Michael S.wrote a review of CAMP USA - Cassin Alpinist Pro Auto/Semi-Auto Crampon on December 8, 2018
Familiarity: I've put it through the wringer
TL;DR: The second best ice climbing crampon I've ever owned, ever so slightly behind the blade runner, but I like certain features of this better.
I purchased this crampon when it first came out, and have used it for about a season now, in terrain up to WI4+, but not on any real mixed terrain.
My review is based on my comparison against the other crampons I have owned/worn:
Black Diamond Cyborg
Camp Blade runner
This crampon borrows a lot of the features of the blade runner, and improved on some of them.
Unlike most crampons on the market, the Alpinist Pro is a constructed of only two pieces - a front part (front points, secondaries etc - painted orange) and a combined heel-linking bar part (painted black). It's two piece construction is stiffer than any 3 piece crampon I have ever tried, which helps in steep terrain.
It fits asymmetric modern boots very well, without the front points being aligned - "toed in" which I have found with other crampons (Lynx), so when you kick the ice - both front points penetrate consistently and evenly.
The heel-linking bar part is not flat like most manufactures , but has a lip and engages the heel tread of the boot, helping to drive the crampon into the ice. Additionally, the heal-linking bar part also has small tabs turned upward on the side (like almost all other crampons) which was lacking on the blade runner, and keeps the heel of the boot in place with greater consistency than the blade runner.
The linking system is a real pleasure to use, and makes adjustment very easy and can be used with gloves - this is a big improvement over the blade runner, which was difficult to adjust with gloves.
Camp has also redone the heal bail clamp of this crampon, getting rid the screw adjuster that is universal in almost every other crampon, and opting instead for 3 bail locations, low, mid, and high. While you lose some of the micro adjust-ability, when combined with the linking system, you can still achieve excellent fit and confidence inspiring attachment.
The anti-balling plates are about as functional as any anti-balling plates it seems. They work well 90% of the time, but under just the right conditions, you'll be stuck knocking snow off of your crampons.
The Alpinist line of crampons has modularity - the Alpinist Auto is more of your classic mountaineering crampon (horizontal front points). If you purchase the Alpinist Auto - and get the Alpinist Pro front part, you now have two crampons for the cost of 1.5 crampons - similar to following Petzl in this regard. However - you cannot (to my knowledge) buy just the Alpinist Auto front part - which is a bit of a drag.
Less than Good:
The price point is expensive for a crampon that you cannot convert to monopoint, and some of the reason that I like it less than the blade runner.
Also the while the secondary points are very well placed on this crampon, they are not quite as good as the blade runner.
These are a little heavy to be sure - at 2.2 lbs - there are lighter crampons on the market.
For these last three reasons the Alpinist Pro loses a half star.
