The camera techs
at Sub Aquatic have been repairing cameras
for over a decade and are prize-winning amateur
underwater photographers. Therefore we understand
the value photographers place on their images
and the importance of maintaining and servicing
the equipment needed to capture those images.
Thatís why weíre passing on these tips to
help keep your Sea & Sea equipment working
and, more important, keep you capturing unique
underwater images.
We recommend The New Guide to Sea & Sea by
Joe Liburdi and Cara Sherman and suggest you read
all Sea & Sea instruction manuals cover to cover.
If you have questions, never hesitate to call any
authorized service center. The more you know,
the better you shoot.
EQUIPMENT FUNCTIONS
Here are ways to check several of
the mechanical and electrical functions on cameras
and strobes.
- Testing TTL for Motor
Marine II-EX (Check before loading.)
- Install batteries, turn
strobe to TTL, and set aperture to 5.6
or 3.5
- Point camera and strobe(s)
at a nearby reflective surface. Fire
the strobe at least twice. A green light
on the rear of the strobe should illuminate,
indicating partial power firing.
- Block off camera lens
and fire. The strobe should put out perceptibly
more light without the green light illuminating.
- Middle green LED TTL confirmation
light inside the camera viewfinder should
mimic strobe indications.
- Testing Auto Function
for MX-10 (The YS-40 is an Auto
strobe and measures light through a
sensor, not through the camera.)
- Fire at f/3.5 at a nearby
reflective surface. Note degree of light
output.
- Fire again with finger
covering sensor. You should see a substantial
increase in light output.
- Film Loading
- Choose ASA/ISO 100 or
400 for the MX-1.
- Place film in camera,
making certain the rewind "teeth" fit
totally into the film canister.
- Pull film "tongue" across
the film guide to take-up spool mark.
- Gently place finger on
top of the film on top of the take-up
spool.
- Fire shutter once or twice
until the film encircles the take-up
spool, then close the door.

O-RINGS
Marine cameras suffer far greater
indignities than land cameras. Extremes of heat
and cold water pressure, and saltwater dictate the
need for rugged construction. The most crucial element
in protecting marine cameras is O-rings. O-rings
come in different forms and have different maintenance
demands.
- User O-rings are
those serviced by the photographer.
- Sea & Sea black O-rings
use regular silicone grease in a Sea & Sea
white-capped tube. Clean by wiping
off with a lint-free towel, then regreasing
with silicone grease.
- New blue O-rings
require grease in a Sea & Sea blue-capped
tube.
- Wipe O-ring clean, grease,
remove the grease and with it, the
accumulated particles; regrease.
- Wipe O-ring clean, dip
in clean water, stretch (not too much)
and "thrum" like a guitar
string, flicking off particle carrying
water drops, then regrease (not too
much).
- Factory O-rings are
interior O-rings and must be serviced
only by trained technicians.
MAINTENANCE
User error or inattention causes the
majority of camera floods. Follow these procedures:
- Pre-dive
- Inspect O-rings
for cuts or dents.
- Clean and lube O-rings
and inspect for lint or stray
hairs.
- Inspect channels
before mounting O-rings.
- Inspect assemblies
for frozen parts, like shutter release
or aperture knob.
- Clean optics and practice
installation of accessory (wide-angle
and macro) optics.
- Test and fire internal
and external strobes.
- Load film.
- Inspect, then
close all user O-ring areas.
- Install arms and trays.
- During the Dive
- To mount an accessory
lens, align the yellow dot on the lens
with the white mark on the camera body,
and then turn the lens clockwise until
it clicks in place.
- On the Motor Marine
II-EX and Mx-10, flood the area between
the camera and accessory lens and check
for trapped bubbles or sand.
- Periodically check the
accessory lens position.
- Check viewfinder for
LED lights.
- Check strobe position.
- Avoid "levering" macro
framers.
- Watch for suspicious
bubbles.
- Post Dive
- Be leery of fin and
swim ladder "bumps". This
is the usual way of losing accessory
optics.
- Stay with camera, or
hand to reliable dive partner, while
reboarding boat.
