View Full Version : changing cams on my sceptor4

07-03-2010, 09:46 AM
I have a 2008 sceptor4 with 14" Mag limbs and M Pro Cams. I'd like to try Furious X cams to see if I can get a little more speed out of it and see how I like the shoot thru system. 1st, where can I get cams? 2nd, does anyone out there no what the string and cable specs would be for this set-up?

Martin website says 50-1/2" shooting string and 39-1/4" cables. Go back to the martin website and click on specs and then click on 2010 specs and you have it. All martin Scepters, no matter what year, II, III, or IV use the same string and cable specs depending on the limb lenght.

You can buy new cams from a Martin Dealer or used cams on Archery Talk.
