Illuminate the underwater world in rich, natural color at depths up to 328' with the YS-D2 Underwater Strobe from Sea & Sea. It features a guide number of 104' / 32 m on land at ISO 100. This value changes to 65' with the supplied Diffuser 120 or 78' with the supplied Diffuser 100. The flash has a beam angle of 80 x 80°, which is widened to 100 x 100° when used with Diffuser-100 and 120 x 120° when used with Diffuser-120. A daylight-balanced color temperature of 5600K enables the strobe to restore colors absorbed underwater for more vibrant and accurate images.

Both TTL and manual flash exposure modes are available. Unlike the previous YS-D1, the YS-D2 features audible and ready-light TTL confirmation. The rear side of the strobe features a glowing panel with easy-to-read controls. The YS-D2 is configured with a 5-pin sync cord connector and a fiber-optic port for connection to an underwater camera housing. It is powered by 4 AA Alkaline or NiMH batteries.

Guide Number
  • 104' / 32 m on land at ISO 100
  • Changes to 65' with the supplied Diffuser 120 or 78' with the supplied Diffuser 100
Coverage
  • Beam angle of 80 x 80°
  • Widened to 100 x 100° when used with Diffuser-100 and 120 x 120° when used with Diffuser-120
  • Diffusers help create soft, even light to reduce glare, backscatter, and hard shadows
Color Temperature
  • Daylight-balanced color temperature of 5600K enables the strobe to restore colors absorbed underwater for more vibrant and accurate images
  • With diffuser in place, color temperature is reduced to 5250K, which is still close to daylight-balanced
Target Light
  • Included LED target light with red filter helps you avoid disturbing the skittish sea life that is likely to be alarmed by normal light. It is fitted inside the diffusers
  • Target light's output is adjustable in 2 steps: 100-300 lumens
  • Automatically turns off when strobe fires and turns back on after 0.5 sec
Depth Rating
  • Safe for use at depths up to 328'
  • Features over-pressure relief valve
Controls, Modes, and Operation
  • Both TTL (DS-TTL and slave TTL) and manual flash exposure modes are available
  • Sea & Sea's DS-TTL II system has been improved, with an added function that stabilizes light emission by controlling voltage differences--so variability of intensity will not be evident during continuous firing
  • Accuracy of TTL exposure has been increased, and images are less likely to be overexposed
  • EV control function can fine-tune amount of light emitted. Exposure compensation range has been improved to +/- 2.0 EV: -2.0, -1.5, -1.0, -0.7, -0.3, +0.3, +0.7, +1.0, +1.5, +2.0
  • Custom function allows for compatibility with cameras that have non-standard pre-flash in DS-TTL and manual modes
  • Illuminated control panel for good visibility in dark conditions
  • Color of illumination changes to indicate mode: aqua blue for DS-TTL, blue for slave TTL, orange for manual pre-flash, and green for manual mode without pre-flash
  • Large knobs and magnetic rotary switch enable improved handling and fast operation, while helping to prevent accidental activation/deactivation
Power Source
  • Recycle time is about 1.5 sec with NiMH batteries
  • Flash features audible charge signal
Connectivity
  • Configured with a 5-pin sync cord connector and a fiber-optic port for connection to an underwater camera housing using an optional cable
  • Fiber-Optic Cable II from Sea & Sea is required to use DS-TTL ll function
Mounting
  • YS and ball mounts included for attachment to lighting arms
