I. Safety Warnings

Always discharge flash before opening the waterproof door, by moving

the power switch to the “TEST” position, and then to the “OFF” position.

This will discharge the high-voltage electricity stored in the flash.

If foreign objects or water has entered the flash, discharge and turn off

flash. Continued use in this state may cause fire or electrical shock.

Contact the SeaLife service center for repairs.

Do not attempt to access the electronic circuitry for any reason. The

internal electronics uses high-voltage components that may result in

severe electrical shock.

The On/Off/Test switch contains a powerful magnet. Keep away from

compasses and electronics to avoid magnetic interference.

Do not expose flash to heat or direct sunlight for prolonged periods of

time.

Observe all SCUBA dive safety rules and control your buoyancy at all

times. Consult your dive instructor for dive safety questions.

called Great Pictures Made Easy.

II. Introduction

Thank you for purchasing the SeaLife Digital Pro Flash. Novice

and experienced divers alike know that the deeper you dive, less

light penetrates the water. While this descending drama adds to

your excitement as a diver, you will find that it also challenges

you as an underwater digital photographer.

The water filters out red and yellow so everything looks blue. The

fact is that reefs and fish are bursting with color. A powerful

underwater flash system is the best way to restore the lost colors.

Without Digital Flash With Digital Flash

This instruction manual will guide you through all the essential

information on how to operate and care for your flash, and tips

on capturing some of the best underwater pictures of your life.

III. Preparing your camera

Become familiar with how to operate your camera. Refer to your

camera instruction manual for information on how to adjust the

settings described in this manual. Here is the basic camera set-up for

SeaLife and most other popular digital cameras and their housings.

1. Insert blank memory card. It’s good practice to regularly

format memory card, but be careful, because this will erase

all images on the card.

2. Make sure your camera battery(ies) are new or freshly charged

before each dive.

3. Set SeaLife digital cameras to External Flash mode

4. For Non-SeaLife camera’s, do this:

a. Set ISO to 100 (or less if available) but not Auto.

b. Set White Balance to “CLOUDY” for better color.

c. Set camera’s flash to FORCE ON.

d. Select the highest image resolution.

e. Some cameras offer manual shutter and aperture controls,

which is recommended for advanced photographers only.

5. Inspect and clean camera housing and main O-ring in

accordance with the camera/housing instructions.

6. Insert camera and seal the housing.

7. Take a test picture to make sure the camera’s flash fires.

IV. Preparing your flash

Unlock the latch by sliding

down the safety lock.

Lift the latch and open the

waterproof door to access the

battery compartment, pre-flash

setting, and auto mode setting.

Important:

• Make sure the flash and you are perfectly dry before opening the

waterproof door.

• Open the waterproof door with the door pointing down, so any

water trapped around the o-ring does not drip inside the flash.

Insert 4 new or freshly charged AA batteries. Open the battery

compartment cover and insert batteries according to the polarity

markings above the battery compartment.

Set the Pre Flash switch to the “0” position for all SeaLife cameras.

For non-SeaLife digital cameras, set switch to the #4 position to

start. More information about finalizing the Pre-Flash setting for

NON-SeaLife cameras is provided on page 19 of this manual.

What is a Pre-flash?

Most digital cameras have one or more pre-flashes to assist in

autofocus/auto-exposure setting of the camera. The Pre-Flashes

occur before the camera’s primary flash fires. The Pre-Flash

Setting switch tells the external flash how many pre-flashes to

ignore before firing. For example, if your digital camera has 2

pre-flashes, you would set the Pre-Flash Setting switch to 2. The

external flash will now ignore the two pre-flashes and fire on the

third primary flash. SeaLife cameras do not have a pre-flash when

the camera is in External Flash mode. More information on how

to make the correct pre-flash setting for your non-SeaLife cameras

is described on page 19 of this manual.

Pre-flash cancellation settings

(continued)

Switch position Description of setting

0 Cameras with no pre-flash

For all SeaLife cameras

[Camera set to Ext Flash mode]

1 Camera with 1 pre-flash

[and cameras with rapid-fire pre-flash*]

2 Camera with 2 pre-flash

3 Camera with 3 pre-flash

4 Camera with 4 pre-flash

*Note: The #1 pre-flash setting works with cameras that use 1

pre-flash or a rapid-fire pre-flash system because it has a built-in

50 millisecond delay between the first pre-flash and the primary

flash.

More information on how to calibrate the pre-flash setting for

your non-SeaLife cameras is described on page 19 of this

manual.

Set the Auto mode switch to the “1” position for all SeaLife

cameras and “4” position for all Non-SeaLife digital and film

camera’s. More information about the Auto mode setting for your

NON-SeaLife camera is provided on page 20 of this manual.

What is the Auto mode?

Auto mode will automatically control the brightness of the

external flash and help you to achieve optimal image exposure.

When the external flash fires the light sensor located in the front

of the flash will instantly measure the light reflecting from the

subject. If it senses too much light, it will quickly stop the flash

and prevent the image from being over-exposed. There are 4

possible Auto mode settings. settings. One of the four settings will

be best depending on your camera type. The #1 setting will result

in slightly less powerful flash brightness and #4 will result in a

more powerful flash brightness. More information on how to

calibrate the Auto mode setting for your non-SeaLife camera is

described on page 20 of this manual.