- Never allow salt
water to dry on camera or lens; this
leads to salt-packed O-rings. Keep
wet until you get to fresh water.
- Remove dirt, mud, sand,
and other debris from the surface of
equipment.
- Rinse and flush. Hand
flushing for one minute in fresh water
equals a 24-hour soak.
- Never leave gear alone
in a rinse bucket; other divers and
ship movement can easily damage it.
- Never use alcohol, benzene
or thinners to clean camera body; such
solvents can damage the plastic case.
- Dry:
- Dry thoroughly with
a clean, dry, soft cloth.
- Pat dry optics;
evaporated water can discolor the
lens coatings.
- Do not use a compressed
air line for drying unless it is
below 70 psi or you risk blowing
water past your O-rings, as well
as into any open camera equipment
nearby.
- Rewind film. This is
automatic on the MX-10 at the end of
the roll, but must be lever activated
on the MMII.
- Dry yourself, your hair,
and remove torso gear; these can drip
water into cameras.
- Open camera downwards
so water from user O-rings doesnít
fall into camera. (This single action
can save your camera from hundreds
of dollars worth of damage.)
- Be ready to catch falling
film.
- Clean and inspect channel
O-rings. (This other single action
can save your camera from hundreds
of dollars worth of damage.)
- Just changing film?
Pull, clean, relube, inspect,
O-ring and channel, and replace back
door O-ring. Separate camera from tray
and arm, as these trap water.
- End of dive day?
- Remove all user
O-rings. Clean, inspect, grease, inspect, reinstall.
- Check battery power.
- Gently polish optics
clean.
- Install fresh film
and, if necessary, batteries.
- Reassemble camera
in a relaxed atmosphere, checking
each O-ring for debris.
- Annual Maintenance. Performed
by techs at factory or authorized service
center. Sea & Sea recommends annual
inspection and testing with a full service
every two to three years. (There are
16 O-rings in a MMII, less in the MX-10
that needs to be inspected or replaced.)
- Storage
Never allow water
to dry on the camera. Never expose
the camera to direct sunlight or
excessive heat because it can damage
the internal electronic mechanism.
Sea &Sea cameras should remain
within a temperature range of 40° C/104° F and -5° C/23° F.
Short term (for less than
two weeks). User O-rings and batteries
can be left in the camera.
Long term (for more than
two weeks). Remove batteries, and
user O-rings. Place in plastic
bag and rubber band the to the
camera body. This is also the procedure
for airline travel.
FLOODS
Even with the best maintenance, a
flood can sometimes occur, but they are not always
disastrous.
- In-water Flood, indicated
by small amount water discovered when
camera is opened.
- Turn all controls to "OFF" to
cut off destructive electric current.
- Turn Nikonos V to "M".
- Return to the surface at
a safe pace.
- Minor Flood, indicated
by small amount of water discovered when
camera is opened.
- Determine if water penetrated
from door, diver, or vacuum created
by opening the camera, or a correctable
problem, like hair or sand on the back
door O-ring. If so, correct problem
and Q-tip off moisture and let dry.
- If the leak isnít correctable,
as from a damaged part, dry, set aside
and donít use.
- Partial Flood, when water
has partially invaded the inner electronic
workings of the camera.
- Remove batteries and
film and, if wet, discard.
- If flood is in only
one portion, soak only that area in
fresh water.
- Place 18 inches away
from blow drier on low heat
and dry for two to three hours. (If
camera becomes too hot to touch, blow
drier is too close.) Or place in an
engine room for a day or two.
- If camera still works
and cause of flood has been rectified;
you can continue shooting but send
to technician as soon as possible.
- Biblical Flood, when
a goldfish comes swimming out.
Follow steps C1 through
3 above, and then place in a plastic
bag and ship to a technician ASAP.
- Flood of Nikonos-adaptable
lenses, where a quantity of water
intrudes past the front or rear lens.
- Flush thoroughly with
fresh water.
- Do not allow drying.
Put in plastic bag and send to a tech.
With proper care, maintenance,
and pure heart, your Sea & Sea equipment will
bring you years of exciting underwater photography.
