The water casing is made by Canon while everything else is either Merkury Innovations (Targus) or some cheap brand that doesn’t even put the company name on their product. The battery is a cheap knockoff by CTA and the memory card wallet is probably worth $0.50 at a dollar store. There is some image recovery software but it looks like one of those “AOL Free Trial” disks (the website has ImageRecovery 3 for sale while the included software is just ImageRecovery). The tripod feels so cheap that I’m almost afraid to put my G9 on it while it’s extended at all. The USB SD card reader doesn’t look anything like the picture, which actually looks somewhat nice, but instead is a cheap, fat, clear plastic thing.

I’m not unhappy with the product, but that’s mostly because I have a water casing and a cheap battery backup. I’ll probably end up buying a better tripod and a better carrying case in the near future.

This is the best $30 I spent for this vacation! What fun to just snorkel with a digital camera. I leave my camera in the case almost all the time now, to protect from rain, sand, etc. while at the beach. This video is in Kauai, Hawaii.

FEATURES: Uses 4 “AA” batteries. All of my other camera equipment for this dive trip used “AA”’s and I didn’t want to have to deal with proprietary battery packs, so this was am important feature for the flash unit.
LIGHT-POWER: The SL-960D is a single-head strobe with a Guide number of about 17 at maximum power output. Professional U/W photographers almost always use dual-head lighting systems with Guide numbers of 50 or more, but this was out of the question for my budget. The “range” of the SL-960D, in which it gave best results, was 2′~4′ from the camera to the subject. The camera was a Canon A-620, a P&S with a pretty small lens and a maximum aperture of 2.8 (not really great light gathering power). A digital SLR with an F1.4 lens would probably have achieved better results from this relatively low powered flash gun. That said, I was able to get some really amazing stills on the 17 dives in which I had the flash gun mounted. When everything was just right, fish not moving too fast and at the “just-right” distance from the camera, clear water with no suspended particulates, and the optimal camera settings, the photos were better than I could have hoped for clarity and color. But, if the subject was beyond 5′~6′, the light from the flash gun was usually too dispersed and weakened to make much difference. In other words, this flash gun did a decent job within it’s design limitations, but don’t expect miracles. In all fairness, this was my first dive trip in which I took high quality U/W camera equipment; my lack of expertise and experience probably meant that I lost a lot of shots that a professional would have gotten with the same equipment.

The SL-960D unit is triggered by slave-strobe from the camera’s built-in flash. On about 1 in 20 shots, the SL-960D failed to fire or if it did fire, it was not synchronized properly to the camera shutter. With this in mind, users are recommended to take duplicate shots of important subjects, so “bad” shots can be deleted. The SL-960D has a dial to regulate power output, but I quickly discovered that the unit isn’t powerful enough to bother with “low” settings; I left it on full power for the rest of the vacation after the first dive.

I used 2000mAH NIMH cells in the SL-960D, and averaged about 60 shots per dive using flash; the flash never ran out of battery power on a dive. Build quality of the unit felt okay for the price. The polycarbonate housing and battery loading hatch are fairly thick and the hinges and locking latch feel like they are of reasonably good quality. The mounting plate and flexible arm worked well on the Canon WP-DC90 camera housing. The flex arm was easy to hold and provided a good grip for the left hand.

CONCLUSION: If your budget for an underwater flash gun is limited to less than $400, the SL960D is probably the best unit you will be able to afford. But, if you can afford to spend more, like maybe $1000~$1500, a dual head Sea and Sea or Ikelite lighting system offers a lot more power, which will enable you to use smaller lens openings and faster shutter speeds. NOTE: The SL960D is flash-strobe light for still photography, it is NOT a continuous-emitting light for videography.

First let me say that the “reviewer” Mark is very wrong. This case is rated at 40M and works excellently. I don’t understand how people can write such negative reviews when they haven’t even used the equipment – much less owned it.

I purchased this for a trip to the Carribean and used it both for underwater use (scuba and snorkeling) as well as for a protective case on the beach and for general use. It works flawlessly. The only *negative* is that when you use it above water in bright sunlight you must remember that the front lens element is not anti-reflective so you can get a lot of lens flare if you’re not careful. Underwater this is of course no problem.

The flash diffuser is also very nice and provides good coverage while removing the housing shadow that is apparent when you use the flash without the diffuser.

Really there’s nothing to complain about here. The housing allowed me to get photos I’d never have otherwise.

Additionally, you can generally tell from the photos whether the housings are rated for snorkeling (e.g. 5-20 ft) or scuba diving (80-150 ft) by the beefiness of the seals and plastic. Pricing for the lightweight snorkeling cases are under $100, too. This housing is pretty clearly rated for scuba.

It appears equivalent to the Canon underwater housings both in build and price (which I have used), but you get the added advantage of the superb low-light performance of the F30 inside!
