Does this include the bolt?
DAVID D Yes. All of them have the bolt. And to be honest I would not get the flashing one. It is annoying to other divers. I only got that one because the constant on type was not in stock. I'll replace it soon with that type.
WILLIAM G Yes, and 4 years later, if not more still works after about 32 dives.
DRAKE B Yes it does but you must choose the right diameter and thread size to match your regulator.
WILLIS R C When you say "bolt," you must mean the threaded metal section that screws into the yoke of your regulator first stage? If so, yes. When you buy this item, you need to specify which regulator brand you use, or the threaded section won't screw into your yoke; it must be the right size. For example, I own an Atomic Aquatics regulator, so I got one that fit that brand.
DANIEL M Yes the bolt is included, so during the order process you must make sure to specify the brand of Reg you have so it fits. I have ordered and used a few of these over the last 10 years they are great but you must be careful on dive boats, the deck hands are usually very "helpful" and will twist the red flashing part which turns it on or off. This results in one of two things the bulb gets drowned ruining the item or they turn it off then your dive buddy has to turn it back on.
JILL G Yes it does. This light has worked wonderfully
GREGORY J Yes, it is permanently attached to a bolt which replaces the one you tighten when you attach your regulator to the tank- so be sure to order the right diameter for your particular model of regulator. Having gone through several of these lights, I strongly recommend only putting it on when doing a night dive and making sure it is turned on before you get in the water.
JAMES A yes it includes the hole thing it will replace the one you have on your reg now. Make sure that you get the proper bolt size for your regular. Happy diving.
