How long does the laser actually stay on? One review says 14 secs. another says 2-3 minutes.

14 secs is about right, but, it turns off 14 secs after the last motion it detected. Therefore, as long as there is something (like a car or person) moving, it won't turn off.

I haven't gotten that far along, but I'm estimating at least six months. The light only stays on about 15 seconds so it can go longer. I used alkaline batteries.

OK, I'm confused. Does it stay on as long as it keeps detecting motion, or does it turn off after 10 minutes or so regardless if you are in range or not?

I'd say about 1-2 seconds. The movement of the boat may be problematic. Also, it is difficult to see the laser in sunlight, particularly at 30' to 50'. This unit has a mode ,however, that can measure in real-time. The number will change as your target moves. This should be handy for your situation. I'd also try to take that measurement at night when the water is calm and the laser is bright. This is a great product, no regrets.Good luck.

Just timed it so everyone would know for sure and it is definitely 2 minutes. Mine was running low on batteries last week and that would account for it shutting off at 45 seconds.

open the velcro on the underside and up toward the neck is a switch to select how long it stays on for. it is probably still on "try me". you can choose 15, 30, or 45 minutes....or "off"....also important to know!

stays on about 15 seconds, it can also be set to just stay on until you turn it off

That depends on the setting. I've never had it on long enough to go out. I usually use it on the brightest setting and have had it last >90 min without dimming. I believe the manufacturer states that it can last 2 hours on that setting. Lower settings will obviously last longer.

I haven't really timed it, but I would say 4 or 5 hrs.. I really like it so mauch better than the huge one that came with the camera.

I haven't exactly timed it, but it doesn't stay on very long. I'm going to guess 20-30 seconds.

I think its lasted ten hours. Then it'll start blinking rapidly light blue for a minuet and shut off. I usually have it on during work continuously.

Quite a while. Can't give you an exact amount of time. Works great as an IR source although you cannot concentrate the light like a Torch , but then it's less than half price. Really good product!

I want to say maybe 5-8 min, I've never really timed it! Ours is set to come on at 7, so it's usually made by the time I get up. When I've forgotten to set it to "auto-on" I just turn it on before I go out with the dogs, and it's almost done when we get back in, so not long at all. Still love this machine!

The laser is only on momentarily when the firing pin strikes the back end of the Laserlyte laser trainer. I had no issues with the battery draining prematurely.

The light will stay on for 35 seconds. New movement after 35 seconds willreactivate the light.

The laser and the battery life, most importantly, the battery life. The old model lasted a couple hours tops.

It stays on. This is a very intelligently designed and well built laser level. Small and convenient. An excellent addition to your toolbox. Hope you enjoy it as much as I do. Dr. J.
