@BubbleTrubble: After I looked into conversion kits for other companies, I'm a little surprised Hollis doesn't do it as well. The guy made it sound like there MIGHT have been a kit, but that it was either cost prohibitive or that it needed to be installed by a Hollis dealer (or both). I was hoping for better, but I'm not disappointed. One thing I AM disappointed by is that Hollis still hasn't shown up here. Oh, well...they responded to my phone call quickly. Anyone interested in calling them back and seeing what the answer they get is?
Hmmm. There's a
big difference between not offering a conversion kit...and offering one but recommending that installation be performed by a Hollis dealer.
I highly doubt that a DIN-to-yoke conversion kit would be cost-prohibitive. As I mentioned before, other manufacturers offer such a kit for $50-$70.
The Hollis dealer should have given a clear, unambiguous answer. It's not a difficult question at all.
Either Hollis sells the kit...or it doesn't.
Also, when I said "better" earlier...I meant that DIN on the reg and a DIN/Yoke converter is better than Yoke on the reg and Yoke/Din converter. Reason being that when diving Yoke, it's all the safety of Yoke. When diving DIN it's all the safety of DIN. Yoke on the reg means that when diving DIN, I still have an external Yoke connection so it's no better than diving yoke in the first place. That's all I meant.
If your reg is yoke-configured, you must use it with a yoke tank valve -- there is no manufacturer-approved yoke-to-DIN adapter.
In order to make a yoke-configured reg work with a DIN tank valve, you need to convert the reg to DIN.
As I mentioned previously, most manufacturers have conversion kits to convert the a yoke reg to DIN and vice versa. You'll need the kit, appropriate tools, and torque specs to do the conversion properly.
If your reg is DIN-configured, with the aid of a DIN-to-yoke spin-on adapter, you can still use it with a yoke tank valve. No tools are required. The adapter just spins onto the DIN threads, and you use the adapter to make the yoke connection on the tank. The only disadvantage of this kind of connection is that it can make the reg jut out a little more. Depending on how the tank is mounted on the BC, some people complain that such a connection bumps into the back of their head.
