While I don't personally own an Inferno; I do own a Shockwave and the original Xr-6. I have had issues with both callers; but the reason I will never buy anything but a Foxpro is there customer service. I had to send one caller in after 4 years of use when I started having issues. They completely rebuilt the caller without any questions and shipped back to me free of charge. Recently, my new shockwave was having some sound issues. They told me to ship it back and received it 10 days later. Turns out that the memory card was defective, causing the sounds to skip. Again, free of charge and no questions asked. I think any electronic product offered today can likely have issues down the road. A company that stands behind there product is very hard to find in today's world. The inferno comes with a 3 year warranty; which is good for a $200 caller. One thing that is a must with these callers is the Nimh batteries. The cold weather doesn't affect them. You will have issues with alkaline batteries in the cold; trust me. The other thing to consider is how far you need the sound to travel. The 4 battery units have there limits on volume, but will fine for most situations. When you step up the 8 and 10 battery units, your volume is much greater and enables you to call farther in the wind. This looks like a good unit for the price though. Good luck.
