Tiny but powerful, the Tovatec Dash 2.0 Dive Light uses proprietary technology for a bright beam, tightly focused at 9° for illuminating objects at distance. The Dash 2.0 is depth-rated for 328' and runs on one included rechargeable 14500 lithium-ion battery, with up to 90 minutes of runtime on full power and three hours at the half-power setting. The light is controlled by a tailcap push button that's easy to operate even when wearing gloves. It's a great little flashlight for dryland use, too.
