I've used this one a lot recently.

RoMech 660lb Digital Hanging Scale with Cast Aluminum Case, Handheld 300Kg Mini Crane Scale with Hooks for Farm Hunting Fishing Outdoor (Orange) https://www.amazon.com/dp/B08669YYV7/ref=cm_sw_r_apan_glt_i_ZR1Z3JMY19RFMP59SMRB?_encoding=UTF8&psc=1

We use it on our rucks, and most frequently, on sandbags full of food for a food drive ruck. Our weights were verified by the food pantry after it was over.
