You can see the thought pattern that occurred when these were designed...someone probably found themselves on a route with a cam that was the wrong size, and thought...lets make one that does more sizes! fair enough...but a really bad idea!!! Let me explain:

So, Omega Pacific have been known to advertise this as being great because instead of having to carry 3 different sized cams, you only have to carry one...but what happens when you've placed it? you don't have a cam anymore...whereas if you had 3 different sizes, you still have two left. Its simple maths really! So, the way around it is to carry 3x link cams...but that's un-doing the weight saving, and costing you nearly double what 3 regular cams would.

How can this make sense!!!?

Admitedly, they might be worthwhile carrying if your leading a group on a scramble or similar, where you might be putting in very occasional gear to protect yourselves moving together, but as a climber, I don't see much use for this 'innovation'?

so, you won't see me carrying them on my harness any time soon

Omega Pacific have designed a very unique camming device with the Link Cam, but is it worth having? The advantages on the face of it should be clear. The cam lobes are split into three sections, allowing them to 'unfold' when the trigger is pulled. In theory the cam offers a range that vastly exceeds any other camming devices on the market. This sounds brilliant, however is it all its cracked up to be?

I bought one of these cams in the US a couple of years ago, a number 1 (the red one). It was bought as a novelty item, and with its price tag an expensive one at that! The advantage of having a huge camming range in one unit has been useful on a number of occasions, notably when at a crux or difficult section where gear needs to be placed quickly! Rather than risking the right size in a standard cam and hanging around for longer, the link cam can be picked up and placed quickly in a bigger range of cracks. Having said that, i have never got it to seat as well as other standard cams, and the confidence it provides cannot compare to other brands. The company says itself that placement of these cams must be very carefully done, as any shock movement when loaded can damage the cam and compromise its strength.

Overall, i would not reccomend these camming devices, for the price the unique features are not worth it.
