I have one and I haven't been able to figure out how to make it short enough to work on my Darton Impact which is 28" axle to axle and 29.5" tip to tip. If I could figure it out, I'm sure it would work just fine. Mine is several years old and will work on my Hoyt Viper compound which is 34" axle to axle. Maybe the newer ones will adjust to a shorter length to work on some of these parallel limb bows that are less than 30" axle t axle.
