Grow Out Tumblers

The Zapco Tumbler is perfect for growing out spat from 3 mm to fully grown oysters.

This unique design helps the oyster develop a uniform shape and increases the growth rate in the early stages of growing from a spat to an oyster. It also reduces the risk of over catch and fowling reducing the work load.

New and Improved for the 2020 Season

New blow molded Floats that can be handle pressure up to 6 meters in depth
New door design improving the strength of the closure latch
Redesigned float clips that are inserted into the floats so the tumbler can stand up straight without rocking and also will not come out.
