DIR compliant doubles manifold

[Tavi]

I like Thermos better than Halcyon (I own both). My Thermo has the barrel o-rings and came with rubber knobs.

The big difference is that the Thermo valves turn much easier than the Halcyon. In addition, the knobs are a bit bigger, which makes it a bit easier to grab them during a valve drill or flow check.

The Thermos turn easier than the Dive-Rite too. (I own both)

I use a thermo manifold with rubber handwheels, and the larger white nylon shims (less turns to close the valve).
