Thank you for purchasing an Ikelite SUBSTROBE. Ikelite brings 40 years of underwater photographic and lighting experience to the strobe market. Ikelite Substrobes are designed and built in the USA by Ikelite to suit both the professional and the amateur photographer.

DDSS112255 SSUUBBSSTTRROOBBEE ______________________________________________________________________________________________________

The Ikelite DS125 strobe combines high intensity output and wide coverage angle in a compact, versatile design. This strobe features 110 watt-sec. intensity and covers a full 100° using the diffuser. Special soft-lite reflector provides rich reds, oranges, and warmer flesh tones.

The Ikelite DS125 strobe is preflash compatible and operates with both traditional film cameras and digital still cameras. Multiple firing modes are featured, including TTL/Auto exposure. Add the optional Ikelite DS Sensor #4100.5 for wireless TTL/Auto slave capability with select cameras or the Ikelite EV-Controller #4100.6 for 10-manual power settings.

The DS125 electronics are safely sealed separately from the battery pack. The industrial grade NiMH batteries recycle in an incredible 1.0 seconds and the NiMH pack is easily interchangeable with a spare unit. When in the “

When the switch is rotated to the TEST position, the fuel gauge on the side of the strobe will display 0, 1, 2, or 3 red LED lights indicating the remaining charge in the battery pack (see below). A fully charged NiMH pack will provide at least 250 full power flashes and all 3 LED's should light. When no LED's are illuminated, then the battery capacity is low and you may have less than 36 full power flashes remaining. For general guidelines, refer to the following list:

• 3 LED’s - above 75%

• 2 LED’s - above 50%

• 1 LED - above 25%

• No LED - less then 25%

Some digital still cameras feature a small built-in flash a sync cord for an external strobe. Most of these cameras fire their built-in flash more than once while taking a flash picture. This happens so fast it is difficult to see, but the preflash helps the camera determine focus, exposure and color balance. After the preflash, the camera’s built-in flash then fires to illuminate the subject and the picture is taken. For the external strobe to provide proper exposure, it MUST be preflash compatible to duplicate the preflash sequence. The Ikelite DS125 strobe is a

Most newer cameras and strobes feature TTL/Auto exposure, which automatically compensates for aperture, distance, extension tubes, and filters. Considering the wide range of apertures and subject distances, select the TTL/Auto exposure mode to easily control balanced lighting and close-up photography.

When the strobe fires, the camera reads the light and automatically signals the strobe to turn off when the exposure is correct. Both the strobe and camera must feature TTL/Auto exposure compatible electronics. The appropriate TTL sync cord or optional Ikelite DS Sensor is required to relay the TTL/Auto exposure signal from the camera to the strobe.

Please review the "Compatible Camera" section on the previous page for additional information.

The Ikelite DS Sensor provides auto exposure functions through slave sensors enabling the Ikelite Substrobe to be moved freely and positioned virtually anywhere. The DS Sensor connects only to Ikelite DS Substrobes and detects when the light from the TTL strobe connected to the camera starts and stops, and automatically signals the Ikelite Substrobe to start and stop in sync.

Many digital still cameras feature a small built-in flash without a means to connect a sync cord for an external strobe. For these situations, the optional Ikelite DS Sensor #4100.5 may be compatible to trigger the DS125 strobe. The sensor detects the light output from the camera’s built-in flash and automatically signals the DS125 strobe to mimic the output. Some of the newest digital still cameras feature a preflash sequence too quick for the Ikelite DS Sensor to identify proper auto exposure, and the Ikelite EV-Controller #4100.6 would then be recommended instead.

The purpose of a strobe is to illuminate the subject and bring out the subject's true colors. Due to the loss of color when light passes through water, move in on your subject to photograph thru as little water as possible.

The maximum recommended lighting distance underwater with any brand strobe is

1.8m (6'). Selecting a subject at a greater distance underwater will provide mainly bluish color silhouette type images.

For more natural looking photos, add a second external strobe to control the highlights and shadows of your subject. For TTL automatic exposure, both Ikelite strobes should be connected via dual sync cord whenever possible. If maximum control for manual exposure is preferred, choose the optional Ikelite EV-Controller #4100.6, which provides 10-manual power settings in half-stop increments. The EV-Controller can be triggered using the built-in slave sensor or an optional sync cord can be connected.

The Ikelite SUBSTROBE should be given the same care and attention as your other photographic equipment. In addition to normal procedures, we strongly recommend that this strobe be returned to Ikelite periodically to be checked and pressure tested.

1. We suggest storage of your Substrobe with the locking lever OPEN to allow any

hydrogen/air mixture to escape.

2. Always rinse the exterior of the Substrobe with fresh water after use. The strobe can be cleaned by soaking it in a mild soapy solution. Use liquid soap; RINSE and DRY the strobe before storage.

3. The o-ring #0132.36 is located on the inside rim of the DS125 battery pack. Keep the o-ring and the sealing surfaces clean. It is not necessary to lubricate the o-ring. Never use spray lubricant because it may crack the plastic.

4. Keep the strobe bulkhead connector threads clean and lightly lubricated. Also keep the sync cord o-ring and threads clean and lightly lubricated.
