It is unfortunate that so many hunters have jumped on that bandwagon. They used to be a great "secret" weapon! All kidding aside the can style calls can indeed truly make the difference. However, with most hunters using them these days you are begining to see educated deer that are starting to act a little spooky and WILL circle downwind before responding. I remember the first time I ever used a can call. It arrived with the DeerHunting Ecyclopedia by Lenord Lee Rue III in 1994, it was the "can" as we know it but wrapped in camo (Treebark) tape and had a small lid. Anyway, the first hunt I ever used it I had an awesome tall tined magnum buck respond! The buck came charging in looking for the "doe" he knew was there. For several minutes he wandered back and forth within 25 yards and I was never able to get the shot off. From that point on I became a HUGE fan of this call. The only thing that made it frustrating was that everybody I showed my "secret" call to just laughed at the idea of using this "toy" on a deer? Just ONE year later I used this call to tag my first true "trophy" buck! It was mid December and the frigid sub zero temps had kept most hunters out of the woods for weeks. About an hour before dark I had a group of 6 antlerless deer enter the picked cornfield and begin to paw under the snow for their evening feed. With nothing to loose but legal shooting light I decided to call to them. I tipped the "can" a couple of times and thought.... "man, that sounds great in this quiet cold air"! I had no sooner put the can back in my pocket when I looked to my right and there was a dandy 150 class P&Y buck standing at 30 yards staring intently at the doe group! He commited to entering the field to join them and as he slightly quartered at 25 yards I made a perfect hit! Needless to say...... I've been a believer ever since! Mix it with the best sounding grunt call in the industry, the HS True Talker, and you have the best calling combo possible. Good luck this fall.
