Hey, all you Aquatica S2 guys, if you install the accessory cold water grip on the housing (James, theses are the one on your Kodak Housing) it allows the battery tray to clear the grip since they are smaller and don't recedes as much as the cast grips normally furnished with the housing, theses are machined and have a knurled patern they can also be supplied with a quick disconect for hand held flash situation. Well wearing 7mm of neoprene on most dive make's you discover theses little details. The batteries on the S2pro are it's weakness and are high maintenance, so I got three batterry tray and can swap card and batteries in a jiffy since I've done that switch.
I have both the S2pro and D100 and their associated housings, still find the out of the box file better on the Fuji, still prefer the ergo and mentallity of the Nikon, BTW if you can get the new Hyper utillity for the S3pro get it, it makes the older version for the S2 look like crayon base technollogy, much easier and way improved. Now if I can only find a way to get an S3 under in something else than a Ziplock bag
