ther can be no snycronization with the CPS. It only as eccentric that is responsable for compressing the limbs as on any other single cam. it also as only on module. Try changing just one module on a two cam. I have shot for several bow companies and i have to say the Dartons are the closest to setting it and forgetting it.

Nock travel can be an issue but with the programs available today for arrow selection it becomes relatively non issue.I set up My 2001 Ultratec on my Archers Advantage last week and it told me to shoot a Redline 600 at 44#.I had some here that I was going to give my nephew so I decided to try them.Went out set the bow up and with a fallaway rest the paper was perfect at 3 feet,so I stepped back to 10 feet and the paper was still perfect.I was amazed that just eyeballing the bow with a perfect arrow that it tuned perfect.It was set a little nock high but who cares.I shot my best indoor score last weekend with it.Went out today and I was absolutely on fire but I have changed over to a 3d setup now and at 54# and 395. mags I had a 3 arrow 2" group at 60 yards before it got dark.I did it 2 times in a row.Not bragging and this is not my usuall but today it was what I was doing.The bows are better than we are.I havn't noticed the program telling me to go stiffer and even in a lot of cases with Carbon Express it will tell me to go lighter than their charts.
So it is not really that big a deal to have a little nock travel but I do agree that the older 1 cams did have too much.
It may present more of a problem for the long draw short bow users but they already have some things to overcome.

Hands down Darton has the most innovative cure for one cam knock travel. By combining the best attributes from single cam bows(no synchronization problems and quiet operation)and twin cam bows(speed and level knock travel)they give you the best of both worlds.The "post feed" cam and large idler wheel that Pearson is using works really well controlling knock travel but its still not totally level. Black Frog is correct about conventional one cam tuning its as easy as running your nock 1/16 to 1/8" high or running a string loop seems to accomplish the same thing.

Thanks to bonecollector for addressing my question on thhis thread about the nock travel as advertised by Pearson. I'm just wondering how you came to that conclusion, what kind of equipment you used? And how far from "perfect" is it? I'm just trying to learn so, in advance- thanks for your time.

Was a Pearson dealer until I closed my shop last year. Had gone to the Pearson factory on a dealer hunt at the time this cam was being made. they had a prototype Accu-Max that we shot and showed us the computer graph plotting nock travel. As I recall it showed less than 1/16" through the entire draw cycle at all available draw lengths. That is such a minute amount that for tuning we were always able to run a standard nock height like a twin cam. If I had not seen the graph I would never have been able to tell.

bonecollector: Keep in mind that "computer graph plotting" can be misleading. We had one manufacturer swear to us that his product had "perfect" nock travel. We asked him how he plotted the results and then duplicated his procedure when we got back to the shop. After we finitely measured and plotted the results, his test methods agreed totally with our equipment; which was far from "perfect". In fact, it was pretty bad.
I'm not saying anyone's information is wrong. What I'm saying is consider the source.

Heh, heh, I know which one Len is talking about, we received some info from him on his findings when discussing this particular product, and then tried similar tests ourselves and came up with the same conclusions. The bottom line is that most manufacturers will tell you anything you want to hear in order to get you to purchase product. Very, very few nowadays will tell you the absolute truth,(altho there are still a couple) therefore you must rely more on independent non-biased testing, this will provide more reliable, definitive conclusions. I've thoroughly tested MANY solocams over the past several years, and can honestly say I have yet to find a "conventional" solo system that is perfect. Good shooting, Pinwheel 12

Forgot that we had conversed on that subject. You're right, PW12, it is that same manufacturer. You memory is still good but mine is failing in my old age. <img src=icon_smile_wink.gif border=0 align=middle>

Did anyone read the article recently published in Archery Focus? I beleive it was written by Larry Wise. In the article he explained how he set up a jig for holding a bow on top of a ping pong table. The bow being held perfectly perpendicular to the white lines showed that even 2-cam bows do not have level nock travel. Most 2-cam bows measured about the same but 1-cam bows varied greatly one from another. I posted on another board about the tips of my nocks wearing off the underside of my g-nocks when shot from a Mathews bow and no one seemed to know why. I think the author's desription of the downward nock travel and the resulting crash into the rest explained the problem very well.
