Sea & Sea YS-60TTL/N Strobe with Built-In TTL Sync Cord for Sea & Sea MotorMarine III, Nikonos V & most UW Camera Housings, Black.

The YS-60 has set the standard for size, cost and performance. A fixed sync cord adds to the simplicity of the flash by requiring only one user maintained cord connection.

Sea & Sea adopted a special prismatic diffuser in front of the flash tube to create even higher intensity light in a tight oval pattern. The YS-60's built-in Duo circuit responds to N-type (used in MMIII) and S-type TTL circuits, both used in Sea & Sea housings.

The YS-60/S is compatible with the MMII-EX camera system. The YS-60/N is compatible with MM III, most underwater camera housings & Nikonos V cameras.

A coverage angle of 105° x 95° covers the underwater picture areas of the 15mm and 20mm wide angle lenses. The guide number is 22 (land). It has a full and 1/2 power light level control.

Use of the accessory diffuser softens the light and helps reduce backscatter. The accessory diffuser reduces the light output by one f-stop, combined with the power control to give 4 stops of control.

1700mA Ni-MH batteries will provide 260 full power flashes with recycle time of 3 seconds. Much shorter recycle times will be experienced during TTL operation.
