Hi there gang!
Have seen a thread on here about noisy Woodsmans but I cant find it.  

That's wierd.

I shot my avatar boar with them and they are whisper quiet out of my set up.

Sorry I'm not more help.

Good luck,

Todd

It's the hiss of Death, don't worry about it. BUT make absolutely sure that they spin true on your arrows. My WWs and Snuffers fly quietly.

I am not getting any noise out of my woodsman 125gr + 75gr steel adapters.How fast is your bow shooting I am around 160 to 175 FPS with by hunting bows.

Like C2 says, it's widely known as "The Hiss of Death" Some snuffers and WW just do it regardless of what you do. Yes, Make darn sure that they spin PERFECTLY true on your shafts. Then, just shoot.

Mine also hiss, I have them on 100 gr steel adapters.  I sharpened the back of all three thinking that might help, It did not not.

I had a friend a while back had this problem.He lined them up with his cock feather.They were lined up in between.Fixed his problem he said.

mine are quiet,i line them up with my feathers on wood arrows.i havn't had aby noise out of screw ons.snuffers have the hiss of death mentioned above..chris      

Thanks guys, I think I'll stick with the Magnus 2 blades for Africa then. I'll try aligning the head with the flech....

I believe if you round the edges of the vents in the broadhead it will make them more aerodynamic (improve air flow)and that should help quiet them down.

Yep, they probably arent mounted perfectly strait which will cause the whistle as air rushes over the inside edge of the blade cut-out at the rear. Everyone should make themselves a spin tester apparatus.  Very cheap and easy as far as do-it-yourself projects go. Pm me if you want advice...(it's so easy and cheap to do).  

Forgot to add they could whistle even though you have done everything right.  In that case using a small chainsaw file or fine sandpaper rolled around a toothpick for example you can knock that 90 degree corner (6 actually) off really fast.

As Randy just said, any hiss is usually caused by air hitting the back edge of the vents. If they are on true, air should not cause a hiss. Put a little vaeline on the back edge of the vents of those that hiss and see if there is a difference. One other reason is if your arrows are not spined quite right and air hits the vents due to less than perfect arrow flight.

Mine work great ! I love them on hogs or deer. The most important part in archery , THE ARROW!!CHECK YA AARAS

I had a set that used to whistle Dixie, kind of nice really.

how about the ones with the screw-in inserts that are factory installed,, mine wobble a little on the spin test and I'm curious if others do to?  think they would fly okay from 50#

Ted,
These are the factory installed 150's...     Arrows seem to be spined just fine, will check again though.

the arrow set up jason`s talking about is as follow`s/ 29" cx edge hunters 250`s  3x5" feathers & 150gn screw in`s being shot out of
a 52" 60# @28 checkmate raven .arrows are weighted with strimmer ( weed whacker ) cable
total weight of 640gns doing about 160fps .
28.5 draw

gene what set up do you use in africa ? the guy`s me & jason hunt with ( other members of the bba ) all shoot shoping trolly`s & are trying to talk us down in arrow weight saying heavy arrows from our bows wont be fast enough for impala & other similar size animals ( in 06 i had an ampala jump my 55# widow @ 15 yds from a treestand !!!) although i took a beautiful 50" kudu bull the day before we came home ,any advise would be great thanks

My setup is spined, paper tuned, fletch aligned, shooting bullet holes and my Woodsmans still hiss.  I think I will try Gene's suggestion after that I will be at a loss.  Is it really that big of a deal say 20 yards or less?
