I bought a "top of the line" PSE MACH-4", PETE SHEPLEY'S FINEST!! The one Pete Shepley used..., "The most advanced....blah,blah, blah...80 #, full cam magnesium handled bow back in '91 or '92. I shot this bow for a few years killing several deer (see base camp photos) and always shooting heavy arrows and giving it the ultimate in care, I had the displeasure of having it snap (explode) IN HALF! right under the handle, this past September, only 2 weeks before opener!. No, the limbs were fine, again...never stressed. I showed it to a Doctor (PHD in metallurgy) friend at the University of Michigan who I work with and he was quick to point out the bubbles that formed in the process of manufacturing this bow. It snapped along that line.
SO, I shipped it back to PSE (overnight FedX) and they sent me a brand new bow!! Wow, BUT WAIT , it wasn't a another top of the line SYNERGY LINE...no it was a low life GAME SPORT FIRE FLIGHT. PSE claims that it has the same power, blah, blah, blah, ya'da, ya'da ya'da..
So I exchanged my $400.00 top of the line bow for a $200 low life......Know what your REALLY getting on your warranty when you buy a bow...
So now its time to buy a Mathews or a Hoyt
