I recently finished graduate school and was in no position to have hounds of my own so I hunt with friends of mine. The guys I chase with 99% of the time do not use telemetry collars, they are old fashioned like that. I have chased from time to time with some other guys that use the collars. It's not always listen for them treeing, a lot of times you turn them loose and within minutes you won't hear them at all. You then have no choice but to get on the tracks and follow it out. I have treed lions 1/4 mile off the road or after following them for several miles over very serious terrain. We can kill them here there is a season and quota and you must buy a license. Generally each district has a quota for males and females and as long as the quota is open you can kill. From Sept to Dec it is open but no dogs are allowed. From Dec. 1 to April 14 it is legal to use hounds. Even after the quoata closes you can still chase and tree but no harvest is allowed. I live about 3 1/2 hours away from my friends with dogs but they are probably out looking for one today!
If you like that stuff I have a lot of pics and stories to go along!
