Sea&Sea YS-30 DUO-Strobes & Flashes
 (#10500)
It represented a radical new development in flash technology. Introduced in 1997, it was (and still is) the world's smallest (it fits neatly into the palm of your hand), lightest (less than a pound), submersible strobe that syncs for TTL flash photography in slave mode without a sync cord!
- Incorporates the unique electronic Duo circuitry to automatically adapt for TTL flash photography with both four and five-pin sync connectors
- 55º x 80º beam
- TTL slave capabilities are ideal for multiple strobe applications
- Super small flash head is ideal for single strobe macro photography
