Hi Matthias, you can see in Custom Functions Description Manual this: "CF16: Estimated distance to decompression stop This value sets the estimated distance to the current decompression in meters. Usually, the stop is done below the shown value. This value increases the forecast of the total decompression time. Example: CF16=0.5m - The decompression stops are made 0.5m below the

Thanks Matthias, we will check that there is no penalty via simulation. Anyway, could you tell me how how CF16 value increases the forecast of the total decompression time? BR

I will try to explain the subject a little better. For example. She has to make a 3' deco stop at 9 m. If she stays fixed at 9 m and the 3 minutes go on, then the computer will show the next stop of X minutes at 6 m. But if she stays fixed at 8.9 m then the numbers on the screen turn red and, even if she is longer than 1 minute at 8.9 m., deco time does not goes down. Only if she re

Hi, My dive partner has an OSTC 2C. She says that when It marks a deco stop she has to be right at that depth. Otherwise, it penalizes by increasing the total deco time. For example, if she must stop at 6m and up to 5.9m, the computer gives her an alarm signal and increases deco time. I do not understand nor do I think this computer behavior is logical. My OSTC plus does not show any ala

Hi Ralph, thanks for the explanations and for the attempt to bring some reasoning based on deco theory into the discussion.I think it's being very instructive and it makes sense. Imagine a square dive with its maximums established: max. depth, max. bottom time and turn press. This is the pre-dive plan A. Additionally, you carry a contingency plan B,usually +3' bottom time and +

Hi Ralph, I think I understood what you wrote, although I do not see the direct relation that it has with the subject beginning of the topic "gas change suggestion".I think everything you've written previously is compatible with the previous function "gas change suggestion". I totally agree, the dive is pre-planned and you should dive that plan. We have all learne

Hi Arno, I know it. That's the theory and that's the way it should be. But Helium is not always available. Here we say: "Air to inflate bicycle wheels" ;-) It is clear that we can make the gas change through the menu. It's just seems faster with the gas switch suggestion, especially since you have to press the buttons a few times. And of course, No one should b

Hi Ralph, the link that quotes (this one, in English) was started by me. You told me that topic had already been raised a few days ago in this one. So I will continue writing in this that I think has more information. you said ascending to the first stop has been given priority over switching gas. It is more or less established among technical divers than in dives, with air as botton

Hi, Today I've made a dive and on the ascent, when I get close to the configured change depth of the gas,my OSTC did not suggests me the appropriate gas. It's strange because it has always worked, but not this time. I have changed by entering the menu. What can be caused this? I do not remember making any changes to the OSTC set up. My Gas Set up was: Gas1: *Air (White

Hi Matthias, respect to subsurface, I have been unpairing and repairing a few times.

Hello, I have updated to v3.01 and I have noticed a new set can be chosen. On settings/display settings/more/2nd depth I can choose between max. depth or average. I suppose it refers to what the display in dive mode informs, right next to the current depth. However, the average depth can be shown in the middle of the display through the right button.So, I do not find very useful to

Hi Ralph, yes, Steve Burton says that since the solubility of N2 is 4.5 times more soluble tan He, N2 percentage should never increase more tan 1/5 the reduction of the He percentage to keep the aiming point for the disolved gases the same. This is a simple rule whe can take in count whe we plan our deco gases. Anyway, I was wondering what we should do if during a dive we see the IBCD wa

Hi, as we can read in howOStech, page 35, an isobaric counter diffusion occurs when the N2 content in a tissue increase while the He content decrease. I was wondering until what % increase of N2, with respect to % decrease in He, considers the howOStech to be acceptable and from which the IBCD warning appears on the display. BR

Hi, just arrived from a dive and really worried. The facts have been the following: I have started the dive normally. the OSTC works correctly. At 26' we go up to the surface. OSTC keeps on working. 12' later we descend again. when we go start the return I look at the OSTC to see the compass and I find the black screen. The OSTC has stopped working.I try to opérate pr

Hi, taking into account that the OSTC Planner differs in the calculations made by the OSTC plus and the internal decoplanner from my OSTC plus it's not to planning tool since the operation with only two buttons is very limited, I would like to ask a question.

Hi, I have tried to do a decoplan with the OSTC planner and subsurface. In both cases I found that the calculated deco is different from that calculated in the OSTC plus itself. I want to make a decoplan for a dive with the following data: Botton depth: 43 m. Botton time: 30' SD: 100/100 GF: 30/85 Bottom gas: Air Deco gas: NX50 The problem I find is that depth and time incre

Hi Ralph, I have just done the same simulatorwith OSTC plus. Current surface preasure 954 mbar. Surprisingly, the dive plan is different even with the one previously done with this same computer. Just 1' with mine and 4' with yours. On single gas air, GF30/85, 30 m for 29 mins it says: 15 m 1 min 12 m 1 min 9 m 3 min 6 m 5 min 3 m 13 min TTS 29 min, CNS

Hi Ralph, - I am using the deco calculator from the simulator menú in both computers. - Yes, single gas, air. Just to make a simple test. I understand the few differences in the ascent and the increase of the gas need prediction. I have also notice that the rate of ascent in the OSTC2C is a constant value for all depths. But these differences are supposed to increase the TTS and t

Hi Ralf, On the plus I am using hwOS Tech v2.97 On the OSTC2C v2.80 is the current versión. Both of them set to Bülhmann 16 with GF factors. OSTC2C set by default saturation factor to 110% and desaturation to 90%. I suppose with ZH-L16+GF decotype saturation factors are not taken into account. OSTC plus set saturation factors to 100% for both. BR
