MASKS Snorkels Fins Suits BCs Tanks Regulators Instruments Physics Physiology Safety Places Sealife GoPro HeroThe GoPro phenomenon: what the world-beating little 1080p vidcam can (and cannot) do (by Conrad Blickenstorfer; most video and stills by Carol Cotton)Update November 2011: Days after we released this comprehensive review of the GoPro Hero, GoPro announced the even more amazing Hero2 with a faster processor, additional video and still modes, a new menu system and many other improvements. At DEMA 2011, GoPro then also announced an underwater housing that will address the blur issues we're discussing in the below review.October 2011 -- According to IDC, pocket camcorders were a US$2 billion business in 2009, with almost 14 million units sold in 2010. At ScubadiverInfo.com, we've reviewed several versions of the innovative Liquid Image video mask, the impressive little ContourHD, several versions of the now defunct Flip, and other small and compact cameras that record better video than the most expensive broadcast class equipment could not too long ago. Yet, until a recent conversation with the folks at Ambarella (more on that later), I was actually unaware of another contender in the pocket camcorder class that initially had a cult following and now is taking the world by storm: the GoPro. When I first got a GoPro, I was quite impressed with the small size of the camera (2.3 x 1.6 x 1.2 inches -- about the size of a matchbox) and certainly with all the included mounting hardware, but the GoPro didn't seem particularly elegant or high-tech. So, of course, I had to research this whole thing in more detail. The result is this rather lengthy report, and several dive trips that took us thousands of miles from home, and several hundred miles offshore.Who and what is GoPro? GoPro was started in 2002 by a surfer who wanted to have a camera to take along surfing. The name came from many a surfer's wish to "go pro," and "hero" stems from making people feel like heros when they could record and show their stunts. The original GoPro actually still used film, even in 2005. The second did silent 10 second digital video, the third had an SD card slot and 3 megapixel, the fourth, in 2008, had a wide angle lens, could do 5mp stills and VGA video. Then came the big step to high definition video and today's HD Hero 960 (960p video) and Hero (1080p video).Technology, however, is only part of the GoPro story. The real innovation was all the mounting systems the company made available. Starting with surfing and paddling, auto racing quickly followed, and that required different mounting. Then it was helmets, ski poles, motorcycles, and finally general outdoor sports. The ready availability of mounting brackets and systems, combined with the small boxy form factor, meant that the GoPro camera was used in very innovative ways, which brought a lot of publicity, which made it even more popular in many high-profile applications. The Discovery Channel uses it for "Deadliest Catch," and National Geographic, LucasFilm, or you can watch incredible footage of a race car barreling up the Pikes Peak hill climb, setting a world record (see here), and so on. The GoPro 1080p video cameraThe GoPro is almost a paradox. We expect advanced technology to come in spectacular, expensive packages, yet the GoPro is anything but. The little matte-silver plastic housing is very basic, with just two buttons, and no display other than a tiny black & white status LCD. There's a mini-USB port, and two TV-out ports, one standard, one HDMI. That's it. The box, however, did come with a lot of stuff. There's lots of mounting hardware, and I mean LOTS. There are cables. And the GoPro even comes with a waterproof housing. Yes, the housing is included in the basic package. So you get a 1080p HD video camera with plenty of accessories and an underwater housing good for 180 feet for less than you pay for a compact camera's underwater housing alone!Below you can see what all comes with the GoPro Helmet Hero package:Operating the camera isn't as simple as using a conventional digicam. That's because the GoPro doesn't have any controls other than the two unmarked buttons. There are no icons, there's no zoom, no playback button, nothing of the sort. Changing settings pretty much requires having the instructions next to the camera so you can decipher the cryptic codes for the 15 or so settings. Nothing is obvious or intuitive.I started playing around with the GoPro, and the video was terrific. And the still shots, too, were much better than I had expected from a simple 5mp CMOS imager. The very wide angle lens makes for a fisheye view with a cool in-your-face action effect.There are several recording