What is the difference between a sub-strobe and a regular strobe? I had both full strobes, but one flooded my last trip. I do not have the funds for the full strobe, and was wondering if for wide angle photography if this would be sufficient for my photos when used with the DS161 strobe? Thank you. Carol Schoelch

Compact and Easy To Use
The size and weight of the DS51 make it the perfect choice for the traveling underwater photographer. The DS51's intensity and angle of coverage are comparable to any strobe in its class. The strobe can easily switch between TTL/Auto and any of the six manual power settings through a large, easy-to-turn dial on the rear of the strobe.
A simple battery door is easy to remove and replace and provides a clear view of the o-ring seal. The strobe's battery compartment is independently sealed from the electronics preventing further damage in the event of a flood.
TTL Flash Exposure
When combined with a compatible Ikelite TTL system or film TTL system, the DS51 automatically adjusts brightness to provide perfect exposure whether you're shooting macro, portrait or wide angle.
Sync Cord and Arm Kits
Convenient arm and sync cord combination kits for attachment of the DS51 to Ikelite TTL systems.

Convenient arm and fiber optic trigger combination kits for attachment of the DS51 to systems utilizing the camera's built-in flash.
