I shoot a Dren LD set at 52-lbs with a 29.5″ draw. The only add-ons are a Shaeffer drop-away, Spott Hogg Hunter and a Dead End string stop. It’s a pretty smooth set-up but it seems a little loud to me. Not really lowd but there is a definite “thwack” when I release. Everything is tight and there is no vibration noise, it just seems alittle loud to me.
From a technical and tuning perspective, what can be done to quiet a bow? Are there mods that can be made?
JDGSometimes the Schaeffer rest can make a thwack at launch. They offer a damper module that screws into it that makes a world of difference. We put them on every one we sold when they were very popular in our shop. Contact john or Jason at Schaeffer and they will take care of you. Also, make sure Ata and rotation specs are good. If the string and cable are original,(or not), there may be some issues that way.black z7 magnum,tommy hogg,qad,b-stingers, vaportrail: blue smoke triumph,sword,hamskae,b-stingers:desert tactical chill R, tommy hogg,limbdriver pro v,ktech, black chill x pro, limb driver pro v,sword,B-Stinger.99,
Spoke with Jason. Very nice fellow, generous with his time and advice. I’ll replace the fuzzy sleeves on the prongs which are very worn and compressed. That’s about all I can do with the rest as far as quieting it down.
Question: does the weight/spinearrow effect on the level of noise upon release?
Joined: 5/30/2010i might be insane..but i think ALL bows seem loud when you are shooting it.
just recently, on a hunting trip, we made camp and i pulled out my bow to make sure nothing moved. i fired an arrow. typical sounds to me. definate TWACK!
my buddy standing about 8 feet away unloading his bow says, “dang, your bow is dead quiet!”..
have someone else stand nearby while you shoot, you may be surprised how quiet it is. being right there, inches from the bow..you’re bound to hear something.
just a thought.
if it is really loud to someone else..pull out the tape measure and make sure it is in spec. i find heavier arrows quieter than light ones.Yes, heavy arrows are quieter than light ones because they effectively absorb energy from the bow at release. The module I was referring to is a brass weight with rubber inside it that screws into the rest in place of one of the windage screws at the back of the prongs, it is about the size of a pencil eraser. I will try to get a pic of it for you.black z7 magnum,tommy hogg,qad,b-stingers, vaportrail: blue smoke triumph,sword,hamskae,b-stingers:desert tactical chill R, tommy hogg,limbdriver pro v,ktech, black chill x pro, limb driver pro v,sword,B-Stinger.I’ve noticed that the HS in the lower position quiets a long riser better than the HD. The HS didn’t do anything for my Drenalin, but may help the Dren LD. The HS comes in regular version and Lite version … if the bow is top heavy, rolls top limb forward post-shot, then the regular HS may help to balance it, otherwise the HS-Lite will help keep the weight down.
Make sure the string is barely touching the Dead End stop. Leaving a gap may increase the noise. KTech makes a KSB-1 for the Dead End Stop with a HS/HD in it.
With the bow in spec, and cam rotation correct, check that the string just touches the idler and cam suppressors. A gap here can increase noise.
Using a piece of thin rubber as a sound insulator between the sight mount and riser can cut down some of the sight vibrations reaching the riser. A sound insulator for the rest that 99fatboy suggests may also help.
Otherwise, this article covers some of the technical considerations and options to try, including a heavier arrow:
I don’t have a dampener on my Shaffer. Did it come with or is it an accessory?
JDGIt was an acc’y offered by Schaffer. I was surprised when you implied by Jason’s response to you, he seemed to have forgotten about it. It has been several years since it was introduced. Maybe give them another call, and I will see if we still have some at the shop. It was a nice addition.black z7 magnum,tommy hogg,qad,b-stingers, vaportrail: blue smoke triumph,sword,hamskae,b-stingers:desert tactical chill R, tommy hogg,limbdriver pro v,ktech, black chill x pro, limb driver pro v,sword,B-Stinger.
