So a 5 sec interval is standard. It is not a random interval.
This ^^So the fun part in that case is that three grey transmitters turned on at proper intervals have in fact less chance of collision than green, gray, and yellow.
But with mixed transmitters if you get a collision of signals, you get one. 5 seconds (or so) later they clear. With matched transmitters if you get a collision of signals they will keep colliding until one of the clocks drifts off enough.
Going through my checklist doesn't includes adding a timer to turning the first valve on and timing the second to be far enough off. I would be the one who opened the second valve at 15 seconds delay instead of 12½ seconds.
I just finished a TDI AN+DP+sidemount course, and in the process, I learned (among other things) that my Aeris Elite T3 is completely inadequate for tech diving, even in gauge mode. The primary issue is that it shows elapsed dive time in hour:minute format only, and when the instructor had me running the deco schedule, I needed to see seconds in order to know when to give the appropriate signals (the rental Suunto Zoop was fine for that). It should still be okay as a backup depth/timing device, and I need a redundant computer anyway, so I'm considering options now.
My criteria are:
I looked at Oceanic VTX and OCi; both are available for ~$500 with transmitter, but both appear to have the same problem of showing dive runtime in minutes rather than minutes:seconds. Looking at the user manual for Aqualung i750TC, I also see only minutes. Are there any other options, or should I just bite the bullet and get a used Perdix AI, then run it as a backup when I dive CCR?
- Air integration with 2+ MH8A transmitters. I want to be able to dive sidemount and see my remaining pressure on both wrists.
- Hour:Minute:Second time display.
- Integrated compass would be a plus.
- Reasonable cost. I'm planning to crossover into CCR next year, and when I do, I'm pretty sure I will want a NERD 2 with it. It's kind of hard to justify the cost a Perdix AI and a NERD. If there was a way to run a NERD with OC sidemount, I'd just get one and be done with it, but seeing as how its OC mount is to a regulator hose, that won't work for me.
You may want to contact Shearwater and their latest version is V72. I know when I am diving on OC Tec mode deco clear shows minutes and seconds. I do not know if this works on closed circuit.
But with mixed transmitters you're guaranteed to get collisions.
Not if you don't turn them on on the same 0.20 or 0.25 second interval.
If you turn on your grey one, and then turn on your green one at 4.90 seconds, they will never collide
