Not really interested in buying them a drink...have a couple of untouched spots where yotes are howling every night and wanted to pick up that call to try.
So on to your question. I have never used the call you mention. But I do use the primos calls. Your spots may be untouched,but are the areas around it untouched ?? I would start off with a young pup or female howl and see what happens.
Predator Sniper has recently reverted back to the original owner and is in limbo right now. There web-site is gone too. Their calls and shooting sticks are pretty rare, but there are some out there. Good luck!
I had checked with Midway and they were out (at the time I posted the question). If anyone stumbles across a place that has them, please let me know. By the way, I did start out with a hurt pup and had no takers. I did have one check out the Wiley howl but only came to 350 yards. If I would have went out in the moonlight I am sure there would have been more. I couldn't make it out that late and I never have much luck in the evening. Mornings seem to be better for me.
