Even with a moving animal the Accu-Lock II System calculates and holds the animal's true weight without annoying digit jitter! Just walk the animal on the scale and in approximately 10 seconds the Accu-Lock II has locked on the animal's actual weight.

This makes getting animals on and off the scale much easier.
