Mares Eos 5RZ is a powerful torch with a rechargeable battery and adjustable beam angle. With an adjustable beam angle you can change the torch from a spotlight to a wide angle floodlight perfect for normal diving or if you want to use it for filming. The rechargeable battery and adjustable power setting and beam angle make this one torch that has a range of uses.
One Torch, Multiple Functions
Twist the head of the torch in the water and you can adjust the beam angle from a tight 12° spot light to focus all its power into a small area. Turn it the other way and the light will spread out into a wide 75° smooth beam which is great for pictures, video and illuminating a scene.
The switch cycles through High / Low / SOS Strobe with a max power output of 503 Lumens. Inside you have a removable and rechargeable Li-Ion battery that you can charge from inside the torch by a USB cable.
