    Light Caution: The DS51 bulkhead connector is not waterproof and must be capped when not connected to a cord or sensor. Using a DS51 underwater with the bulkhead connector uncapped or unconnected will cause the strobe to flood. Do not continue to use a flooded strobe: return to Ikelite for repair.
  • Page 4: Introduction

    The Ikelite DS51 strobe is equally suited for general and wide-angle photography, covering up to 80° with a diffuser. The compact size of the DS51 makes it ideal for macro photography while its 5700°K color temperature helps bring out the true colors of the underwater world.

    STR OBE CON N EC TI ON The female Ikelite bulkhead connector permits Ikelite sync cords to be connected to the strobe. The sync cord relays a signal from the camera to the strobe that tells the DS51 when to flash.
  • Page 7: Ttl/Sync Cords

    Ikelite Sync Cord TTL SYNC CORDS Ikelite offers interchangeable sync cords so that the DS51 strobe can be connected to different camera systems. A TTL sync cord (illustrated above) is required to send the TTL/auto exposure signal from the camera to the strobe.
