I just got back from a Christmas week diving Cozumel Mexico's Palancar Reef System, warm water average depth 40-60-100 foot in blue sky sunny or over-cast conditions. 60-85+ foot viz........oh yeah it was horrible. (grins) feel my pain.
This trip over 10+ dives I shot a ton of video footage using super awesome stellar Snake River Prototype SRP red filters and macro lenses, on different shoots +10, +14, +21 diopter multi stack macros on different dives. WOW. Super versatile and flexible configurations of equipment.

I use a Hero2 in a Backscatter flat port housing that uses 55mm threaded lens port, and Hero 3 Black. (Hero 2 is more my back up rig or if the wife would ever film.......sigh)
The Macro Lenses, WOW. Santa came through with a multitude of SRP products, and I'm blown away by their performance.
As with anything in life, you get what you pay for. Glass lenes > Plastic cheap stuff, and with the Bare threaded SPR Naked mount you can easily choose what-ever options you want, wet mount change on the fly.
With SRP's clip on "naked" filter/macro mount of 55mm thread, it was super easy to store extra lenses/filters in a BCD pocket and swap them on/off using numerous configurations..............SRP's CY red filter only, bare GoPro Housing with Twin SOLA 600 Lights, SRP Red Filter with SOLA Lights, or SRP's way cool multi-stackable Macro Filters.....................all during the SAME dive.
Macros: +10 diopter lens one dive, a +10/4 combo the next, then a +10/10/1 lens stack too. Very Very flexible.
I could focus within 2-3-4" of Arrow crabs, bristle worms, or bulb tip anemones getting down to a nano scale of resolution shooting in 1080P x 60 FPS, and 2.7K x 30 FPS.
Some people want to be a picture taker, others strive and yearn to become photographers. I like professional looking video, not washed out washed out blue blurry fish butt shots (oh those were the days shooting film........).
To keep things simple, I left Protune off, I don't like spending 150 hours of video editing color enhancing in post production for a 5-10 minute finished video............The SRP CY filter out of the box on a clear sunny day brought out vivid colors, without too much push or oversaturation unless I was in shallow waters, where I didn't have the Shallow Water SWCY filter on me as it was back in the resort hotel room.
It's awesome to have a common 55mm thread mount between the Backscatter Hero 2 and SRP Hero3 naked mount. SRP's filters and Macro lenes blew me away during the trip and as a 10 year experienced underwater photo/video guy (Yes I still use an OLY SP-350 still), I'm very very impressed with Snake River Prototypes versatile and flexible equipment.
I'm in the middle of editing footage now, see my work soon in the GoPro forum in a week or two or three (grins) Tight editing takes time, I don't produce second rate blue washed out crap like I used to 8-10 years ago, thanks to my new lenes and filter.
Trust me, this isn't an advertisement for SRP gear, but a very happy divers' endorsement compared with other Ikelite, INON lenses, Backscatter Filters, Fantasea Filters and other equipment I've used hands-on over 10 years of diving.
I've used tons of different wet mount lenses and filters in my time if you read my Sig line in detail.
It's not always the gear, but the person behind the lens that makes things work. But the Multi Stackable Wet Mount SRP Macro Lenses blew me away for their real-world up close performance, and that's incredible cool for a GoPro to focus 3-4" away and aiming the video camera RIGHT into a Turtles Eye, Arrow Crabs arms/mouth, Anemone Arm Textures, or Soft Coral Polyps to capture up-close ultimate macro detail.
I'll get some video posted up soon.........proof is in the pudding of end results not in some rambling text message, but if you're at all interested do yourself a favor and check out SRP's website to see if one of their many versatile solutions would work for you and your application.
