Which model should you choose?
For orienteering purposes all LEDX headlamps would suit. Your orienteering speed makes the differents. For those who just started with orienteering in the night, a LEDX Kaa will do fine. Kaa is also simple and comfortable to use, with its smaller battery, you have both the lamp and the battery on the head.
For the more advanced orienteerers, Mamba or Cobra is the ones to choose from. Mamba is very light weight yet gives you a very powerful light. Cobra is the top model with outstanding light performance and the obvious choice for the elite orienteerers, or if your vision is no longer on top. Used by the best teams and night orienteerers on the big relays and Championships.
