Usher in the new age of thin crack protection.

Thanks to its incredibly narrow head profile, the Black Diamond Camalot C3 fits in places where other cams just don't stand a chance. As the cams contract, they overlap with each other's stems to increase surface area and holding power. The C3's sizes go way below the standard to help you protect ultra-thin aid lines and cutting-edge trad climbs. In addition, the C3 uses a unique stem design that blurs the lines between single and double stems. A shroud protects the tiny cables from getting jacked while maintaining the flexibility to handle funky placements where stiffer cams lever out and leave you unprotected.

  • The C3's head is 30% narrower than any three- or four-cam unit available
  • Features interlocking lobes and an internal dual-stem design to achieve its slim profile and smooth action
  • Independent trigger springs allow each cam lobe to operate freely and to fit into tiny irregularities in the crack
  • Cam stops make tipped-out placements more secure
  • The large thumb loop makes this cam easy to place when you're pumped stupid and provides a short clip-in point for aid climbing

Here's what others have to say...

Not bad but others are better

  • Familiarity: I've used it once or twice and have initial impressions

These are nice cams and will do the job. But they have quite a stiff body (yes, the plastic case does help protect them) and pretty stiff trigger pull. In retrospect, I'd just get Mastercams instead.

Get the X4s

  • Familiarity: I've put it through the wringer

Unless you are going with the extremely small aid cams, get the X4s. Their range is larger, they have more flexibility, they have four lobes instead of three, and the triggers are easier to pull, especially when you're getting pumped. If you don't want to spend a measly $6 more dollars for the X4s, get the Metolius Master Cams.

Don't get me wrong, these cams work great. I just believe there are others that are better.

Like it

  • Familiarity: I've used it once or twice and have initial impressions

I bought a 2 recently. I've only placed it a handful of times but defiantly like the feel of it. I really like the plastic covering that protects the stems. I am planning to get the rest of the set soon.

OK. I'm fairly new to trad and have been using the BD C4s and I love them. When would you use the BD C3s. Is it only for really thin cracks?

Best Answer

Size 1 and 2 are getting close to finger crack territory, but for the most part these are intended to protect climbs using cracks too thin for handholds. The #000 is actually so thin that it's not rated for falling on, only aid climbing. It's entirely possible that you'll never need gear this thin.

Great cam

  • Familiarity: I've used it several times

These cams are amazingly lightweight, which was actually a little worrisome at first, seeing as how they might be saving my life!!! However, just like all of Black Diamond's climbing products they work outstanding. Very smooth trigger and the colors are very vibrant, which makes them easy to distinguish size. Highly recommend these.

Does it get any better?

  • Familiarity: I've put it through the wringer

black diamond. what more could you want. these are great cams and theyre cheap. i always double up on the 000 but other than that theyre bomber.

  • Familiarity: I've put it through the wringer

I always considered these cams as more of a 'peace of mind' rather than 'bomber, i can drop a car on this piece' type of placement... Then I cam sailing off on a 000 (rated for aid only). I wish I had a picture of my face when that thing held! I have fallen on these cams a lot, more so than my C4s, and have been caught every time. I love these cams and always carry a set with me. I cannot compare them to aliens (never use 'em), but I really like the guys a lot. They were a bit tricky for me to get used to size wise, but I think that is the nature of small placement. The wire guard is nice for horizontal placements making these durable cams. Way to go BD! I highly recommend these cams!

Not impressed.

I purchased a #1 about two months ago and due to a lack of climbing partner, this has sat in my closet unused for that time frame. I pulled out my rack last night in prep for a climb today and during my pre climb gear packing / inspection, I noticed the wires are beginning to oxidize and the movement inside the housing feels stiff. This may be solved with some cam lube but If this is how the product holds up prior to it's first use, I will not be putting my life on those lobes...

hard to trust at first

  • Familiarity: I've used it several times

these are hard to trust at first because they are soooooo thin. but once youve taken a fall, youll notice that they are ass strong as the big ones.
help to save weight because on easy climbs you can allways find a spot to place these

super bomber

  • Familiarity: I've put it through the wringer

I have the purple and the green, and I place them before the equivalent Metolius sizes. It is hard to believe how well the tiny purple camalot C3 can keep me off the deck!

hoooo dilly

  • Gender: Male
  • Familiarity: I've put it through the wringer

Took a 15 foot whipper on two red C3's in a thin roof crack, only one held, so that's neat. They're a bit goofy to place to make sure you check the lobes!

Trying to decide between Metolius TCU's...

Trying to decide between Metolius TCU's and BD C3's....usually climb in southern UT and Big Cottonwood Canyon... Already have some Camalot C4's

Its always a good idea to have a couple of different types of units on your rack. It seems that lately I'm meeting folks with significant brand loyalty with their cams, but the truth is different types of cams will sit better in different types of cracks. Get a couple of each and figure out where they work best, then decide on how to beef up your rack later.

Ode to a Camalot

Dear Camalot C3s, you give me pause
I didn't see sketchy placements as a clause
In the contract I signed by buying you
After each placement, I feel blue
Will you hold me? Sometimes, I assume.
But "sometimes" rather brings me gloom.
'Cause sometimes really isn't good enough
My life rather means too much to slough
Camming duties off on you,
When I have no assurance that you'll hold true.
Cool engineering? Check! You've got it
But when I'm run out, that just doesn't cut it.
Will you fit in that pocket? Why yes of course,
But it's quite likely that you'll blow with force.
Is there a spot on my rack for you?
Yes, but it's small, perhaps just one or two.
When it comes down to it, I'd rather have Masters or Zeros
They give me more bang, por mis dineros.
So if you're looking to buy a micro cam, or two,
look elsewhere, that's why I wrote this review.

yeah, the anti-cedar wright, his reviews are usually raving about the product. Its nice to see some poetic criticism :)

The action started out super stiff, but after a few uses these thing feel great! They're amazingly bomber, which is nuts based on the size. I'm a fan!

Alright, but there are better options.

The first thing I thought when I got my yellow c3 out of the box was "wow, this is an incredible piece of engineering." I still think that, but after having placed it a few times, I find that I'd almost always rather go with my friend's red WC Zero. The cam lobes are great with how close together they are, but that also makes them less stable, which scares me a bit. While I would say that if you have a big rack, and you have the money, it might not be a bad idea to have a couple of these guys for awkward placements, your money would be much better spent on a set of 4-cam micro cams. I love the zeros, but the master cams are pretty stinking awesome as well.

Great for the size

These cams perform really well in the finger to tips size and the narrow head allows for placements in limbstone that a four lobe and many other three lobers just don't fit in

So bomber and so good!

Got to use these for the first time switching leads and I am amazed. I took a lead fall on a #1 and my confidence in these pieces grew even more! Definitely try these.

Protection for your protection

I was a bit skeptical at first regarding the rubberized center portion and internal wires on these things when I started playing with them a while back. After loading the cams over edges repeatedly during aid pitches and free climbs and then having the whole unit rebound to its original shape and having no kinks or damage I knew these were genius. I use them in conjunction with my mastercams in the smaller ranges of my rack and love them as aid pieces.
