First let me say that I have been bowhunting deer for 35 years, and I have used just about every top rated grunt call ever made. This year I bought 2 call's. I bought the QB Brawler and the new MAD Growler. First, the MAD Growler. It's a good call, fairly loud and works when wet. It has a more realistic sound than most calls and it can be used for small and big buck grunts. Second, the QB Brawler. I bought this one for my wife after I bought the MAD call. I wish I had bought myself one of these. This is the most realistis sounding grunt call that I have ever heard. It sounds exactly like a deer. It has a low deep gutteral grunt tone, but if you collapse the flexible piece you can make small buck grunts, and if you use it backwards, (inhale on the opposite end) it sounds like a doe. You can make the most realistic sounding grunts with this call with a little practice, and it's loud enough to be heard at a good distance. I doubt I'll ever use anything other than this call. It is by far the most realistic sounding grunt on the market today, and it works when wet too. It's about time someone got it right and made a realistic sounding grunt call! Buy this call, you will definately not be disappointed.
If you're going for big bucks, this is the call to use. I called in 2 bruisers with this call in the past 2 years and this last one was a perfect 10 point that weighed 205 dressed. Rack scored 165 B&C green. Very deep grunting sound that can be toned down for smaller bucks. Works even when wet and in the very cold. Never fails. I highly recomend this call as I've been hunting here in Canada for a while now and as I said before, it works even in the very cold and in extreme wet conditions.
