“At plus 5” is the TTS if remaining at the current depth for 5 more minutes. This can be used as a measure of how fast you are ongassing or off-gassing. “At plus 5” is the TTS if remaining at the current depth for 5 more minutes. This can be used as a measure of how fast you are ongassing or off-gassing. The predicted change in TTS if you were to stay at the current depth for 5 more minutes. A positive “Delta plus 5” indicates that you are ongassing the leading tissue while a negative number indicates that you are off-gassing the leading tissue.” So, what exactly is "Delta plus 5 and At Plus 5" on your Shearwater computer? These are simple indicators that you can use to identify what would happen to your time to surface if you stay at your current depth for an additional 5 minutes. In essence, it's a handy measure of how fast your body is either absorbing or off-gassing nitrogen. It's like a little diving crystal ball, giving you insights into your dive's future. Now, here's where it gets interesting. If your current depth is shallower than your average depth, you're essentially off-gassing. Staying at this depth can result in a lower Total Time to Surface (TTS) at the end of your dive if you remain there for a period of time. Think of it as off-gassing at a less than ideal depth. But how much are you off-gassing? That's where Delta Plus 5 or @ Plus 5 comes into play. Let's break it down with an example. You were at a depth of 40 meters but You're now at a depth of 25 meters, and your current TTS is 15 minutes if you ascend right now. However, you still want to explore for an extra 5 minutes. What happens to your TTS? Delta Plus 5 tells you that after those 5 extra minutes at your current depth, your TTS will be three minutes less than it is right now. In other words, you're off-gassing at this depth, and due to the current depth being shallower than your average depth you would now have a delta of -3, thus reducing your TTS by 3 minutes and allowing you 5 extra minutes at the new depth. So, it's a trade-off: two extra minutes of off-gassing for five more minutes of underwater fun. Worth it, right? To put this more simply… TTS or Total time to the surface is your time to the surface right now…Delta plus 5 gives you an indication of how long it will take you to ascend to the surface if you remain at your current depth for 5 more minutes. With this information, and through the indicator of being either plus or minus, you can determine the efficiency of your on or off gassing. Now, the only difference between Delta Plus 5 and @ Plus 5 is how the numbers are presented to the diver. Delta Plus 5 focuses solely on the change in TTS, while @ Plus 5 predicts what your TTS will be five minutes from now if you don't change depth. Same numbers, just a different way to look at it. But even if you find these calculations a bit mind-boggling, they're still incredibly useful. Knowing what those extra 5 minutes at your current depth will cost you in TTS can be a game-changer, especially when you spot something exciting towards the end of your dive. Now, remember, the average depth I mentioned is just a rough approximation. Shearwater's computers use a complex algorithm that considers various tissue compartments with different parameters, like m-values, tissue speeds, and gradient factors. It's all about giving you a general concept of your off-gassing dynamics. Another way to monitor your current gradient factor on nitrogen loading is with the GF 99 and Surf Gradient Factor. GF99, which stands for Gradient Factor 99, keeps a close eye on your gas absorption and the leading tissue compartment. It shows you the current percentage of gas load against the M-value, helping you understand when you're on-gassing or approaching super-saturation. During a dive, this monitor will show the diver when they are on-gassing and when the lead tissue compartment is beginning to increase in saturation toward the M-Value or supersaturation in the percentage gradient. 0% means the leading tissue super-saturation is equal to ambient pressure and Displays “On Gas” when tissue tension is less than the breathered inert gas pressure. 100% means the leading tissue super-saturation is equal to the original M-Value limit in the Bühlmann ZHL-16C model. GF99 is displayed in Yellow when the current gradient factor modified M-Value (GF High) is exceeded. GF99 is displayed in Red when 100% (un-modified M-Value) is exceeded. And then there's SURGF, the Surface Gradient Factor monitor. This provides a predictive analysis of your total percentage of M-value or gradient if you decide to surface at that moment. It's like having a safety net, allowing you to stay informed about your dive's safety margin.

