Thanks for sharing Cutty.
That new option hasn't made it here yet, but we do get a good price on the existing CoCoRaHS approved http://www.shopcocorahs.ca/
How would it do for snow core sampling?  We had snow/ice combination a few days that resulted in ice/snow of over 5 cm and it was very difficult to get the current outer tube to get through the crust.  Looks like the new type has some vulnerable parts on the side.

Enjoy,
Paul

I did not have the opportunity to try a snow core. Indications from others are 'no problem'.
Not  sure what would be 'vulnerable' parts on the side.... as I said when I summed up my testing:

"A comment on the material: Based on specifications, I believe the material used will have longer clarity life using its UV enhanced material. This state-of-the-art construction almost felt 'flimsy' at first, because of appearance and material, compared to the 'other name', but it is at least as strong-- maybe stronger. Impressive."
...And it's breeze to get out of bracket if freezes... gentle tap got 'er loose 4 times.
