The Black Diamond Onsight 375 is a climbing specific headtorch with variable beam modes and a low-profile front unit. Black Diamond have prioritised simplicity and durability with the design of the Onsight 375. The light is operated with a single button and thanks to its IP 67 rating will continue to operate up to 1 meter under water for 30 minutes, so that unexpected shower isn't going to affect it. The battery housing is separate from the light and mounted at the rear. This helps balance the headtorch and means that the front unit is very slim, alowing you t oget very close to the rock without bashing your light.
The Onsight 375 will run on either Black Diamonds rechargeable Lithium Ion 1800 battery (sold separately) or 3 regular AAA batteries. allowing you ensure you always have a back up plan. Switching between wide beam Climbing mode and the 375 lumen bright, narrow beam Route-Finder mode is easily done by tapping the right or left side of the front housing.
The Onsight has a 6 level power meter allowing you to preserve battery life when you're out for longer periods. To save battery life and guard against accidental activation in storage there is a digital lockout feature. There is also a brightness memory so the light will turn on and off at the last used brightness level.

Customer Reviews of Black Diamond Onsight
This light may perform well, but I am seriously disappointed to find that it uses AAA cells. Almost all AAA cells, whether alkaline or rechargeable, cost the same as AA cells but offer 1/3 the capacity. AA rechargeables will give three times the duration on a charge.
