We're using it with decent enough results, but as SD said, it's not overly loud. It is a little louder than the old Johnny Stewart cassette tape (with amp) that we were using but nowhere near as loud as a FoxPro. Keep in mind there are only 2, maybe 3 decent crow calls on this machine and you can't load anymore into it.
It's not terrible but a good example of getting what you pay for.
A guy here at the plant bought one, instead of a Foxpro. He now wishes he bought a Foxpro. My old Jonny Stewart Cassette caller was louder then his Flextone.
I agree, don't waste your money on anything other than a Foxpro................their customer service is worth every extra dollar that you pay for their calls.......not to mention the superior product
