Do you crave subterranean adventures? So does the DUO S caving headlamp! Ultra-powerful, with 1100 lumens in BOOST mode, the this lamp runs on a rechargeable battery. Waterproof and durable, it’s ready to take on the moisture and mud of underground caves. When you’re in a group, you can count on the comfort provided by the FACE2FACE anti-glare function, which allows you to face each other without blinding one another. What will you explore today?
- Five lighting levels, plus BOOST, to adapt lighting to a variety of situations:
- Close-range lighting: low-intensity wide beam maximizes burn time
- Proximity lighting: mixed beam with brightness suited for comfortable proximity vision
- Lighting for movement: mixed beam includes focused lighting that allows for greater ease of movement
- Lighting for rapid movement: more powerful mixed beam allows users to anticipate the terrain
- Distance vision: highly focused beam for long-range vision
- BOOST mode provides temporary maximum power of 1100 lumens
- Highly durable:
- Waterproof in up to 1 meter of fresh water for 30 minutes and up to 3 meters for 10 minutes when passing through sumps while caving
- Excellent fall, impact, and crush resistance
- Rechargeable battery:
- 3200 mAh Lithium-Ion battery
- Recharges in 4 hours with quick 110/240 V wall charger (included)
