The fox boxes were built into ammo cans, with a small black rubber duck for an antenna. Inside they had a
piccon controller and generous lithium battery.
I hear Fox-2's camouflaging in the leaf litter was inspired by the recent hunt in Waterloo. Definitely adds
an element of challenge to the game. You can't just get in the area and spot it laying on the ground, and
have practically no hope of finding it without functional close-in sniffing gear.
