re: scale - it's just a digital fish scale with a hook I got at a sporting goods store, works great brand name is Quarrow - this one: https://www.basspro.com/shop/en/quarrow-...hing-scale (not sure why there are bad reviews mine has been solidly reliable for over a year.)
re: bear can - Bearikade does rent the other models. Also, that is a rather large densely heavy object, would be somewhat challenging to balance that on the other pannier particularly as it changes weight daily. As you said, might want to consider carrying that yourself; and then you could offload more static weight items to the goat(s) so you're not rethinking the packing every morning, would be a bit of a time saver.
