Optima vs Tempstick

Did you notice that majority of the responders above who don't like Temp-Stick have never used it ?

I have used it

Q: Do you let the temp stick determine when you change the scrubber or the time on the scrubber?

Q: If your breathing rate went up a fair bit and the temp stick said everything was OK (This happened by the way) would you stay on loop or come off it. (He decided it was OK coz the temp stick was OK then proceeded to develop the situation into a big hit)

I dive in the UK and i tend to do one big dive and thats that change the scrubber. 45 @ 60m 2 1/2 hours job done. Or i do a fun dive with my friends 90mins on a 35m dive then a hour on a drift maybe second dive job done change the scrubber.

I very very rarely get past the three hours on a scrubber. EXCEPT when i travel abroad say on a red sea livaboard. THEN I would use the scrubber monitor to rip the piss out of the fill over four or five dives. As it is i generally monitor my 02 usage against the scrubber size and do maybe 5hours then bin it.

SO despite my reputation for buying every electrical gizmo out there I feel absolutely zero desire to have a temp stick. If it came free with the unit id have it if I had to pay extra for it I wouldn't bother. Its a gimmick and a potentially dangerous one its right up there with air integrated computers on my "don't need it its just more to go wrong" list.

If there was an option of a C02 monitor id pay happily for that.

I don't own or dive an Rebreather yet but here's my view from a newbies perpective.
The tempstick is a magnificent feature of the vision electronics and i cant see why anyone wouldnt want to have it anyway. Its just something to add to your safety-just have one and dont use it maybe one day it will get you out of trouble.

Of course a direct method of measuring CO2 in loop -RELIABLY- would be far more useful but if i'm not mistaken no such system is operational yet.

I'd really like to see what the next step of Rebreather design will be, cartridge scrubbers, co2 monitoring and an onboard computer with PSP capabilities to help time on deco pass by???

Because...

By your own admission you see it as a safety feature? Why?

The safety feature is surely changing your scrubber within the manufacturers recommended limits. The decision to bail off loop should be based totally on the fact you don't feel right. You should not be encouraged to stay on the loop by information on screen which may not be relevant to your given situation.

A properly packed scrubber will not fail within the guidelines of run times laid down by AP so is the temp stick relevant?

A temp stick will not reliably detect a scrubber failure so is it any use for this if it cant be relied on? It measures reaction temperature in the stack, not C02

Q: what exactly will you be using the temp stick for?

As i repeatedly say if its on there fine, but I wouldn't pay for it.

Are you saving your money for the 4th HH set ?

Hang on, shouldn't i have just used the bowling ball clause

Come on put up some form of logical defense of this expensive gimmick. I have put forward my case where is yours?

Your point is valid. I said a co2 monitor would be better if it was reliable. I wouldn't pay for it either,it provides inadequate information but if it was standard item i wouldn't mind.

I like the temp stick.
I take it for what it is. A bunch of thermometers up the center of the scrubber. I think that is useful information. If it looks wrong I'll probably call it a day early. So I'm a coward. Heros die young.

It's like a dive computer. It does the maths for some deco algorithm and tells me what that would advise. What I do with this information is my call. If you surrender you brain into obeying one computer or one table you will, in the end, get a bad steer and it will be your fault. Take all the inputs you can get and make your own plan.
