Clay–This got me thinking:roll:. I thought I had posted this site http://WWW.cybertracker.org before but a search showed nothing therefore, you and BHA may want to check it out. Not only does it have awesome videos of persistence hunts and two great books for free download, Dr. Liebenberg has developed hardware and software that to my small brain would be a great asset to not only your profession but to all who can gather data in the field for scientific research. As I read the site it’s free to certain type organizations. Worth a look if you don’t know about it.
