I have both, the turn lock gets bumped easily and the electronic lock of the newer one works well but you have to remember how to use it but most of the time I have a cheap ebay light clipped off that I find more useful, these are very short have a slide switch that hits a few different brightness settings and can be bought for a bit over $20 with a 26650 battery. Not as bright as the x-tar but for me as bright as I usually need, in lower viz like Monterey brighter often is worse the not.
Link?
I love my Dive Rite CX1. Was about to buy another one and just realized its discontinued now. Sad, its an amazing light just was a bit pricey at $159
That's too expensive (for me) for a handheld dive light. When it gets lost (for me) the tears would be a little bigger than if it was a $50 light. A lost $50 hasn't killed my dive....I think a lost $159 would!
