How long do dive computers last?
Many divers can use the same computer for years and years, but there may come a time when the unit can no longer be serviced by a qualified technician. Don’t continue to use a computer or any other piece of equipment that cannot be properly maintained. Most dive computers require annual or biannual service (refer to the manufacturer’s guidelines). In addition to replacing the dive computer battery (and transponder battery, if applicable) the O-rings must be checked, and the unit should be inspected for signs of salt buildup.Now that you know how often dive gear should be serviced, you may be wondering, “Can I do some of this myself? Yes and no (but mostly no). Some dive computers have user-replaceable batteries, and you can check for small leaks in your BCD or SMB by inflating them fully and submerging them in a bathtub full of water.
What to do if a dive computer stops working?
Remember, if your dive computer fails, stay calm. It’s not an emergency; it’s an inconvenience. Being proactive versus reactive will reduce the chances of this happening on future dives. For more information on dive computer considerations or secondary computer options, contact your local sdi dive center near you. Bottom line: if you don’t use a dive computer, you must calculate your dives the good old fashioned way[1] to avoid the danger of decompression sickness (dcs). Besides crunching numbers, dive computers offer many other benefits during and after a dive.
