RE: Silencer Kit.
Depends on a lot of things.
How noisy is your bow?
The bow design makes a lot of difference.
How quiet do you want to make it?
The two quietest bows on the current market are the Bowtech Desert Stryker and the Horton reCon 175.
I've got a reCon, added two Bowjax limb silencers to it....all I get now is a fairly quiet "thud" sound. Very nice!
Then there are some bows...like grumpy says....not much you can do to make big steps to quiet them.
Though of the three silencers I've tried, the Boxjax come up a bit better than the others...to my ears anyway.
