The electronic devices that are commonplace today simply didn't exist when I was starting to hunt. Now we can tell how many deer walk down a trail and even take pictures of them with a camera attached to a tree. Patterning is now the all-important strategy. When we kill a deer or elk, we can call our pals on a two-way radio and ask for help to get it out of the woods. Where we have cell phone service, we can call our wives, bosses or kids from the tree stand, and if we have a satellite phone we can make a call from the middle of the tundra above the Arctic Circle or from a Yucatan jungle. My biggest concern with any electronic equipment is ethics and fair chase. Hunters who use two-way radios to guide each other to game, for example, should be banished from the woods. Those who carry the new heat-seeking units designed to help find wounded deer should also hit the road if they attempt to use the devices to locate healthy, hidden animals.
