Bring back stunning views from the deep with this waterproof Speedlight flash for every Nikon 1 underwater solution. Take it on the deepest dives, all the way down to 328 feet, and illuminate scenes too dark to capture without a flash. Select from four different flash modes, then use the Targeting Lamp to see where the flash will be directed and aid your Nikon 1's autofocus system. The SB-N10 Underwater Speedlight easily mounts on the WP-N1, WP-N2 and WP-N3 Waterproof Housings or Nikon 1 AW1 with the optional SK-N10A Underwater Bracket and SC-N10A Underwater Fiber-Optic Cable (SR-N10A Underwater Fiber-Optic Cable Adapter for use with the AW1) and has a guide number of 28/92 (m/ft, ISO 100).
