Dive Computers: Picking The Right Algorithm

An algorithm is the mathematical formula a dive computer uses that factors in real-time measurements of depth, gas mix, time at depth—and, depending on the algorithm, potentially lots of other data—to calculate how long you can stay under water with a reasonable degree of assurance that you won’t get hit with decompression sickness (DCS).

There are currently about a half-dozen different algorithms being used in dive computers, each using its own proprietary computations, and each with its own “liberal” or “conservative” leanings. Computers that use more conservative algorithms lessen the risk or likelihood of DCS by limiting dive time. Computers that use more liberal algorithms provide the opportunity for longer dive times, but, of course, more time spent at depth also increases the risk of DCS.

So which is best? It really comes down to the individual diver’s comfort level. However, divers who have preconditions that might make DCS more likely (age, poor circulation, poor physical conditioning) should always go the conservative route. Most new computers offer methods for programming personal safety adjustments that let you increase the conservatism of virtually any DC.

5 Easy Steps for Maintaining Your Reg

A modern regulator is an extremely reliable mechanism. So reliable, in fact, that some divers will take their regs on countless dives and never so much as rinse them off. Yet they keep on delivering air year after year.
While this is indeed the modus operandi for the maintenance-challenged individuals among us, the truth is, a regulator is a pretty hefty investment, and when you spend that much on something it kinda makes you want to take care of it. We’re not talking a major commitment here; we’re talking a few minutes after each day of diving following some simple steps to help extend the life and performance of what is really the most important component of your life support system.

This is all it takes:

1. After a day’s diving, making sure the dust cover is in place, give the reg a quick rinse with a low-pressure hose to knock off any big chunks of dirt, sand or salt.

2. Drop the reg in a bucket of fresh water or the bathroom sink and let it soak for 10 minutes or so.

3. During the soak, swish the second stage around in the water (without depressing the purge button) to get water flowing through the mouthpiece and exhaust tee.

4. Pull the reg out of the water and give it another gentle rinse, making sure you hit all swivels and hose connections. This will require pulling back the hose protectors—if your reg has them—so you can get at the connections to the first stage.

5. Give the first stage and second stage a gentle shake to clear any excess water from the yoke and the exhaust tee. Then lay it loosely coiled out of direct sunlight to dry.

Balanced vs Unbalanced Regs: Does It Make a Difference?

One of the features mentioned in ScubaLab’s regulator tests is whether the first and/or second stages are “balanced.” In recent years, the terms “overbalanced” and “hyperbalanced” have popped up as well, adding to the sometimes confusing mix of features to evaluate before choosing a regulator. We won’t get into detailed technical aspects, and this explanation doesn’t cover every reg in the market, but here’s a simplified explanation.

balanced-regs
Balanced First Stage
It’s all about the springs when discussing the difference between balanced and unbalanced first stages. With both piston and diaphragm regs, there’s a high-pressure valve and seat assembly and a spring. An unbalanced reg basically has a different pressure on each end of this valve-spring assembly that causes varying effort to overcome the force of the spring as conditions change — such as change in depth or tank pressure. This translates as variations in the medium pressure traveling through the hose to the second stage, resulting in harder breathing effort at depth or low tank pressure. A balanced first stage routes medium pressure air to both sides of the valve-spring assembly, so that the effort to move the spring is consistent and unaffected by variations in external conditions, giving the diver unvarying pressure to the second stage and consistent breathing effort.

Over-Balanced First Stage
This is a bit of technical wizardry performed by some manufacturers allowing a first stage to slowly increase its medium pressure output as ambient pressure increases (you’re going deeper) instead of keeping it constant. The advantage is that the relative volume of air supplied to the second stage is greater as you go deeper, theoretically making breathing easier. A nice bonus on those deep wreck dives.

Balanced Second Stage
In oversimplified terms, a typical second stage has at its heart a valve and a spring, much like the first stage. When a diver inhales on a regulator, the inhalation effort opens a valve that is closed by the tension of a spring. Balancing a second stage is accomplished by routing medium pressure air to the backside of the valve to help counteract the force of the spring. This allows the valve to open with less effort, making the reg breathe easier under heavier demand, such as the higher pressures at depth.

The Bottom Line
If balancing makes things so much easier for the diver, why isn’t every regulator manufactured that way? One reason is cost. If you open a reg and look inside, the parts are tiny and precision made. Balancing adds a layer of complexity to the manufacturing process that translates into higher cost. Another reason is that not everyone needs a balanced regulator. As our tests prove, an unbalanced system can perform very well in entry-level diving scenarios. Purchasing a balanced first stage paired with an unbalanced second stage can often provide a good balance of performance at a reduced cost to the budget-conscious diver.
