Spyros, As an owner of one of the cave megs from the movie, I can tell you this: If you can find one of the covers and someone is willing to sell it to you, you still don't want it. Believe it or not, it increased drag on the unit if I recall what Jill told me when I bought my unit from Joel through her. The cover was a 'Hollywood' spice it up thing to make the Meg look futuristic. It had no 'practical' purpose. Eric Thanks guys, anyone has a link to the cave cover? this way everything should be well protected right? personally i like my set up like this. Cheers Cedric. that is the article i used as my guide when decided to invert mine!!! ![]() Spyros

I have also de-inverted my tanks – and I am quite happy with the setup George,I think cedric’s article mentioned above summarizes pretty well the advantages As for the Solenoid stuck open scenario, the way I practice it is un plug the QC4 quick connection and run the unit via the manual O2 addition inflator leaving the O2 tank open. To unplug the QC4 can be really a pain as it is in a bad position – but you only need to do it once ever thought of having a shut off valve on the solenoid hose? i keep thinking about this one all the time. haven't decided yet. like to hear other opinions about this as well. i mostly dive manually so only use the solenoid once or twice for short periods of time mainly for keeping it in good condition. i thought that there would have been many responses to this, but it seems that not many share the same opinion to us... i guess time will tell.

Spyros, wow, thanks for that Eric.As an owner of one of the cave megs from the movie, I can tell you this: If you can find one of the covers and someone is willing to sell it to you, you still don't want it. Believe it or not, it increased drag on the unit if I recall what Jill told me when I bought my unit from Joel through her. The cover was a 'Hollywood' spice it up thing to make the Meg look futuristic. It had no 'practical' purpose. Eric i nearly made myself get one... Spyros

Spyros As long as the QC can be reached I think that the shut of valve is not a good thing as it brings added complexity with out actually adding something important [FONT='Calibri','sans-serif']At least that’s my thinking (so far....)[/font] |

Much cheaper option and apparently longer scrubber times.i mostly dive manually so only use the solenoid once or twice for short periods of time mainly for keeping it in good condition.

| Jonny The Hatch ![]() Current Rebreather/s: | Re: De-Inverted Tanks on Meg. Who has done it? So out of curiosity and in the (unlikely Megs don't fail) event your solenoid did fail open have you guys tried to do an accent from a serious depth while maintaining a constant PO2, opening and closing the tank valve in the so called de-inverted position? Or are you just bailing out to OC? It seems to me that if you wanted to stay on the loop you would be in for some serious hard work during the trip home ? Cheers Chriso Hey Chriso, Well what i would do in case of a solenoid would fail open during a dive is to unplug the solenoid an continue to dive the unit manually. Oh yeah, i dive my meg with valves up. /Jonny

![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() | Re: De-Inverted Tanks on Meg. Who has done it? My avatar says it all. Pros: Better trim without adding weights, shorter hoses, standard SPG hose perfect length Cons: Valves more exposed to overhead So out of curiosity and in the (unlikely Megs don't fail) event your solenoid did fail open have you guys tried to do an accent from a serious depth while maintaining a constant PO2, opening and closing the tank valve in the so called de-inverted position? Or are you just bailing out to OC? I don't see how/why it is any more work than having the valves down. The valves are about 6 inches behind each of my ears and are very easy to reach. Unsure how it'll all work out with a soon to be acquired drysuit though.It seems to me that if you wanted to stay on the loop you would be in for some serious hard work during the trip home ? Cheers Chriso |
