Question about portable scales

Lol, I dont know who made them , MD500's were the scales we had before the PAT's, they had a dial , but no zero knob..I hated them cause they were so tall , it was hard for the trucks to climb up them , it was like putting a chock in front of the trucks wheels.
The "newer" ones "PAT's" were electronic and had a digital read out. They were about an inch thick so they were much easier to get a truck on.. They were just a pain to keep the batteries charged. The PATS zeroed them selves out when turned on , if there was an error , it displayed an error message.

 

How about just not messing with them and leave us heavy trucks alone. Go get the guys with only one brake that works, which around here seems to be the guys pulling the containers with the $500.00 trucks.:smt064
