is this neutral buoyant, does it float above the diver for max visibility ?
MIKE M
The light floats and is relatively easy to see.
HARVEY C
It takes two relatively hard-to-get N batteries. The batteries are a very loose fit in the light, so they rattle around and may not make proper contact. I wrapped heavy paper around them to fill in the gap. However, the light still turned on only intermittently. I finally just threw it away.
I also would have preferred a floating light. I don't think this one floated.
I now use a very cheap tank flasher that floats and automatically turns on in water. It's totally sealed, and must be replaced when the battery dies. I just leave it attached to my first stage all the time.
GEORGE A
It floats a bit. I tie it to my tank, it then is slightly above the valve....everybody sees it! I use two of these ....everyone know that I am the one with two lights.
TRENT H
It does float but is not as brite as I expected.
LEILA M
Seems pretty neutral to me
Shopper
the lens has become cloudy can the strobe be pulled out to allow the light to be cleaned?
GEORGE A
Not sure. Try it and see if you can get the strobe out. If it is cloudy, most likely water got into it. These units only last a year or two before needing to be replaced. I like them because thet are cheap, work well for a year or two, cost little to replace.
EDMUNDO R
I do not think so. When you separate the lens from the battery body, it seems like the led light unit is glued to the lens unit.
Shopper
Does it have "stay on" mode also or just flashing mode?
GEORGE A
It does not have a "stay on" mode. It is only flashing which is what you really want.
The object of this "tank light" is so that other divers will know where you are at night. note that I have had other brands of tank lights; but, this one seems to be the most reliable.
EDMUNDO R
It only has one mode and that is flashing mode.
BOB N
I believe it only flashes.
Shopper
what is the range on this for night diving?
AMMAR A
I've tried it twice during night diving. Visibility was terrible but was able to see the flashing led from approx. 6 meters away. With good viz no doubt it can be seen from a farther range.
SCOTT J
Of course it depends on visibility. With 40 feet visibility, I was able to see my fellow three divers to about 20 feet.
RANDALL S
That totally depends on the visibility....however this light is pretty good but not as good as some sticks....I got it because it's orange and I put three Orange (all different) lights on my 14 year old son so I can be sure to see him plenty good....took him on his first night dive in July in cozumel...visibility was good and I could see it probably from 30 to 40 feet away....not that I ever got that far away because I didn't and never would. at least no until he has many more ocean dives.
ADELCIO JUNIOR D
About 15 fts
MARK A
I can't say by the time I got a chance to try it it was no longer functional. The strobes they make on the other hand work great.
NICK S
That all depends on your local conditions. In Fla. or very clear waters with 75 ft +viz, you'll see it 30 or 50 ft away. But I bought a larger, more powerful one for up here in New York to attach to the tie-in line when wreck diving. Up here I'll use the Fire Fly as a tank light on a night dive.
Shopper
Is this bright enough to use as a strobe for North Atlantic wreck divinig? (i.e., to tie off on the anchor line.) If not, which models that you have are appropriate?
LeisurePro S
For emergency stobe you will need something stronger like Tektite Xenon Strobe 200 .For a marker light your choice would be fine
