Camalots are designed to provide protection across the full spectrum of crack sizes, from small incipient seams, to perfect hands, to full-on offwidths. Camalots, Camalot C3s, Camalot X4s and Camalot Ultralights each have their own unique advantages, and a well-rounded rack will likely contain some or all sizes of each cam. Check out the chart to see how the members of the Camalot family overlap.
Camalot Ultralight .4
On fast-and-light missions and smash-and-grab ascents when weight really matters, the Black Diamond Camalot Ultralight presents a 25% weight savings over the Camalot. With sculpted lobes that account for a portion of the weight savings, the Camalot Ultralight features a dyneema cord in place of a cable with all of the same strength you rely on. A double-axle design allows for the widest placement range possible for each cam device, and color coding makes for easy identification when quick pro is paramount. When light is right, the Camalot Ultralight is essential.
Double-axle design offers widest range for each cam unit.
Dyneema core stem design is strong, durable and low-profile.
14mm dyneema tape sling.
Ergonomically optimized stem and thumb loop for surgically precision placements.
Color-coded for easy identification and wide range of sizes.

Cam Range (mm / in)
In millimeters and inches, the maximum dimensions of the cam lobes when shut tight and fully extended. Since the "usable" range is so debatable, all manufacturers now list the full dimensions to avoid confusion.
If a manufacturer lists the usable range, we'll include it here as well (this is now very rare).

For the last few years, the much-loved Camalot C4 has set the standard for modern spring-loaded camming devices, with snappy trigger action, a great placement range, and top-notch durability. The new Ultralights are all that with about 25% less weight for the whole set from .4 to #4. “Now that I know how light a cam can be, I don’t know if I can go back,” said one tester who plugged them from Eldo to Smith Rock to Indian Creek. In order to cut ounces, designers selectively removed metal from the lobes and replaced the wired thumb loop with Dyneema. The result is a featherweight cam with only a mild sacrifice in strength—each cam is rated about 2kN less than its full-weight counterpart, but that leaves it plenty strong for both free and aid climbing. Alpine testers appreciated the weight savings for big days, and moderate tradsters were able to take all the cams they needed for peace of mind without being weighed down. The savings are most apparent in the larger sizes where there were more spots for metal removal. A .4 saves about 22 grams (.78 oz.), but a #4 saves the equivalent of an entire .4 cam (2.2 oz.). They are quite a bit pricier, but you get what you pay for.
