  • GTO Draw Force Curve

    Hello,
    This is a plot from a GTO. Its a 28" DL x 60#

    Oldbuck,
    I see 67% let off. Is that deliberate? Set that way?

      This was as recieved from Elite. Also it was on the pull / draw. All bows show max let-off when you come back off the wall slightly, then you get max let-off percentage.
      I'm sure I could improved the letoff, just wanted to see what the curve looked like. This bow also had an almost dead level nock travel.
      All in all a very impressive job by Elite.

        I don't understand.

        You would think if this is how it came from elite it should be allot closer to 80%

          Wow by looking at this and comparing my 07 Synergy as well as other bows I have owned the GTO seems to be one SUPER SMOOTH rollover.....
          Makes me really wanna get my hands on one to try.

            I understand when you pull harder into the stop the letoff geos up , but this curve should have showed 80% at some point.

              I got these results from my E-500.
              My let off-
              on the way up min. weight= 71.82% L/O
              on the way down min. weight= 77.67% L/O
              Some people try to turn back their odometers. Not
              me, I want people to know "why" I look this way. I've
              traveled a long way and some of the roads weren't paved.

                Why not 80% letoff

                OK guys, I'm sure I could have gotten near or at 80% letoff.
                I did not adjust the stop on the cam, I just wanted to see the curve. I was not interested at that point, about the letoff.
                So don't think the bow does not produce 80%. You can adjust any of these bows to have more or less let-off.
                thanks

                    The fact the valley never flattened but immediately went back up indicates the draw stop wasn't set correctly.

                      Hello Dave,
                      I did not define the valley, that would have taken readings at small (1/8") increments. My interest was the curve as it compares to other bows. The valley can be defined, I just did not take the time.
                      And yes, as I said, the stop could have been adjusted.
                      But what it DOES show, is an energy packed curve, it is a GTO after all.
                      Thanks

                        so were did you hit peak weight it looks like 20" is that right i have heard it should hot between 6 to 6.5"

                          If you add brace 7" + 1.75" + 6"- 6.5" draw cycle, peak weight should start at 14.75" to 15.25". This curve seems pretty close to that. It does have a slight bump near the center @ 20" which according to this video should not be above the first peak at 15"+ but it seems to me it would give a very nice draw. Was this curve plotted using a scale or a load cell which Kevin said is the most accurate way to measure and would that make a difference? I don't know.

                            Hello,
                            I use a load cell. Anyone can buy one, all the digital scales use a load cell for measurement of load which then displys on a screen for viewing. A spring scale is less accurate only in the respect that it is much harder to visually determine small changes in load, the display on a digital scale solves that problem. If all you have is a good spring scale and you are carefull, you will be able to make a pretty accurrate DFC.

                              Oldbuck Do you have the stored energy on the GTO at 60 lbs 30 inch DL? curious as compared to the 70 lb. that I have.
                              No ifs and or buts Just maybee.
