Tec 3 for single tank?

[Johanan]

Hi!

I got an offer to buy a full set of regulators - two Tec3 1st stages (RH+LH), two XTX50, hoses etc. It seems to be a good bargain for the dollars. I don't dive doubles yet but maybe some day. Meanwhile I could use the both XTX50 as my primary and backup regs. How versatile the Tec3 is? I know that it can be used for a single tank, too. Yet, I wonder is it not an awkward solution? Any advise?

In my area DIN is the most common version, but it might be a problem in other places,right?

Thanks!

If helps I have same configuration :

new double valve and 1'st stages. - DIR Explorers

I wouldn't buy another Yoke reg. If your regs are DIN, and you are going to be using tanks with Yoke valves (rentals for example), you can always get a converter, and if you forget it, the dive ops/boats almost always have the converters laying around, too.

Thanks, Lucca! Did I get it right that you use both 1st stages on a single tank? I.e., you get a special double valve that you screw into your tank, then the both 1st stages in this valve and the hoses in both 1st stages? That is new for me. I was thinking of using one of the 1st stages for single tank diving and both of them for doubles. Can you tell me more about the advantages of your configuration?

Thanks, katepnatl! I was wondering about rentals. Good to know that there is a ready solution available also in the dive shops or boats.

We use that configuration for ''valve drill'' .

If you wear wet suit and dive single , you can use single TEC3 1 stage (it fails 1LP for wet suit ) because it have 3LP and 1 HP.
I have once in march that year opportunity to test separated stages becauce on primary reg fail o ring and tube start to free flow air. (On new reg ) So I cose primary vent and dive completly on secundar reg . Very positive !

Negative in my opinion is that is front with double 1stages and double ventils a little heavy and my trim go down on front.
But I have to sompensate with additional weight on back of tank.

Thanks, Lucca! Could you give me some good links where to buy H or Y valves? And which one to choose - H or Y? What brand? From what I was reading in other threads, Y valve vith dual dip tubes would give more redundancy...

for double vents like mine ( in that case you have to switch R/L but you can use tubes later for double tank ( longer tubes ) both SCUBATEC with rubber knobs (different price)

Scubatec Doppelventil / feststehend - TEC-DIVESYSTEME

Doppelventil für Monoflaschen


for TEC3 combination they use also that vent Scubatec Doppelventil

and it looks like on Halcyon mono wing (in that combination you'll use ORIGINAL APEKS DIR routing ... but you'll need shorter tubes )
