The Discovery Channel has been airing a 2 hour show about Borneo. Scientists and explorers joined forces to catalog animal species. Well I don't know if Petzl donated lights to this cause or if they are all just personal choice, but every person that I saw was wearing a Petzl product.
Myo XP, Tikka XP, and the Duo are the 3 that I can remember. That is pretty good for those "water resistant" products. I mean the Borneo rain forest air has to be like a full water dunk with equipment. I still like my Petzl products.
When in the jungle it is probably better to have DD long moon mode lights instead of flat regulation and , darkness.
