What is it and how do you do it?

hit your arrow rest hard enough aginst a tree to make it move this will detune a bow quick[8D]

LOL @ BPS!

I think the term 'detuning' was dreamed up by the guys who erroneously think tuning the bow to shoot perfect bullet holes in paper makes for a perfectly tuned bow. Then they find out the bow won't shoot broadheads the way it should, so they have to make adjustments.

They are 'detuning' the bow from shooting those perfect bullet holes in order to make their broadheads shoot straight. To my mind, they are not detuning at all. The paper tune has given them a rough tune and they are fine tuning the bow to shoot broadheads.

I figured if i hang around long enough someonewill tell us what detuning means[8D]
Thanks Arthur

Well, ya know... On thinking about this, there is another way to go with this detuning stuff. Say you've got your bow tuned to shoot broadheads perfectly, but it won't shoot field points to the same point of aim.However, you really, really want your field points to hit right with your broadheads. That way you won't be forced to change your sight settings when switching from broadheads to field points.

So, you detune the bow from shooting your broadheads perfectly to make them shoot to the same point of impact you get with field points. It's not perfectly tuned for either, but maybe good enough to suit your needs.

That would be detuning for the sake of convenience.

I beleive its what you do to your bow when you sell it to your 3-d shooting partner who always gets you by a point or two!!!!

Arthur explained it the way I often use it. You will hear me use this term at times. Basically what I mean when I use it is that if you have paper tuned, bare shaft tuned and group tuned your bow, rest and arrows and they shoot as well as you can then it is tuned the best you are going to get it in my opinion. Now if you discover it will not group field points and your broad heads in the same exact spot and this is your ultimate goal then you will have to re-tune the bow to accomplish this. And in some cases you may actually be DE-tuning your bow to get these results. It would depend on how far off your spine was since this is what normally effects where your arrows impact.

Whether it is enough to make a difference to you depends on what your ultimate goal is with the bow and how well you shoot to begin with.

Arthur, I've always wondered about this one. It seems to go against logic. Is a bow truely tuned properly if you can't get broadheads hitting in a similar spot to field tips? It suggests to me that something is not right, otherwise the broadhead wouldn't be affected differently. Of course, when I consider bow tuning, I always include the arrows in this equation. Proper spine and high FOC helps when trying to resist the tendency of a broadhead to plane.

For example, I would never consider a set-up tuned that had broadheads impacting 4" away from field tips at 20 yards, yet I constantly see guys moving their sights and not worrying about what caused the broadhead to plane that much. That would leave me real uneasy about hunting with such a set-up.

Straightarrow, when you switch from field points to broadheads, you've changed the total length of the arrow, which moves the arrow's balance point. You've added to the arrow's frontal surface area. You've added wings to the front of the arrow which contend with the arrow's fletching for control of the arrow. Too many changes to assume one can tune a bow to perfectly shoot both at the same time.

For most people it won't matter. Either they don't shoot at distances wheretuning problems will eventually manifest themselves, or they don't shoot tight enough groups (at the short distances most people do most of their shooting)to really notice a half inch improvement in group sizes. Just because they can tune their bows to shoot both broadheads and field points to pretty much the same point of aim, within their skill level and average shootingdistance, doesn't mean the bow is actually perfectly tuned for both.That's simplyall mostpeople are looking for.

On the other hand,nobody can tune a bow better than their actual shooting skill allows (except in cases of blind luck).I suppose one could then make the argument that perfection is relative. What is 'perfectly tuned' for a backyard duffer would not be anywhere closefor a world class competitive shooter.

When I want to shoot broadheads, I forget about field points altogether. I tune the bow to shoot the smallest, most consistentgroups possible with broadheads. My field points probably won't strike the exact same point of aim, but why would I care? I'm looking for the best accuracy and consistency possible with broadheads.

Tuning to shoot broadheads and field points to the same point of aim is a compromise tune, done for the sake of convenience. It's not an indicator of a perfect tune.

So this is entirely a matter of perspective? If broadhead accuracy is yourinitial goal then a person is "de-tuning a bow" if they try to get field points and broadheads to hit the same point of aim. But, if yourinitial goal is to get fieldpoints and broadheads to hit the same point of aim then detuning could refer to adjusting your bow to get the best group size for broadheads.

Is that what you are saying?
