3" Oyster gauge

This 3-inch oyster gauge is designed for grading and market sizing of oysters. Precision-cut from durable stainless steel, it provides a quick and consistent way to verify oyster size during harvest, sorting, or pre-sale grading.

The gauge is clearly marked Ø3” for easy identification and features a flat, lightweight profile for comfortable one-handed use. A lanyard hole allows it to be clipped or secured for quick access while working.

Note: The side flange of this gauge is slightly smaller than standard, which does not affect the accuracy of the 3” opening but may be noticeable in hand compared to other gauges. This is a cosmetic/design variation only and does not impact function.

Built to withstand marine environments, the stainless steel construction is corrosion-resistant and easy to clean, making it suitable for regular use in aquaculture settings.
