I have had An old Johnny Stewart tape caller, a Fox Pro XR6 a Power dog and now the Alpha Dog.
The J. Stewart worked very well for a wired caller. The Fox Pro I had was a piece of crap as far as the quality and loudness of the sounds and the remote was a piece of ****. NOw the OLD POWER DOG as far as the quality of sounds was better than the Fox Pro and almost as loud. I was quite loud for a 4 battery caller and for its size. Plus the remote was real easy to use, didn't have much range but then again it was not claimed to be a LONG range remote.
Now this Alpha Dog is the cats meow so far. Very loud with great clarity of sounds, Plenty of preloaded sounds to do me. real easy to use remote and great distance.
It is really not fair to compare a 4 battery caller to an 8 battery caller for loudness as it takes more power / more batteries to have the real loud sounds.
For you that still might have an old Primos Power Dawg caller and are or have had trouble with some batteries not working or you got it and put batteries in it and it did not work so you sent it back and they returned it and it still didn't work with the same batteries as you first tried. Well what it is is that all batteries are not made exactly the same. I found this out because I ordered a couple extra battery holders for my Power Dawg, well for some reason they did not work with the cheap batteries I was trying to use. I would inset the batteries in the holders and test with a volt meter ,,they no worky
...
What I finally figured out is the Positive end (the tit that stick out)of all double AA batteries are not the same length.
I bought some quality batteries and to my surprise they worked. So as a have to know why guy I checked the length of the tit on the positive end of both brands of batteries with a set of Digital Calipers, the cheap brand the tit was quite a bit shorter than the quality brand battery.
Just a heads up if you had this problem.
