The grader works smoothly and stays at the right depth in the water. I adjusted it to 0.75″ and it correctly separated fish by size. The aluminum body feels solid and the lever is easy to use. No issues after several weeks of daily use.

Great for a fish processing setup. The floating design keeps it stable, and the size adjustments are precise. I use the G1B for smaller fish and it handles the gradations well without damaging the fish.

I’ve used this for over a month in a commercial fish market. The locking mechanism keeps the setting in place, and the bars don’t wear down even with frequent use. Made in USA — a quality product.
