Underwater slate and strobe bundle.

Multi-page slate with wrist fastening to securely attach to your arm and take notes while underwater. 

Can be used when snorkelling or diving. Bright yellow fastening remains clearly visible at depth. Slate pages are also useful for white-balance if photographing below 10m.

Strobe light is included and also brand new in pack, however fresh batteries are recommended before first use as this has been lying in a drawer for a while and I'm not going to use it (bought two, used one and had this as a spare).
