PATCO lights dont look very appealing. Bulky, switch is on the light head which is something that I personally wouldnt want on a HID. To easy to accidently turn off. Most of their lights are only rated to 165ft. Think they sell an inferrior product compared to Halcyon, Stealth, or Sartek (which by the way also makes PVC canisters) or Dive Rite. Plus they have a non-DIR approved green cord on one of their lights. Would have to pass on PATCO!
