The Metolius Master Cam is not only one the best small camming devices for the money, it is one of the best smaller s.l.c.d.'s (spring loaded camming devices) at any price. It wins our Best Buy award because it scores almost as high as the Black Diamond Camalot X4 but is $20 less expensive. That adds up to a lot of savings when you're purchasing an entire set. It also may be more durable than the X4, adding to its long-term value. It was the first climbing cam to seriously challenge the CCH Alien for the title of "best cam for shallow and awkward placements." It has a narrow head, which makes it easy to get in pin scars, and it comes with all the other benefits of a single stem unit.
While the Black Diamond Camalot C3 has an even more narrow head, it also is not as stable or as good in awkward placements. The Master Cam is quite flexible, too, although not as much as the Aliens. So overall, it does a lot of things well without having any big downsides, which makes it an overall solid cam. Best of all, it is affordable and relatively easy to find (not always the case with Aliens).
