T.R.U. Bowstring Accelerator Balls Silence your bowstring while gaining up to 12 feet per second in arrow speed with these machined aircraft aluminum balls. Simply move the ball up and down your bowstring to quickly and easily adjust your arrow speed

I would not think, so I have now experince so maybe.

RE: do you thinks these work
 

I dont see how putting anything on your bowstring would make it faster.Am I wrong?

RE: do you thinks these work
 

Yes. :D

Sometimes placing things at certain points along your bow's string will in fact increase your speed by several fps. The trick is finding where those points along your string are located.

RE: do you thinks these work
 

Several companies already have such devices installed on the string. If on one of your cables, down next to the cam you have what looks like a piece of shrink tubing, chances are there is a brass nock or two in there for just that, gaining speed.

I took my factory installed string silencers off of my Vectrix and LOST 7 fps....I quick fast re-installed them.

Thanks Dan, I really had no clue about that. Shows how smart I am. :D I've never heard of anything like this TRU product. Guess you learn something new everyday.

RE: do you thinks these work
 

They absolutely do not work. They were first generation "vibration reduction" so to speak. Been outabout sevenor eightyears. I ordered them out of a Cabelas archery catalog.We crono'd my old High Country Four Runner way back when they came out. It was always slower no matter where we put them. They claim there is a sweet spot, but I wore out the those little screws looking for it.Irhuntr is right, nothing put on makes a string faster.

RE: do you thinks these work
 

Maybe they work...but with today's top of the line bow's, what is to gain by increaseing your spped from say 308fps to 312? So many are obsessed with speed, but 308 is very fast in itself.

RE: do you thinks these work
 

It's all about the location. As noted by somebody else, there are "sweet spots" on the string that will add speed. Rubber Eliminator Buttons will do the same thing.

12 feet is a pretty hefty claim, though. I'd say that's a little bit of a stretch.

RE: do you thinks these work
 

Mobow, I've always wondered what that thing was. I got one on my Reflex and it hadalways bugged wondering what it was. Now I know, thanks.

RE: do you thinks these work
 

Some days you learn two things. ;):D

RE: do you thinks these work
 

Yes, Reflex is one that does that. It actually works, though it goes against logic. All I can figure is that the extra weight, placed strategically, helps "pull" the cam over, propelling the string faster. Oh, and you're welcome.

Some days I feel like the dumbest guy on Earth too.

RE: do you thinks these work
 

You may FEEL like the dumbest guy on earth.........but you aren't, that spot is already taken. He's wearing.....nevermind, not going there. :D

If you can count to three hundred you're a step ahead of me. [:@]

RE: do you thinks these work
 

Well, let me see. 1...2...3...4......... give me an hour then we'll find out.

RE: do you thinks these work
 

I wasn't gonna go there...but since YOU did.....:D:D

RE: do you thinks these work
 

I knew what you were getting at. [>:]

;)

RE: do you thinks these work
 

I've hot rodded 12 fps out of my old HCA bows with the use of eliminator buttons and prestressing the limbs.

RE: do you thinks these work
 

I have not seen the string balls, but have seen the brass knocks with the shrink tube a few times but did not know what they were for. I learned something today;)

RE: do you thinks these work
 

i knew someone here had success with them...

didnt you have to use several of them greg?? i remember someone here saying it was a PIA and they had to use something like 11 or 12 of them placed JUST right but they did work...

the thing i never got was why do you loose so much speed with stuff on the middle of the string..likc nock, loop, peep etc..but gain, or not loose so harshly from things toward the cams.

mo...does that mean im going to LOOSE speed with my reflex when i have a new string made and put on??? that would be terrible..i am going to ask for my old string and disect it...i dont believe you:D lol..i always heard id more than likely gain speed with a new string since they are made better and more twists or strands or somethin i dont know lol

RE: do you thinks these work
 

Possibly.....Those were designed for those strings......A good set of new strings may be faster anyway. To be honest, I can't predict what will happen......But I assure you that's what they are, and they do work. Before you get your new string, chrono the bow, take those off, and chrono again. It'll be 3-5 fps slower.

Like I said, I took off my factory installed string silencers and LOST 7 fps.

RE: do you thinks these work
 

Do they work? Sometimes.

they reduce the vibration/oscillation of the string, so how much they work really depends on the bow and arrow combination and setup. 12 fps is a huge jump, I've more likely been in the 3-5 fps range.

They do however quiet the string down, again depending on the bow. I use to shoot a PSE Mach-8 that was noticeably quieter with them on. I now have a Hoyt ultra-tec and isn't nearly as noticable.
