I think the first Game Crusher models were made specifically for Dicks sporting goods by Barnett and sold by them a few years back. I'm guessing that would be the 2.0 model.I did some research on the Barnett Game Crusher crossbows:
These crossbows come in two series: 2.0 and 3.0
Both crossbows have the same 165 pound draw weight, 11.38" power stroke, 21" axle to axle, bristle arrow retainer, 4 x 32 mm scope, 3 each 20" Head Hunter arrows (the ones with the Easton label), rope cocker and lube wax.
The 2.0 model as a zero creep 3.5 pound trigger pull where as the 3.0 has a zero creep 3 pound trigger pull.
The 3.0 has the trigger tech. I did not find any information on the 2.0 as it was built earlier so it may not have it ??
The 2.0 shoots 330 feet per second while the 3.0 shoots 340 feet per second. My thought here, being both crossbows have the same draw weight limbs, power stroke and same length string and cables, the 3.0 cams are advanced more to increase the speed. Advancing the cams on a well tuned crossbow and shooting the same arrow-point combination weight will increase the speed in feet per second.
Doing an internet search for cables and strings, I selected 60X for there high quality product and excellent customer service. The string measures 35.75" The cable measures 20.813" Both are constructed from BCY D97 material. String and cable set $84.95. String only $34.95
Checking many reviews from several websites, these recommendations were made:
1)up grade the string and cable system due to Barnett's poor quality. Some strings broke with as little as 10 shots while others quickly started to fray.
2)up grade to a better quality scope.
3)up grade to a better lubrication. My recommendation is the Trident Silicone Grease available on the internet in a 2 fluid ounce jar. This is a high quality product that does not dry out or gum up. A wee bit goes along way.
4)up grade the 20" arrows to either of:
a)Barnett Custom Head Hunter (no Easton label) 410 to 412 grain which includes a 100 grain point. These are very rigid and extremely accurate. Available in an 8 pack on Ebay
b)Carbon Express Pile Driver which weigh 450 grain including the 100 grain point. These arrows are rigid and extremely accurate. Available in a 6 pack on Ebay
Doing the up grades and proper tuning, one should have a good quality crossbow at a reasonable price.
All the best.
I dont know what Pile Driver arrows you have.The ones I had were not rigid at all even though they were heavy with light inserts. They had a very weak spine.Probably the flimsiest crossbow arrows I've ever seen with very little foc and were not accurate for me at all.
