never replace a diver’s understanding of dive planning, decompression theory, and personal limits.

  คำถาม: what are the reasons not to use a dive computer for a new diver

  คำตอบ: Computer users…are not forced to pre-plan in the same way, and some observers have noted that many divers using computers tend to “jump in the water, ride the computer,” and can be surprised when the computer indicates they have zero NDL left during a dive.

  คำถาม: GUE philosophy on dive computers and planning

  คำตอบ: DIR proponents believe that the most important piece of dive equipment is the diver, followed by the team, and the interactions between the team members…. The principle of buddy support and teamwork using basic, well practiced, familiar and standardised safety procedures is central to the philosophy. Use of simple, reliable, well matched and rugged equipment that is versatile in its application, and familiar to all team members is seen as the logical way to achieve the highest levels of teamwork and as a means of minimizing task loading on the divers by reducing drag, and allowing good trim and buoyancy control.
