My present straight flight range record on a full sized hunting throwstick is 147.5 meters with a Central Desert Hunter. This throw was achieved on Oct. 2, 2017 at Centenial Park, and multiple throws were landing at this range, mainly at about 140 meters. At Boomerang Nationals 2017 in Columbia SC, Gary Broadbent was throwing some of our kylies 150 meters or more at the event. I was not present but was notified on the phone. I believe the potential for throws beyond these ranges is possible with continued research.

If people are interested in long ranges, small thin kylies can be made to achieve ranges in excess of these, where they are easily lost. These sticks are not practical for actual hunting.

Update 2023: Lowik64 on Instagram has thrown our Central Desert Hunter 172 meters verified by him on Google Earth. He's a pro knife thrower and has a very strong arm!
