SeaLife manufacturers two underwater housings for the Reefmaster Digital camera. The
SL111 and SL111DX. The primary difference between these two housings is the depth
rating. The SL111 is depth tested and rated to 100 feet (30m) and the SL111DX is depth
rated and tested to 200 feet (60m). The depth rating is printed on the front lens port
to help you distinguish between the two housings.
SeaLife Reefmaster Digital Housing (SL111) for DC100
• Depth rated and tested to 133ft. (40M)
• Made from crystal clear Makrolon
• Rubber grips - gray/blue slip proof, adds shock resistance.
• Two O-ring seals, one on body and lid.
• Optical glass lens port.
• Stainless steel hardware - corrosion proof.
• Simple 2-button operation (power and shutter/delete button).
The camera's 1.8-inch color LCD is used as your viewfinder which makes framing
your subject very easy.
There are only two controls, the Power button and the Shutter button. The clear case
lets you see the data LCD display on top of the camera.
The underwater housing has two O-ring seals. One O-ring is glued to the body and the
lid O-ring is Teflon coated and replaceable (suggested after every 50 dives.)

external flash and 3x macro lens
Use the SeaLife External Flash to enhance color and brightness. Water filters out light and
red/yellow colors resulting in darker, bluer images. The only way to prevent this from
occurring is by taking pictures at shallow depths (within 5' depth on a sunny day) or by using
artificial light, like the SeaLife External Flash. Another tremendous help is having less water
between you and you subject and that is accomplished using a Macro lens(see below) or wide
angle lens converter and external flash. The Macro or wide angle get you closer and the
External flash helps eliminate backscatter from particles in the water between the lens and
The External Flash easily mounts to the bottom of the housing. The flexible arm allows
you to direct the flash at the subject. Even two flashes can be mounted onto the
housing for an evenly illuminated and shadow-free image. This system blocks the built-in
flash and prevents backscatter. The flexible flash arms allow quick adjustments of
the flash. An optional Flash Diffuser can be snapped onto the flash head. This lets
you dial 3 different flash intensities, which is highly recommended for close-up shots
and reflective subjects.
The Macro 3x Close-Up Lens improves your picture quality dramatically and should always be used
for consistent quality as your best images are close. It has a convenient distance range from 2
to 4 ft/60 to 120 cm. The Macro 8x Lens is made for 14 to 16 inches/35 to 40 cm, and the Macro
16x for 8 to 9.5 inches/20 to 24 cm. The 8x / 16x come in a kit with the "telescoping Macro
Wand" for proper focus distance measuring with either lens, extend the slider for the 8x and
slide it in all the way back in for the 16x lens. The wand mounts to the standard tripod socket
and can be folded to the side for transportation. The SL970, a 20mm wide angle lens converter
reduces focus distance to 12" to infinity with 50% more field of view, so its great for getting
closer to larger subjects and still getting them all in the frame. All of the macro and wide
angle lenses are removable while underwater as they clip to the exterior lens port of the
