  1. A short video on the ongoing Weeki Wachee Springs cave exploration in Florida that hopefully helps to provide insight into the "hows" and "whys" of this project. This cave system is the second deepest in North America and is absolutely breath-taking! Moreover, it's a cave that takes quite a bit of effort and teamwork to explore and document....
  2. Looking for 1 or 2 strobes for use as slaves. Anyone looking to sell?
  3. Here is some additional footage of the lights from another cave system. This was shot the day before and was our first use of the lights. Darker walls and more fine sediment in the water... Cheers, Mike
  4. Yes, those are the ones being used off-camera by the other diver. We are going to work on a syntactic foam collar for these big lights as they are just too heavy (i.e., -2 pounds each) to effectively extend on arms. We ran burn tests and got 69 minutes on full before the LED blinked red (approximately 5 minutes battery life left), so a little bit more than the stated specs.
  5. Information on the lights used can be seen at the end of the clip. Two 2500 lumen video lights were used on camera and two 15000 lumen lights were held by the other diver off camera. We plan to shoot additional footage under different conditions, including open water coral reef and the like.... Cheers, Mike
  6. Footage of test dive in Indian Springs cave system south of Tallahassee, Florida, on Sunday using new video lights supplied by Bigblue Dive Lights (http://www.bigbluedivelights.com/). Two 15000 and two 2500 lumen lights used in footage. Video was shot on Canon 5D MKIII using 17-40 mm f/4 L lens at 1600 ISO with Technicolor CineStyle Profile. **NATIVE TEST FOOTAGE -- UNTOUCHED AND UNGRADED** http://youtu.be/5Keto1o2tFQ Enjoy! Cheers, Mike
  7. Yeah, and the wheels are obviously up and flaps extended. Odds are the guy survived the ordeal. Diving 10/50 diluent - had planned for a short 20 minute bottom time but conditions were so nice it was closer to 30...total run time was 90 minutes. Cheers, Mike
  8. Late last year a submersible groundtruthing multibeam sonar survey targets stumbled upon a WWII-era Grumman Hellcat resting in 245 feet of water off Miami, Florida. A few days ago we went out to dive the site and get some good video of the aircraft. You might also notice a lionfish or two in the footage ;>) To date, the U.S. Navy has not confirmed the actual airframe or the circumstances of the loss, however, it was likely a training accident. Footage was shot with a Canon 5D MKIII with a 17-40mm lens and twin SOLA 1200 lights. Due to hazy surface waters, it was quite dim at depth so I had the ISO jacked up a bit. Be sure to watch in HD. Cheers, Mike
  9. I was shooting in 1080 60fps mode, and approximately 45 minutes of footage is about 11GB. So, yes, you will eat up some memory in a hurry, especially if you use any of the higher-resolution modes. I am including a link to some footage from my first dive with the mounted GoPro to give you an idea of how it worked out. It was on a ball mount on top of my camera housing connected to another ball mount threaded into a tripod mount on the GoPro to clear the sync cords and also allows me to lay it flat when I have the strobe arms folded and stowed. The FOV of the GoPro is less than the FOV of the 15mm FE I was shooting with on this particular dive. I just need to angle it down a few degrees, particularly when shooting things up close. The constant moving as I check the LCD screen, adjust strobe arms, and strobe power settings while shooting stills is pretty obvious, not to mention all the strobes going off...but I think it definitely can come in handy on some dives... Cheers, Mike
  10. I recently used my Hero3 Black mounted on my Aquatica housing on a cave dive and just let it run while I shot stills. I got right around 55-58 minutes if I remember correctly (shooting 1080 wide at 60fps). I was not generally shooting closeups, but did note on one series getting diver shots that I have to angle the gopro down a bit (versus shooting straight ahead) to avoid cutting off on closer in subjects. I used twin SOLA 1200s (mostly on low just to help with autofocus in the cave) and it performed well, but obviously suffered in quality due to low light. When I cranked them on high, the footage looked pretty nice. Again, I did not have the lights optimized for the gopro but the housed camera, so the fall-off and lack of coverage in the middle was noticeable as I did not have things aligned for the gopro. I think in openwater it would work reasonably well to get "filler shots". If you shoot a lot of stills, the firing of the strobes obviously impacts the footage and is annoying, plus you can really hear the shutter tripping. But as a "set it and forget it" type of camera, it works ok... Cheers, Mike
  11. Hi Phil- It is not uncommon to see hooked fish as they are large fish that have the ability to take a bait (depending on the size) like other fish. Since they are the big boys on the block and opportunistic feeders, they commonly go after hooked fish as they are reeled to the surface, sometimes becoming hooked themselves. And there is also ongoing research (permitted activities) where fish are hooked, brought onboard a vessel, and biological samples are taken, fish are tagged, etc. The important point is that this shallow-water grouper species is robust enough to take it and either part a line on the wreck or bottom or unhooked or line cut at the surface by the angler, and have a very high survival rate. The protection prevents hooked fish from being retained, fileted, sold, etc. Obviously, given the population rebound, the protection has been very effective. Cheers, Mike
  12. Harvest and possession of goliath grouper has been prohibited since the early to mid 1990s over here, and they have made a remarkable comeback... Cheers, Mike
  13. Average fish are probably 200 pounders, with some ranging up to 400 pounds. Here is a link to video from yesterday's dive: Cheers, Mike
  14. A couple pics from yesterday's dive off Boynton Beach, Florida, on the tail end of the goliath grouper spawning aggregations... And a video clip from last week's dives off Jupiter, Florida, for more aggregation and bait ball action... Cheers, Mike
