The TX-4 is the result of testing to find a bow that perfectly balances speed and a smooth draw.With an IBO speed of 330 fps, this bow uses the smooth drawing Z-7 single cam to produce a draw cycle that NO OTHER speed bow I have tested can match.During testing of this bow in demo form, many customers commented on how my 72 TX-4 felt much like their hybrid cam 65 draw.(pictured with R282 cam)Specs: Right handed Axle to axle - 33.5 inches Brace Height - 6.25 inches Speed - 330 fpsCam:Z-7 Single Cam Draw Lengths - 29 inches Draw weights - 70 pounds Let-Off - 75 percent Weight - 4.1 pounds Realtree APG camo