modes, depending on card capacity and intended use of the video: Full HD - 1080p 30 fps (1920 X 1080 pixel, 127 degrees)Tall HD - 960p 30 fps (1280 X 960 pixel, 170 degrees)HD - 720p 30 fps (1280 X 720 pixel, 170 degrees)HD - 720p 60 fps (1280 X 720 pixel, 170 degrees)WVGA - (848 X 480 pixel, 170 degrees)Bottomline: the GoPro Hero sure looked like a terrific addition to the review gear we take along on scuba trips. Expectations were high.Our underwater experiences with the GoProIslas Revillagigedos (Socorro Islands), MexicoWe first took the GoPro on an 8-day expedition to the Islas Revillagigedos, a remote group of islands about 250 miles south-west off Cabo San Lucas on the Pacific coast of Mexico, and one of the most remote places you'll ever see. Exclusively reached via liveaboard vessel, the islands are not a group as much as four random peaks of rock poking through the surface of nowhere more or less in the same general vicinity.Among divers, Socorro is famous as a remote destination where one can see sharks and, more importantly, giant manta rays, also known in some languages as devil fish. Our above-water video was excellent, but 20 minutes of recording giant mantas, pretty much once in a lifetime footage, was blurry and out of focus, all of it. That was a major bummer as we'd left other video gear behind to give the GoPro a shot, and it let us down because someone didn't think the housing optics through. The picture below is representative for what we got. It looks halfway decent shrunk to this small size, but the full-size version is totally blurry and out of focus. As was all underwater video. Given our majestic subjects, and how rarely you see them, that was quite frustrating.We analyzed everything, wondered what we might have done wrong, examined any possible settings, then tried again. Same result. Blur, out of focus footage of sharks and giant manta rays. We tried several more times, and, adding insult to injury, the GoPro's already somewhat marginal battery conked out, yielding no more than a few minutes per charge towards the end of the voyage. Not a good start for the GoPro.We did, however, get enough video for a decent movie of the trip. Note the huge difference between above water and underwater video:Back from the trip we instantly went on eBay and ordered a real battery charger (the GoPro charges via USB cable, a notoriously unreliable charging method) and two extra batteries. That solved the power problem.Cancun and Isla Mujeres, MexicoWe then took the GoPro along on our next product review dive trip, this time to Cancun where we dove the wreck of the 165-foot C58 mine sweeper in strong currents. The GoPro was certainly much more handy than the big and bulky camera and video gear we usually take along. Unfortunately, the result was the same: blurry, out of focus video. We encountered two other parties who also had GoPros and loved them for sky diving and off-roading. But under water, both had the same problem: blurry scuba video. We didn't even bother taking the GoPro on a whale shark snorkel expedition off Isla Mujeres where we saw about a hundred whale sharks in crystal clear 84 degree water. Towards the end of the trip we saw a guy who had a GoPro with a large third-party dome on its housing (see below). He said it fixed the blur problem underwater.Fixing the GoPro's underwater blur problemOnce home I did what I should have done in the first place: I googled the problem. Lo and behold: the GoPro's underwater housing cannot be used for underwater video! Why? Because the housing's curved dome lens keeps the camera from focusing underwater. It just can't. Ever. Apparently that's been a known issue pretty much ever since the GoPro Hero came out. Scubaboard has hundreds of posts about it. And there are a number of fixes. In essence, you need a flat dome.The big question is why GoPro does not alert customers to this on its website or on the package. I mean, how can a company advertise a waterproof case, good for 180 feet, when YOU CANNOT USE THE CAMERA UNDERWATER BECAUSE IT WON'T FOCUS?!!? That is more than just an omission. It is really unacceptable. I really, really would have liked to know ahead of time that taking the GoPro to film one-of-a-kind shots of half a dozen giant mantas would not work.So I researched available third party solutions, and here are some of them:Snake River Prototyping offers the BlurFix adapter, the most professional looking solution of the lot. It's a precision-crafted aluminum adapter that leaves the GoPro housing's existing dome intact, but puts a flat-plate glass lens in front of it. This, of course, means a sealed air space that's potentially subject to fogging. SnakeRiver guarded