What is a "core shot?"?

Question

i unfortunately ran over a few branches and rocks with my all-mountain rossi skis.

i found a 1"x1" scratch that was not too deep on the front base of one ski and another deeper (maybe 1mm deep) scratch (on the base) under the front binding piece of the other ski.

the next time i went to the snow, i found one of my skis catching noticeably.

i took the skis to a shop and had them do a major tune. the tech that took my skis told me that they will all be fixed; the deeper one fixed with a bit of ptex.

when i picked them up, i didnt have time to check the skis but i can now still see a bit of the scratch.

my question is, a tech mentioned when i was picking up the skis that the ski with the deep scratch has taken a "core shot"; what does that mean? will it affect the performance? (the only damage that i can see is the remaining dept of the scratch) what can i do to remedy the situation?

thank you!

Answer 1

Ok so basically there are 3 main parts of a ski (I'm only talking about the actual plank, no bindings or anything)

3 Parts: (in order from base to the design)

-the Base (plastic)

-the Core (wood or fibreglass usually)

-and the design bit on top with all the graphics

When the technician refers to a "core shot" what he means is the rock carved a gash into your ski that scraped all the way through the base and into the core. And since the base + core are made of different materials you can't just do a simple p-tex job to fill in the gap. It's never happened to me so I don't know what the procedure is called or how it works.

But that pretty much explains what a core shot is.
