If your buddy paid 60 bocks he got ripped off. The one he has is the Big River goose flute. In my opinion it is the best flute call for the money. I've had Sean Mann's, Foiles Meatcutter, and a host of others. I've killed hundreds of geese with my big river. I've had it 20 years. Like any call it takes practice, practice, practice.
New birds make us all better hunters...eh.
