Last fall my partner bought me 4 cams that were on sale. In reading all the discussions about cams I started wonder what kind I had. They are obviously metolius and obviously 1 to 4 but I can't tell if they are tcu's or powercams. although I suspect that 3 are one and the #1 is another.
Just what is the difference both in how they look and their performance characteristics?...The metolius website was distinctly unhelpful.
And this is the year I learn to use them...woot!

TCU = tri (three) camming unit. Tcu’s have 3 cam lobes that make for a narrower head width, allowing them to fit in shallower placements. Power cams have 4 lobes and greater holding power. Those look like the old generation cams, with the blue being the power cam.

Disregard any flames ... asking questions legitimately is a good thing.

three cam unit
the number 1 is a power cam
the only difference between the cams is how small of width that you need to place them.
some people say that 3cu's rotate more than 4cu's, but if you sling them properly - it won't be an issue for you. Those are some hard cracks you are going to be climbing with those!!
have fun!!

as a side note, i ididn't pay attention to the pic, but if you have the "rangefinder" dots on any of your cams, don't cam them at the larger end of the green or you will be risking, leaving it there permanently hehe.. good luck!

Tiny climbing unit?
Terrific crack usage?
Tensile cord unification?
Tremendous cam user?
Tasmanian cockatoo utility?
Tri-state community underwear...
Why am I starting to think im might mean "three cam unit" or something like that. You'd think they might actaully mention that on the website...
So if I was to get the 0 or 00 is weight the only difference?
edited to admit my reply took too long...

Do you mean powercam vs. tcu? The 0 and the 00 are for extremely narrow placements bordering on aid climbing.

Or, in the alternative, aid climbing.

Bah! That does sound pretty dumb. Meant to say more usable in aid climbing situations....unless you're truly badass.

So yur sayin' that to really spray whilst at the gym I need doubles of 0 and 00 but I should keep them hidden with my smelly socks at the crag!
Thanks all... I'm gonna take a course this spring and then start adding to the rack based on what I learn about the Canadian Rockies...

Did Metolious make 00 and 0 Power Cams in the older style? I'm thinking in the old style they only had the 00 and 0 in the TCUs.
I use both the 00 and 0 for free climbing placements. I have fallen on the 00. Without looking at a spec chart the 00 and 0 are rated to 6kn right?

00 is smaller than 0 (slightly).

I think I remember that being the case. Can't be sure though.
