The prices / value of a full power hunting bow (compound) seem shocking!! On the retail end, there are prices of 600 - 1200 dollars. These same models sell for 60%-75% less when a year or more out of date. Is the tech. of bow development really progressing that quickly? Is the hunting bow market flush with buyers wanting the latest bells and whistles? The only other consumer item I'm familiar with that has so much depreciation would be a computer, though computers are really advancing rapidly in speed / power / size. Bowhunters, Archery competitors, please educate me.
