Ikelite Underwater Digital DS-51 Sub Strobe (includes ball mount) 4044.1

The compact, lightweight and affordable Ikelite DS51 Substrobe is an excellent choice for any underwater photographer. The DS51's intensity and angle of coverage are great for both macro and general photography. Ikelite strobes have the warmer color temperature output preferred by most photographers. The strobe's wide-angle diffuser increases the angle-of-coverage up to 80 degrees, softens the light and helps to reduce backscatter.

TTL and Manual Modes

The strobe can easily switch between TTL/Auto and any of the six (6) manual power settings for complete control over lighting the subject. The DS51 Substrobe's power rivals strobes twice its size, recycles in a quick 3.5 seconds, and provides 200+ flashes on a set of batteries.

When connected using a sync cord to Ikelite TTL housings, TTL adapters, the DS51 Substrobe offers TTL and Manual Modes. When used with other manufacturers housings, the DS51 Substrobe can only be used in the Manual Mode utilizing the six selectable power settings. When used in conjunction with the EV-Controller, the DS51 Mode switch is set to the TTL setting and the EV-Controller provides ten power settings in half-stop increments. A flash diffuser is included.

An included #9571.4 mount with 1" diameter ball allows you to build a custom arm or attach the strobe to standard arm systems.
