You can check Ed Sceery out from top to bottom, and you will find that he and his products are top notch. The quality and realism of his calls are just part of the quality equation involved here; his approach to the predator calling is right on too. I would say that Ed Sceery is one of the few people involved in the call making industry who is an animal scientist, and his advice is solid, just like his calls. Armor plated, silent on the lanyard or in the pocket, and by far the easiest to work on in the field that I have seen. Any of you newer hunters who have trouble out of the closed reed calls locking up in extreme cold weather, keep in mind that you can keep those calls out in the cold weather in a plastic bag, never exposing them to the heat of your vehicle or your house, and it cuts down a lot on the condensation forming within the calling chamber. Also, it is a good idea to bring the air through backwards by putting the business end of the call to your lips and drawing just the cold air through the mouth piece using an inhaling motion as opposed to blowing all that moisture from your breath through the mouthpiece.
If I could only take one call with me, it would be the AP-6 with an extra reed or two. Another good trick to remember is that you can take one of Sceery's larger barrel calls and insert the coaxer mouthpiece and reed, and make a longer range coaxer out of it. Finally, Ed Sceery is not hard to reach for customer service, extra reeds and the like.
