Canister lights?

[matt t.]

I prefer a focusable light head, IMO you can't have to tight of a beam. A tight beam is best for signalling on a shallow dive or brighter days (lots of ambient light). If you get a deal on a fixed focus light I wouldn't necessarily turn it down though, depending on price and condition. I've never had a problem with the standard toggle switch. They're easy and cheap to replace if needed. My Sartek light had a screw cannister and it was o.k. Sometimes it would be a little harder to get apart than other times, but it was never a problem. The screw top does eliminate a flood from latch failure. My "H" light has the latches on the cannister and I've never had trouble with those either. My experience with dive gear (and most other stuff I do) that simpler (and plainer) is better in the long run.
