Bandit, Can you borrow any equipment from the Malaysian army? Most of the available units in the US are of Russian manufacture. These are the so called "second generation" units, and are vulnurable to damage from independent light sources. They are very rugged, following the tradition of Soviet gear. US starlight scopes are better optically, but extremely expensive. What are the typical ranges in the jungle you first locate elephants at? Do you locate by tracking, visual sightings or audio? Your elephants are facing the same dilemna as the African elephants- people. Perhaps we could sedate the plantation owners and relocate them ;O)
