    This discussion has been split off from Two new studies



    Yes looking forward to hearing more about the study, I have found the rEvo RMS very effective, though hardware has had it's problems but seem to be resolved now.

    My rEvo had old temp probes and boards in it when I bought it used. rMS was working. On my second day of training, the rMS died. Since then, I replaced one temp probe and the solenoid board. It all worked for a few dives, then the other temp probe died and I replaced that one. I don't have all that many hours on the new parts, but they are still working.

    I did note that the new temp probes look slightly different than the old ones I replaced. I'm just hoping the new look represents a newer design that is more reliable.

    I’m living with RMS for 6 years. The RMS components definitely have improved in reliability, so my view would be that the components don’t fail as frequently. Now that I have built up confidence in my ability to dive the unit safely, my plan is to remove the RMS completely as it is widely proven to not be reliable and for deco dives I use a new scrubber each dive. It’s a great system and it’s a shame they can’t get it to be reliable.

    Why remove it?

    Whenever mine has failed, it just stops reading one of the temp probes, so it stops giving me any rMS data. It doesn't affect anything else. It doesn't give me false readings. Just no reading. And, mine has never crapped out DURING a dive. It just seems to somehow die between dives, so it gives me no reading during my pre-jump and I know my situation before I get in the water.

    I cannot say whether I would spend the money to fix it again. I guess it depends on how long all my new parts last before the next thing breaks. But, as long as it keeps working, I'm going to use it. I did 2 days of diving in NC a few weeks ago and the rMS gave me plenty of confidence to use the same sorb for both days - no re-packing a scrubber at the end of the first day. It was only a total of just under 4 hours, both days combined, so it was within specs, regardless. But, without the rMS, I would have still re-packed one basket at the end of the first day.

    Because the failure mode for every RMS component is the same, they remain in the switched on state and drain the ext battery and when that is dead it then defaults to draining the internal battery. My record is having new internal and external batteries drained within 48 hours.

    What do you call a device that automatically connects to any open hotspot? Oh, right, that's called a prime target for hackers. I'd guess that many divers put contact info into their computer -- in case of loss or emergency. For example, my computer displays my email address & DAN membership number. That info is personal enough, particularly combined with geolocation data, that I'd never want it promiscuously sent out via random hotspots.

    I do strongly agree with you about the benefit to standardizing data formats, but differ in that I think uploads should only occur voluntarily, knowingly, and after an affirmative action, certainly not automatically and defaulting to "opt-in".

    The new probes I have had in my unit have worked as they should for the last 18 months, as Stuart V mentioned above they have been redesigned. The first three years I had my rEvo I went through 9 RMS probes all replaced under warranty. I replaced one set out of warranty at my cost these failed, they were replaced under warranty and are the probes I currently have.

    I experienced this issue, though probably not quite to your extreme, the board was replaced under warranty no problems since.

    My first failure ended up being one probe and the solenoid board. The solenoid continued to work. Only the rMS part of the board no longer worked.

    I dived something like 4 more days in a row after that, with no battery issues.

    I also dived numerous other weekends with those bad components still in there. I never noticed any premature battery drain issues.

    Delighted to hear you've had no problems with the new components. Best of luck with them for the future.
