Underwater Kinetics SL3 eLED L2 Dive Light
A flashlight isn’t required equipment for most diving, however it is nice to have. Even during the day, there are dark cracks and holes that can hide undersea life. A powerful LED, waterproof light illuminates a lot, and is definitely necessary for night diving. While you can easily rent one or do without, I like having my own. And it makes a great, extra-bright regular flashlight for using around the house, too!
