Kinda hard to invert the big tube for a core.
My Stratus lives indoors in the cold season, only let outside to take cores. Despite the claim of safety, I'm not confident that it would survive a heavy rain followed by freeze. Two years ago we had a 2"+ downpour while we were in SNJ for Christmas. When we got back, the 5-gal used for winter precip held an ice-discus that had bowed the bottom nearly an inch without breaking it - returned to normal once emptied and warmed. If there's much over 11" on the board I'll take the core in 2 steps, usually by carefully sliding my snow shovel (uncurved blade) at the halfway point, pushing the tube to contact and then very carefully lift/invert the shovel while holding the tube, taking care to swing away from the snowboard. I'll have a 2-gallon wash pail to dump the 1st partial core and just put the tube upside down into the pail with the 2nd. I do the melt/measure like dendrite.
