The Nano is our most compact light. It's compact size and light weight makes it ideal for scuba divers and free divers who want to: 
- Mount it on a mask strap (mask attachment available as optional extra)
- Mount it on a cray loop (cray loop attachment available as optional extra)
- Store in a pocket as a backup

There's two versions of the Nano, the Nano 600 which is white light version and the Nano Red which is a red light version. 

The white light version is great as a backup light or as a low output white light.  The red version is great for not disturbing the marine life and not effecting your night vision, so it's great for hunting crayfish or not effecting your night vision for looking at things close up on a night dive. 

The light comes with a 14500 rechargeable lithium-ion battery that is recharged through a USB-C port in the battery. So you can use any USB-C cable to charge it.  It can also be run on a AA battery in which case the output drops to about 1/3 of the output on the lithium battery. This can be quite useful if you want less light.
