Is this a good product to use to attach to yourself so others will recognize you in a night dive?
Yes. This is a good product to use in a night dive. It makes very easy to indentify divers at night and permits a much more relaxed night diving. You can just concentrate in observing the sea life without any worries, as the green light will allow you to know immediatly where the rest of the divers are. It is very easy to attach to the tank and does not interfere with your dive at all. The light lasts for about 45 minutes to an hour - enough for the entire dive. I would use it again in a night dive.
