The Strobe Cover D/Z is made of neoprene and designed to protect Inon D and Z series strobes during transportation and storage. Also, the cover can be used during diving and contributes 96 grams (0.2 lb) of positive buoyancy, although buoyancy will decrease as depth increases. The cover is designed with a cooling slit on the side so strobe maintains normal cooling characteristics. Compatible strobes: D-2000 D-2000S Z-240 D-2000W D-2000Wn D-180 D-180S Z-220F Z-220S Z-220 *Strobe is not included.
