Prime Inline 3 Long-Term Review

There have been very few truly unique features on compound bows in recent years and now there is one less…Prime has done away with its double side-by-side cam setup and introduced the new Inline cam system that you can see here on the Prime Inline 3 I've been testing for the past few months.

Before we dig too deep on the cams, let’s talk specs. The Inline 3 has an axle-to-axle length of 33 inches, brace height of 6.5 inches, and a rated speed of 337 feet per second.

Back to that new Inline cam system. While it may look like a traditional compound bow cam design, Prime did build some interesting technology into it. Prime says it is the first ever cam system that balances cable load during the draw cycle. During the draw, the heavy cable load track moves towards the center of the cam, which brings it inline with the string track. This is supposed to keep the cam balanced, but I’d be lying if I said the description goes slightly beyond what my non-engineer brain can fully comprehend. If you are really interested, Prime does have some videos on its YouTube channel that do a much better job of describing it than I can.

The new cam system also simplifies the string and cable situation. With the Inline cam, Prime uses a traditional three-piece string/cable setup, rather than the 7-piece offering on the Nexus 2 I shot last year.
