ULTRAMAX ULTRAPOWER UXDS-3 Digital Underwater Strobe Head with Diffuser

The ULTRAPOWER UXDS-3 Digital Underwater Strobe Head from ULTRAMAX is a flash with a depth rating of 197'. It offers a guide number of 66' at ISO 100 on land, as well as a power rating of approximately 25 watt-sec. It also has a coverage angle of 90° and a daylight-balanced color temperature of 5700K. There are 5 pre-flash settings to synchronize with the built-in flash of most digital compact cameras. Choose from power/brightness output levels from 20-100%. The strobe offers manual exposure control and has slave functionality, allowing it to be triggered by the firing of another flash.

LEDs indicate power level, low battery, and whether or not the flash is ready. The UXDS-3 runs on 4 AA alkaline or NiMH batteries, which are available separately and are housed in a compartment that's completely isolated from the electronics in order to prevent water damage to the strobe if the compartment is accidentally opened or batteries are changed when the unit is still wet from a dive. Additionally, the strobe has a durable housing made of corrosion-resistant polycarbonate. The supplied diffuser widens the UXDS-3's angle of coverage to 100° and softens its light to prevent backscatter, glare, and hard shadows. The strobe head is equipped with a standard YS connector for mounting onto an optional lighting arm.
