Don’t just take our word for it, though. Read what some customers had to say about our products. 

James Boylan - Boylan Oysters (South Australia)
I’m impressed! We can bring in our product and get it straight out again. It’s better than hand grading by a country mile!

Arno Bros – Great Bight Oysters (South Australia)
The SED machine takes the stress out of grading and speeds it up.

Steve Pope – Biomarine (New Zealand)
We purchased the machine to save labour – it has done just that.

Tony Byrne – Greenfields (Tasmania, Australia)
Performed to our expectations and above.
Very happy that all four components of our system arrived and were operational in a short time without hitches, - excellent.

Brian Leahy – St Helens Marine Farmers Rep (Tasmania, Australia)
Provides extremely accurate sizing and counts at all stages ensuring better growing / condition / quality - and therefore lifting overall production which uses up the surplus labour.

The grader has consistent throughput of about 1200 dozen – 1400 dozen per hour.
