Title: 3 Under Bow Noise
Post by: Dan Landis on March 30, 2017, 04:35:00 PM
Recently tried shooting 3 under from split finger. Had to change my nocking point some to get good arrow flight, but the bows are very loud now.  Is there anything that can be done to overcome this?

String silencers, heavier arrow, maybe a different string material, adjusting the tiller if you have an ILF bow.  Regardless, three under just creates more noise because it flexes the limbs more unequally than split finger does.That means they vibrate more and make more noise as they come to rest at the end of the shot.

Haha shoot what you do best with accuracy wise, tiller is important with the three under style. The noise is greatly reduced when an even tiller is in the picture.
I would try three under and if your accuracy improves and you stick with it order a bow that has the proper tiller or have yours re-tillered.
I have also installed multiple string silencers which helps a lot.

I have my bow tillered at negative 3/16" for shooting 2 under and it's quiet as can be.

Everyone is confirming what I feared would be the answer.  Was hoping there was a quick fix, or something I missed, should have known better.  So far 3 under seems more accurate for me at 15 yards and under, still up in the air beyond that.

Years ago I was trying to learn 3 under using my Bear TD. I did the nock point adjustment, added Beaver Balls,dumped the D-97 string and was able to quite the bow down. The biggest difference came switching strings. Wish I could remember what FF string material it was. since then no D-97 on my recurves.

Dan if this is a bow you made, adjust the tiller for a negative 1/8th" at least.

Yeah as benbow says. It will never be as quiet as shot with split until you retiller it.

Roy, I plan to build a bow for myself real soon and plan to tiller for 3 under.  The bow I am currently using is the glass 64" d/r that I got in the trade several years ago from Ralph Morris.  I wouldn't want to start carving on that one.  I'll shoot you a PM when I'm ready to start tillering the new one, for a few pointers.

M60, I do have a D97 string on it now.  I'll try the old B50 string on it and see if that helps.

Thanks everyone for the help!!!

Try a brace height that is higher by about 1/4 inch.

Don't be afraid to raise the nock point.
The bottom on my top nock set is 3/4" above square.
That leads to another question....
Are you using two nock sets?  I not, upward pressure from the finger against the bottom of the arrow will change your tune and flight.

Wasn't there a post recently about using tubing on a limb tip and the resultant weight changed the tiller (limb response) enough to help quiet the bow ?  Search.  I can't remember who, but I believe it was one of our Aussie brothers that posted it.

Give that a try

I shoot three under and I would highly recommend two nock sets.

Build up the shelf or install and elevated rest.

I find that finger pressure makes a huge difference. Load at least 90% of the weight on your index and middle fingers with the ring finger just along for the ride. A heavy ring finger will really make the bow loud. I don't think it affects noise, but two nock sets are always a good idea.

I find this to be true as well. A heavy ring finger will always make for a noisy bow. But there is always other things that come into factor as well, brace height and what type of arrow, wood, carbon or aluminum, will also be key players in how much noise a bow makes.

I've been shooting 2 under and it really helped with noise and accuracy. Takes some getting used to as far as strength goes but I only drug my ring finger on the string anyway
