as others have posted, they don't know what they're talking about. here's what the Seal Check system actually does. Seal Check II represents the next generation in Gates legendary reliability by allowing confirmation of housing seals before entering the water – virtually eliminating water intrusion as a source of downtime and unexpected expense. History reveals the top three flood causes are damaged o-rings, rushed setup and unfamiliarity with equipment. With Seal Check II there is peace of mind ahead of time. A precise digital readout provides a clear indication of housing integrity -- giving you the go / no go decision -- and aids with troubleshooting should the need arise. The electric pump quickly pulls a measurable vacuum, all contained in a small Pelican case. Seal Check II is also available with an optional self-install kit for non-Gates housings, too. http://www.gateshousings.com/seal-check-ii/

GoPro's have a fixed focus, non-zoomable lens. Normally they shoot in 170o mode but you can change it to "narrow" (120o? - I believe) mode at some of the 1080P resolutions also. Your Sola's have a 60o beam width. ULCS sells a double GoPro tray/handles to mount your arms. http://www.ulcs.com/gopro.html$135 with the two handles though, they're $50 ea. Reef sells it and they ship internationally. http://reefphoto.com/shop/index.php?main_page=product_info&cPath=135_17&products_id=5579GoPro's have a unique mount. The current GoPro 4 Black only shoots 30FPS in 4K if that's a consideration. It does however shoot 1080P as high as 120FPS. The Black is supposed to be the best in low-light also. If you want to see what you're shooting, you need to add the $80 BacpacLCD to it, Or give up the 4K resolution and go with the Silver which includes one. I don't believe it's as good in low light though. But with your lights, probably not an issue.

Aditech Mangrove houses the Sony FS700 or AX100 https://www.aditech-usa.com/en/uw-still-digital-video/cat-238-1-16-134.html

These are the people that supply the corrective lenses many dive retailers like LeisurePro sell. (Aquatic Optics brand) IDK if they sell to the public. http://www.newportglass.com/aqucat.htm

Anyone know if Jill Heinerth is still teaching u/w filmmaking? She was at one time - maybe on an intern basis? http://www.intotheplanet.com/ Not Thailand though, South Florida.

It would have to be one of the Sony HDR-HC series or possibly an early HDR-SR series camera. The HC's are all tape based so might have better compatibility with your housings LANC. A little after that time period - maybe 2006? or so - Sony switched to their Multi-Interface Accessory Shoe and eliminated LANC. So none of the newer CX series cameras will work. Another consideration is that the HR series are quite a bit shorter than the PD-150. This shows the differences - http://www.dvinfo.net/forum/attachments/sony-xdcam-ex-cinealta/8506d1217498523-ex3-pd150-hc1-size-comparison-pic-pwmex3-size-comparison-001.jpg - the bottom camera is an HDR-HC1. Maybe there would be room enough for a small internal monitor up against your viewfinder.

You can't really if you bring all that other stuff, the DJI quad doesn't break down small enough since it's a solid body quad - only the struts/camera mount come off somewhat easily. DJI sells one for their complete system or there's this one: http://www.amazon.com/Professional-Cases-Phantom-GoPro-Accessories/dp/B00I8UCVZQ/ref=sr_1_11?ie=UTF8&qid=1397985066&sr=8-11&keywords=dji+phantom+case IDK about you all but I also carry regs, mask and a few clothes so I'll be checking mine.

In a mildly related post - see what Stan Waterman thinks of it - on the Aggressor over the Tibbetts off Cayman Brac. If anyone is interested, that's a Fatshark Predator system Stan is using.

There's also the new Sony 4K - supposed to ship next week. http://store.sony.com/4k-camcorder-with-1-sensor-zid27-FDRAX100/B/cat-27-catid-All-Advanced-Camcorders http://wetpixel.com/forums/index.php?showtopic=52255 Aditech and Sealux have both announced a housing for it. https://www.aditech-usa.com/en/news/13-new-mangrove-housing-for-sony-fdr-ax100.html http://www.sealux.de/en/

I've got it but the .pdf is too big to attach here. Send me a PM with your e-mail address.

True but wouldn't you think Sony would attempt to put their best demo footage on their website where they're trying to sell the camera? There's a lot more artifacting on any of their demos (at least the 6 I looked at) than the GoPro main page demo.

I just watched the video demo's and was underimpressed. http://store.sony.co...Sony_Action_Cam The extra 19mbps makes a big difference. Too bad because I sort of wanted one.

I think you'd need something a whole magnitude better than a GoPro - something that can take a beating based on the shock it will be subjected to. Is the concrete 100M deep? It will be dark and under a lot of pressure also so I don't think any consumer grade housing will stand up to that for very long. Plus if you mount the camera close enough so it's actually useful for the operator it will likely get hit by debris occasionally. You're also going to need a lot of light. Once you start tearing up concrete u/w it's going to create a tremendous amount of silt and clouds of dust/debris. Maybe something like this: http://rosys.com/oceanographic/mantis-ocean/ Or something from here: http://www.sea-viewdiving.com/diving_equip...rinecameras.htm You might also consider something 3D so the operator has a better perspective on what he's doing. http://www.sea-viewdiving.com/diving_equip...vdsp3dhires.htm google remote underwater video camera for more options. Maybe talk to someone who does similar work to see what they recommend. You should be talking to commercial salvors or oil-rig inspectors - not u/w videographers whose only concern is keeping their camera dry. Who are you renting (I assume) the demolition rig from? Don't they already have something they're using on it? Their operator must need to see what he's doing somehow...
