Mares MR12 Rebel Regulator

[do it easy]

Just to be clear, I believe it is set low (130-136) before the CWK is installed, then after the juice is sealed in place, the IP automagically returns to 142-148. I think the pressure on the environmental seal adds a few psi. Again, just my opinion.

I've never checked the IP once the CWD is in place, I'll have to do that some time.

I concur. Performance of the MR12 will not be sacrificed by putting a CWD kit on it. This is a great regulator at an awesome price. The MR12 has been in the line for a long time, it has proven itself to be a terrific regulator. The Rebel got very high marks by Scuba Lab last year for performance! It will be tough to find a better reg for the same value.

Little tech stuff.

For cold water it is always a good idea to have a lower IP to reduce possibility of freeflow. It will slightly impact performance but the reliability trade off is worth it.

The MR 12 uses a "wet" CWD which is "old school", it works well however. If the tech does not install it correctly (leaves air bubbles) it will have detrimental effects on the performance.

I can't see how the kit would cause a drop in performance. The tech might have to make a minor adjustment but it wouldn't be a problem.

If there are bubbles left in the kit they will compress rather than transmit the pressure unchanged to the diaphram, that connection should be via a non-compressible material.

how do you ensure that there are no bubbles in there at the time of assembly?
