Scuba Diving in Lake Superior for 'Glowing rocks' sodalite

[Diverdon]

You'll need a UV light to find these. 365nm wavelength works best but the ones found on my OrcaTorch D900Vs (395nm) worked well enough for me to find them. Once I did I took them home and put them under better lighting and they really pop.

Hi Sam,

Glad to hear you liked the video. I'm enjoying the new software and will put out a couple more videos before the holidays.
Take care sir!

Haha, rub it in, Sam. I may just have to visit (impose). It's been known to happen...

But yes, the lake is getting quite cold. Last week I did two dives pulling buoys out of the Lake and my computer registered 31 degrees both times. Odd, but it felt every bit that cold. The Saturday prior, 34.

I'm fighting back by growing out the beard. Odd as it sounds, it really helps. It's almost a requirement for ice diving. Have you ever tried GL diving, Sam? It has its pluses.

Excellent video! Some really cool finds, too! I wonder if there's anything like that here in my neck of the woods....

Very cool. We started using UV lights a couple of years ago. Makes dive dives quite interesting.

It really does. Mind if I ask what lights you use?
Thanks,

I have no idea what you may find in Texas. The only way to find out for sure is to look for yourself. I added links in the description of the video to the product that I use to look for the stones as well as mounting brackets for surface shots. The flashlights are only rated to 6'(2m) and have a single o-ring so I wouldn't take it too deep, but perhaps it would be OK for snorkeling or shallow diving.
Do a little researching and you could learn a lot about rocks containing elements that react to UV. You may be surprised to learn that there is plenty of opportunity for rock hounding in your area.

To save you the trouble of going back to the video, here are some links. It's a fairly inexpensive endeavor.

If you find some, get some 1/2" PVC, one 5' length should do, a couple elbows and some brackets to make a display.
Brackets: https://amzn.to/2QKTXlw

If you intend to take digital photos you may need UV filters for your camera as well. It seems the sensor in many DSLRs, including my GoPro, are sensitive to UV and the photos can get washed out. Get a good UV filter.

Hope that helps.

I love black lights while diving. Being able to find such cool pieces underwater is just often.
