I agree with 87predator. The Fusion is hands down the best electronic for under $500. Foxpro has great sounds and as geo4061 said, the TX-1000 remote is the bomb. No Off Season (Predator and Varmint Hunting Gear Specialist | No Off Season - Guided Hunts) has the Fusion in stock and we offer free shipping on any orders over $500. You can add an e-caller sling and pay for part of it with the free ship. You'll love this caller.
The Inferno will be out July or thereafter. Another couple to consider are the Foxpro Hellfire and the Primos Alpha Dogg. The Hellfire will have much more volume than the Inferno. The Primos is a good design with a nice remote but will not have the quality/service of Foxpro. Here are soome links:
Predator Masters has a Shockwave with TX-1000 remote for $450. He bought it a few months ago and only used it four four times. This is as good as it gets and at a great price. Time to pull the trigger.
This post is a couple months old but if you haven't bought one yet I thought I'd weigh in. I've been using a FoxPro spitfire (now discontinued but very similar to the wildfire)) for years. It has been a great call and worked very well for me. The only thing I don't like about it is that for the remote to work at more that 20 yards you have to have line of sight with the call uninterrupted by brush.
I don't think you'll ever regret going with any of the FoxPro calls. Just research the features you have to have and pull the trigger. The Spitfire I've been using was the least expensive model they sold ($160 at the time) with only the basic features and it's still great.
I think I'll be upgrading at some point to pick up a few more sounds and the whole FOXBANG thing sounds slick. Good luck with it.
Here's a couple summer dogs from last month. They were causing problems for the landowner's pets.
primos new dog catcher save your money for gas and ammo, $58.00 shipped. don't spend more than $100 for any caller. you only need about 5 sounds and never place your caller more than 20 yards in front of you. ya don't need a remote that works 500 yards ???? (what's that all about) . most of the new tech callers have problems seeing the screen in day light all callers will freeze up sooner or later from cold temps, I had the old primos power dogg for 6 years killed a couple truck loads full of coyotes with it the antenna finally broke and they had no parts or I would still have it.
