What to say that hasn't already been said. . .
Whether you're getting pumped out of your gourd on some splitter hand crack or you're teaching a friend how to trad climb and anywhere beyond or between, black diamond C4s are the way to go for all your camming needs. The Camelot is a tried and true necessity for everyone's rack. If you're pumped out of your gourd while placing and you end up whipping on one of these you'll be sure glad to doing so on a C4. They're the first cams I ever built my rack with and even though I love the Z4s for smaller sizes, these are always my go to for the bigger ones. Definitely worth adding to your quiver!
A Staple For A Standard Rack
The C4 Camalots are a great addition to any rack, especially when just getting started with trad climbing. A smooth and consistent trigger action, ability to hold in a variety of rock, and a years of field testing inspires confidence in these cams. My favorite aspect of these over others is that Black Diamond can resling them when the nylon wears out, so you can continue to safely use them for a decade plus! They are not the lightest cams, but unless you are pushing grade or alpine climbing, you won't notice. These are and will continue to be the foundation of my rack.

Top of the pile!
No matter what kind of trad climbing you are doing, the Camelot C4 is the workhorse you need! Always there when you need them the BD C4 is at the top of the pile!
Take the whipper
Solid cam ! Easy to place , when placed right very safe to fall on .
The standard for a reason
i’ve used dmm, and wild country cams before and these are just the best. The trigger feel is unmatched and the weight is also amazing. The non extendable sling doesn’t bother me either i’ve used them before and they’re just not that convenient.
The standard
Everybody knows the Black Diamond C4’s are the standard in cams. It’s like the Toyota 4Runner your dirtbag friend lives in. A constant. These updated cams are great and you can tell that the first time you hold them.
Not Good
This .5 has seen next to no use...has been placed maybe 4 times. Never been whipped on and probably not even weighted. The spring has come out of its small hole on the lobe. Called BD customer service, rep says "yeah, you should just be able to push it back in" Well, 10+ attempts with needle nose pliers and tweezers, no luck. No helpful instruction from BD.
The New Gold
The refreshed/redesigned C4s are some of the best pieces of protection you can place in a crack. Or a pod. Or a constriction. Get something with a more flexible stem for horizontals. Lighter than the previous generation which brings them close to the ultralights, and with better predicted durability it makes them the optimal choice in my opinion. Trigger keepers on the bigger sizes are a super useful upgrade. These should be the staples that you build your rack around.
#2 added to the rack
I just purchased the first few pieces of gear for my mega rack (one day these pieces will all be welded in the walls of el cap) Don’t really know how to use this thing or what it does, but it’s really shiny right now so I think i’ll probably just leave it on my shelf for a few years so I don’t scratch it up.
Sending It
After years of borrowing my friends gear I finally decided to grow up and purchase a set of my own. I am extremely happy with the quality of the BlackDiamond Camalots and look forward to the next big adventure with them
