Can some explain to me the process in fixed broad head tuning. Since my heavy vs light dilemma I thought I would try & set my switch back xt up for a fixed blade to shoot pigs with. So I got some montecs just to try. Well they don't fly good at all. At 20yrds field points dead on broad head 2" high 4" right, 30yrds 4" high 6" right. I've been shooting rage hypo's & rage Xtreme out of this bow & they both fly with my field points out to 60yrds. I don't understand what would be make them plane off high & right. I've spin tested them & they are straight. Just don't understand. In my mind if I move my sight or rest to compensate for the broad head it will move my field point poa.
From 30 yards shoot a field point. And a broadhead. Then move your rest slightly to bring the broadhead toward the field point. Then repeat. Only make one adjustment at a time. Example: field point hits dead center, broadhead is high and to the right of the field point. Move your rest down slightly. Make only a 1/16 of an inch adjustment. Shoot the broadhead again and repeat until you hit at the same elevation as the field tip then do the same for left/right until the broadheads hit the same spot that the field point hit. Afterward, switch back to field points and make any sight adjustments that may be needed.
The reason that they don't fly with your field points like the mechanicals do is because fixed heads will cause minor out-of-tune flaws to show up where field points and mechanicals are more streamlined and don't have the ability to steer the arrow like the fixed blades do. It should only take a few shots to make the adjustments needed. Sometimes making one adjustment will also fix another. (moving the rest to the left might also cause the arrow to hit lower as well)
Do yourself a favor (for future reference). Download the Easton Tuning Guide Here. The cliff notes? Shoot a series of FP-tipped arrows at a known yardage (I start at 20), then shoot a series of BH tipped arrows at the same spot (be careful at close yardages). Compare BH impact to the FP impact. Correct as shown below and continue working backward in yardage. As you work backwards you will find you may need to fine tune things more, but also realize that form issues are accentuated at longer yardage as well. If you get a poor result, try shooting one more time to verify it wasn't just a form/bad shot sequence before adjusting further.
BB4tw already explained it well but it still doesnt make sense try seaching "How to broadhead tune" on Youtube,lots of great videos there.
I shoot Montec G5 and they used to shoot 4''High and Left compared to my field points, this year I heard about ''French Tuning'' and tried it on my bow. The result? all of a sudden my G5's were hitting bull's eye exactly where my field points were hitting, NO compensation needed... Give it a shot, it's the simplest and best tuning I've tried... .
