[MEL-DC Diver]

Folks,
I am in the process of re-configuring my rig and am looking for some input on the SPG. I intend to have the SPG on a hose by itself and w/o a boot. The following are my requirements:

1) Be able to take your standard knocks and drops w/o an issue. Basically, a sturdy piece of equipment.
2) Display 100 psi increments
3) Ideally would have bar and PSI displayed, but will go with strict PSI if the 100 PSI increments are not available w/ the bar+psi config.

Based on what you are using and/or are aware of, what SPG do you know of that fits the above? OMS comes close, but doesn't make it on #3.

Regards,
MEL
