    Default at wits end

    Hey all, new member here,,, HI! Got a perplexing problem and my brain is fried. I've been shooting bows for 51 years now, and have never experienced a problem like this. I just received a new 2012 Silencer with Nitro cams for my birthday. 25-30 inch draw, with d.l. set in 27.5 hole. 55 - 70 lbs, set on 61 pounds. I am shooting Easton aftermath arrows,,,400,,,27.5 inches long with blazer vanes and 100 grain points. QAD rest completes the launching equipment. My problem is nock high tear. No matter what i do the nock still tears high. The cams seem to be in time. I have raised and lowered the d loop and the tear stays the same. I tried adjusting the draw weight, and different weight points but no help. My gut tells me its in the cams but they appear right on. I have shot martins now since 83 and this is the first problem i have ever experienced with them. Any suggestions wouild surely be appreciated..thanks

    I can't be 100% sure,

    but I believe my top cam is just a hair ahead(timing-wise) of the bottom.....or the other way around.....I can't remember...but I believe they are not perfectly synced

    sorry
    Hope this helps

    Move your nock point down or your rest up. If that doesn't help, twist the cables so it looks like the cams are "wrapping up" if the nitro cams are like the Cat Cams, it will help with speed and timing

    It sounds like the problem is definitely in your rest, either up too long, not long enough, or bouncing back and hitting. Do not advance your cam timing on those cams. I have had several models and worked on hundreds with the nitro 2.0 cams. set your timing perfect even top and bottom and set your nock height dead level thru the berger. Make sure your qad rest is level and properly installed, also if its not the hdx model throw it out, junk. I get bareshafts and fletched almost robin hooding at 20yrds, setting even timing and level nock, hope this helps. One more thing, get rid of the stock cable slide, not much vane clearance, I replaced all mine with saunders hyperglide.

    Welcome aboard oldman!
    TEN RING is right on! I have had that problem and had white vanes so the marks showed up the the vanes. Which was fortunately for me and no matter where I put the d loop it shot the same tear. You might want to us some spray foot powder on the rest and see about vane clearance

    I'd also think the problem is one of rest clearance. You could spray the vanes with foot powder or use some lipstick on the vanes to find out. Doesn't sound like there's an issue with arrow spine, but you could try a stiffer shaft (340) and see. If all else fails then change the rest. Maybe even an old prong rest, star hunter or something like that just for comparison. As long as you've been shooting you have to have a drawer full of old rests.

    Hey guys, thanks for all the help. Yes, it is an older rest. Its a Ultra Rest Hunter, circa 2009. It was my wifes', she updated, and I got the hand-me-down. No complaints tho. Guess its time to update also and see what happens. Any suggestions for a new rest? One thing I will say about the Silencer, even with the high tear, I am still able to keep a 2.5 to 3 inch group at 20 yds. Cant wait to see what happens when I can get everything in tune. Again, thanks for all the help
