Is this a good laser for diving?

I'm on the hunt for a green laser for diving. So far this is the best thing I could find: Green scuba laser pointer

Is this a good deal? Is there anything comparable for a better price or anything that will actually work better?
 





I don't dive but there is lasers that are about 100-150 us dollars with a variety of color beams. Some of them are waterproof with warranties. I wouldn't spend that much on a 5mw laser lol get a 200mw waterproof greenie. U will save money and have more fun with it

That's what I thought as well. Only problem is I can't find a 200mw that is rated to 40m or better. If you can help out there that would be great.
 
I've never heard about diver specific laser. Put it in the bag I guess.
What's it good for anyway ? To point stuff to other divers ?
 
I can understand the need for a good flashlight, but what do you use a laser for in 40 meters of water?
 
Diving and lasers sounds like a bad mix to me - all those reflective surfaces swimming around :D
 
I film underwater for a living and it has several uses for me:

Getting another cameraman's attention. Flashlights can ruin someone's shot if you are flashing at them. A laser would be way less bothersome to someone who is currently filming.

I have seen people using them before and the fish seem to react to the beam and will chase it which cause a chain reaction and soon lots of fish start being very active. Kinda like sharks going into a feeding frenzy. This is very helpful for creating great action shots.

We film a lot of macro subjects and sometimes it's hard to point out to another cameraman where something is. This would be very helpful here.

I'd love to see that. Do you have a link to a video maybe? :D
 
Hmmm... interesting. This makes much more sense that my vision of 2 geeks in scuba gear reenacting a light saber duel in 120 feet of water. LOL

No you cant put one in a bag. The problem is if you put the laser in a bag the pressure would cause the tailcap to act all wonky an or fail completely. There may be better alternitives but a bag wont help :p.

Sorry don't currently have any good video but if someone can point me in the right direction to a good pointer I promise to come back with some sweet video in a couple weeks. There are however lots of videos on youtube of aquarium fish chasing lasers.

Yeah, I've seen a few of those videos on youtube. They all seem to be using red pointers and the fish are only chasing the dot though.
I was wondering if different beam colours would make a difference to the fish, and would red beams vanish underwater? Red is the first colour to disappear underwater from the spectrum isn't it? (or so I heard on a fishing program when they were giving a reason for using red line)

You are correct red is the first to go underwater. Green would be the best choice. The ideal scenario for me would be around large schools of fish (jacks, snapper, mackerel) with sandy bottoms below them. I can play with the beam on the bottom and they will attack it. This would draw in larger predators (sharks, barracudas, groupers, etc...).

Pretty sure IR would be the first to go under water.

I don't know much about laser pointers and IR in general but not sure why that would matter for what I'm trying to accomplish. Underwater you lose the ability to see red the deeper you go. Green would not be a problem.
 
It is not relevant in the slightest to what you are trying to do. Iman is an up-and-coming smartass. <---- This is Not A Compliment.