against that by including a rounded groove for ceramic desiccant balls. The dome can also accommodate screw-on color filters to adjust for underwater conditions. There's a bit of vignetting in the 960p mode, none in all the others. The adapter with a clear filter costs US$77. Mounted on a housing it runs US$139. Eyeofmine.com offers a flat lens with a custom dome that replaces the stock curved lens. Eyeofmine does the modification and sells the complete standard or wrist housing good for 100 feet (US$79) or 200 feet (US$99). The glued-on fix is not pretty, looks more like a science project, and the acrylic lens is prone to scratching, but the fix definitely works and there isn't any vignetting in any of the recording modes other than a bit in 960p.aquapixs.com offers a glass (44 Euros) or plastic (30 Euros) replacement lens for the GoPro. The plastic lens is made of Makrolon and is said to be good for 190 feet. You simply unscrew the dome on your housing, replace the stock dome lens with the flat one from AquaPix, and you're done. There is, however, vignetting in all modes except R5 1080p. Mako offers the MAKO Flat GoPro Housing Lens for just US$21.95 for those who don't mind the do-it-yourself approach. You simply replace the stock lens with the one supplied by Mako that's supposed to be totally vignette-free in the 1080p R5 setting. In lower resolution settings, the camera viewing angle is increased and the outer edges of the housing lens become visible in video and images.Sartek offers a full replacement housing with a elegant black replacement dome ring and a glass lens. US$100 for the housing with lens. It's advertised as good for 240+ feet and free of vignetting in the 1080p R5 setting. There's also the Oculus flat lens; it consists of a flat plastic lens and a replacement dome ring. It is sold via eBay and usually costs about US$35. It's advertised as good for 230 feet and free of vignetting in the 1080p R5 setting.The above are by no means all of the solutions. Do note that simple replacements of the stock rounded lens will result in vignetting (i.e. the camera sees part of the flat housing lens, which results in rounded corners) in settings other than the 1080p R5. If you intend to use the camera in all of the recording modes, you need a fix that replaces the entire dome. We opted for the EyeOfMine solution. It arrived very quickly and testing in the pool showed a huge difference compared to the standard housing. Video and pictures were now in focus underwater. Click on the picture below for a larger version.Can the GoPro see underwater now?Coronado Island and Wreck Alley, San DiegoWith the apparent solution at hand, we were eager to give the GoPro another shot, and it came in the form of a trip down to San Diego where we boarded Waterhorse Charter's Humboldt for the one hour 20 minute ride to the Islas Coronados just south of the border in Mexican waters. These are stark, but beautiful islands, uninhabited, and similar to the better known California Channel Islands. We dove "Lobster Shack," a shallow, rocky dive site with sea lions galore. Down at just 25 feet or so, we were literally mobbed by curious sea lions, pups all, who darted all around us. It was a mesmerizing experience, and, finally: sharp underwater video!!The next two days we were diving off San Diego, in what's called "Wreck Alley." The main attraction is the 366-foot wreck of the Canadian destroyer HMCS Yukon that's laying sideways in about 100 feet of water. This was a tough dive as the "red tide" (a natural algae/plankton bloom) made the top 20-30 feet of water brownish-opaque. Underneath, the water was a bit clearer, but there was virtually no light. At the wreck, visibility was perhaps 5-10 feet, and the water temperature was just 55 degrees. We had attached the GoPro's wrist-mount housing to a makeshift video light by using one half of a camera lighting arm (see above). There was so much particulate floating around that lights were nearly useless. We still managed to get some video out of the GoPro, and we certainly appreciated the handy size of the rig. BacPac LCD displayOne of the problems with the GoPro, of course, is that it doesn't have a display. Thanks to the wide lens angle that's not too much of a problem as one tends to get the proper footage anyway. And many GoPros spend most of their recording time mounted on something, like a race cars or skateboard, where aiming isn't much of an issue. Me, I still missed an LCD to see what I am actually recording, and so, apparently, did enough other GoPro users for the company to release a "BacPac" LCD module for the GoPro in September of 2011. We ordered one the day it came out, and here's how it looks and works:
