Nautilite ReefMaster 1300 Zoom Underwater Torch

The Nautilite ReefMaster 1300 Zoom is a powerful and versatile underwater torch designed for divers who want maximum flexibility from a single light. Featuring a zoomable beam from a tight 8° spot to a wide 73° flood, this torch adapts easily from signalling and long-range viewing to wide reef illumination.

The ReefMaster 1300 Zoom is ideal for divers who want one torch that can do it all — from narrow-beam signalling and low-visibility penetration to wide-angle reef exploration — all in a rugged, travel-ready design.