While teaching a class, I had a few students ask about the density in gas difference and calculating that difference in relationship to sac rate calculation. While we briefly touched on a question that was quite fair, I may have glossed over it a little too quickly with a response that was more of a statement that the difference between gasses and capacities in a cylinder was negligible at best. The longer answer to this question is to take into account the "Z Factor" when calculating the gas capacity of a cylinder. But, before we touch on what the Z Factor is, it is important to consider the ACTUAL capacity of the tank. IE many tanks hold as much as 10% LESS air than the size commonly used to describe them and up to 20% LESS for gasses other than air… IE Catalina S80 Aluminum is listed as 80 cubic feet, when in fact it is 77.4. This is one of the nice things with many modern, HP Steel tanks. These tanks tend to be more accurate in describing the actual capacity. IE Faber HP 100 is actually 100 cuft. But, the issue becomes the sheer variety of tanks available for diving. Using the manufacturer-listed Liter Volume creates a much more concise and accurate standard of measurement that divers can more easily rely on. Once we are able to fully appreciate the accuracy of using the published Liter size of a particular tank, we can begin to take into consideration the Z Factor for the gas that we plan to dive. The Z Factor is used to determine how the gas will compress in a cylinder and is used to calculate its Compressibility Factor (Z). This factor has differing values based on Gas Temperature Total Pressure So, for example, The Z factor for air (dry) @70F - 2015 PSI = .9984 ---- IE 80 cuft alum true capacity 80.1282 air (dry) @70F - 3000 PSI = 1.0320 ---- IE 80 cuft alum true capacity 77.5193 air (dry) @70F - 3600 PSI = 1.0615 ---- IE 80 cuft alum true capacity 75.3650 Nitrox 32 @70F - 2015 PSI = .9912 ---- IE 80 cuft alum true capacity 80.7102 Nitrox 32 @70F - 3000 PSI = 1.0214 ---- IE 80 cuft alum true capacity 783238 Nitrox 32 @70F - 3600 PSI = 1.0491 ---- IE 80 cuft alum true capacity 76.2558 Trimix 10/70 @70F - 2015 PSI = 1.0833 ---- IE 80 cuft alum true capacity 73.8484 Trimix 10/70 @70F - 3000 PSI = 1.1262 ---- IE 80 cuft alum true capacity 69.1921 Trimix 10/70 @70F - 3600 PSI = 1.1529 ---- IE 80 cuft alum true capacity 69.3902 To calculate the true cylinder capacity of a gas, divide the ideal capacity by the Z Factor. Now, with this, it is worth noting that this is not a straight line, but rather a curve and has a variance that is dependent on the amount of pressure. In the end, there is a general average that can be counted on. It is also worth noting, that different gasses create different SAC rates for multiple reasons, and it is to your advantage to make sure that you are tracking your SAC throughout a history of diving and dividing all dives into categories... IE EAN dives (and again divided by the different levels of EAN), Air dives, Cold Water, Warm Water, Sea Level, Etc. Also, keep in mind that factors like travel and hydration, as well of course as diving effort should be noted to be able to help determine an accurate dive SAC rate profile. While many new divers refer to their computers and simply look at the PSI per minute SAC rate, this is far from being anything that can be considered very accurate or very useful for more complex dive planning. This is one of the reasons it is so important to ensure that you are using the manufacturer-listed Liter capacity instead of the described cylinder size or relying on a PSI per minute based on a formula that is missing most of the important data needed. By using the metric liter size of a tank and multiplying this by the BAR pressure, you are able to determine a more accurate picture of the actual amount of usable gas within instead of guessing based on a potentially inaccurate classification number in cubic feet. To increase the accuracy of this raw data, adding the Z Factor calculation will give the diver a more accurate picture of the amount of gas available and prepare them to be able to plan their dives accordingly. Being able to remove as many variables from the gas calculations helps ensure a much higher potential for success and preparation for potential emergencies that may arise. Capacity calculations also ignore the fact that it is difficult for a diver to breathe the residual gas in a tank below about 150 psi or 10 bar due to regulator flow restrictions and the fact that pressure gauges can be significantly inaccurate, especially when it comes to lower levels of gas. With this, it becomes even more important to always plan your dives with a generous amount of reserve gas. Adopting a policy of diving the rule of thirds helps ensure that the diver is not only more prepared for an emergency that they might have but also for one that their buddy may experience as well.

The biggest secrets and challenges to working with skills is twin sets The diver never learned correct functions in simpler setups. What I mean by this is that advanced setups like twins magnify issues, not create them. When you really understand the setup of a single tank and are able to accomplish technical skills to demonstration quality, then you are ready to move to twins. Using the same skills in twins becomes much easier. When doing any skill... SLOW DOWN. This means everything. If you think you are going slow, slow down even more. The more you focus on each PART of the task as an individual skill, the better it will be and more fluid. If you don't have time to do it right the first time etc. SLOW DOWN. RELAX in position and practice the simple hover. If you can't relax and hover, you aren't ready for skills. The relaxed hover is one of the most critical skills you can become proficient at. Check your balance. If you can't put your knees and ankles together, close your eyes, and breathe for 30 seconds without falling in any direction, you are out of balance and need to find a center balance. Sometimes it is just a matter of shifting gear around, but sometimes a little trim weight helps too. Start with moving gear around. I have found that I needed to add a spool to my left pocket to balance myself from left to right. Valve drills. Extend your arm all the way out to the right (or left if you use your left arm) then take it over your back. It will prevent the tendons from bunching up and allow you to reach farther back and probably allow you to reach your valves and isolator. These are just a few tips that we teach in Fundies. Which brings me to the most important. BEFORE YOU GO INTO OW with ANY Setup like this, dial it in while in the POOL FIRST. You should be able to do these skills in a pool comfortably first and ANY OW should only be an evaluation and review of their quality. Diving an unfamiliar or new setup in OW is asking for issues. Just my suggestions as a Tech instructor for Sidemount and TwinSets.
