What is the difference, practically between sealed, and not sealed. Don't any advantages of being sealed disappear after it is opened up for it's first servicing?
Thanks for you answer
If you dive primarily in cold waters, you need to make sure that the regulator you???re getting at least meets the European Standard for cold water regulators (as defined by EN250), which means that the regulator has been certified for use in water as cold as 2 to 4 degrees Celsius (35.6 ??? 39.2 degrees Fahrenheit). If the manufacturer???s documentation indicates that it meets US Navy Standards, that???s even better. Those standards indicate that the regulator has been certified in waters as cold as 28 ??? 30 degrees Fahrenheit (-2.2 to -1.1 degrees Celsius). Design methods for achieving cold water certification vary, but in general it involves sealing the first stage and using a heat sink on the second stage to recapture some of the heat in the diver???s exhaled breath.
If you???ll be diving in waters that are silty, sandy, or high in dissolved solids, you???ll want to get a regulator with environmental sealing as a feature.
Your regulator will be resealed after being serviced.
The 1st stage is sealed not the reg. Prevents water from entering when switching out tanks.
As far as I know, it has to be resealed again. The sealed reg is for diving in cold weather and helps prevent the reg from freezing. At one point I was diving in a quarry with temps running about 46F which is pretty freakin cold. I don't do it regularly but thought why not be prepared if I do it again. Hope that helps.
No, when the first stage is serviced (and thoroughly cleaned) it is resealed and reassembled.
When they say sealed all they mean is that the first stage has a filter inside when your remove the dust cap no small debris can get in. My Oceanic FDX is a sealed reg, for the little extra money I think its worth it and it also depends with how well you taker care of your reg. I am very meticulous with all my regs , its your lifeline , even when I do live aboards or charter boat dives I always politely ask the crew if I can attach my reg to their tanks.
Ask fa as Atomics , BUY It !!!! That's how great their regs are, I went with the B2 and was gonna buy the T3, until I found out that the T3 still has brass internals and the only Titanium was the exterior of the reg, titanium internals is not Nitrox compatible and that's why the T3 is basically the same as the B2 . Hope this helps, and by all means if you have the money buy the T3 sealed its their top of the line unit !!!! Safe diving my friend - Maverick Hawaii Diver
Thanks. But aren't all the regs nitrox compatible up to 40%.? Just not a higher %.
