The Mares Rover 10LR is a compact, rechargeable primary torch for everyday recreational diving in Indian waters. A single CREE LED puts out roughly 950 lumens in a focused beam, so it cuts through silty water and lights up reef crevices, overhangs and the shaded undersides of structure where the more interesting marine life tends to hide.

It runs on an in-house rechargeable battery that you top up with the supplied USB cable, so there are no loose batteries to track down before a dive trip. A visual LED charge indicator shows when the cell is full and how much charge is left, and at full power the burn time runs over two and a half hours.

Operation is simple. A multifunctional mechanical switch cycles through On, Low, SOS and Off, and an electronic lock stops the torch switching on by accident in your gear bag; a double-click wakes it up. With an adjustable wrist strap and a pocketable body, the Rover 10LR works as a compact primary light or a backup.
