So I played with the kids Diamond Edge SB-1 this afternoon shooting several different arrows through the chronograph at 45 and 55 pound draw at 24" , 25" and 26". Figured I post it here because I couldn't find anything like this when I was trying to get an idea which bow to buy for my son The draw weight is accurate according to a calibrated 100 pound scale 1/4 pound resolution , the arrow weights are +/- 4g The draw length is adjusted according to the draw adjustment module on the cams. If anyone is curious about a draw length , weight arrow weight combo let me know and we'll set it up and see. I had planned to make a you tube video with all this but the weather here was crap today . 45 Pound Draw weight 24" Draw Length 300g=231fps 400g=204fps 455g=195fps 25" Draw Length 300g=244fps 400g=216fps 455g=203fps 26" Draw Length 300g=256fps 400g=228fps 455g=215fps . 55 Pound Draw weight 24" Draw Length 300g=250fps 400g=218fps 455g=208fps 25" Draw Length 300g=261fps 400g=233fps 455g=221fps 26" Draw Length 300g=273fps 400g=245fps 455g=231fps
