When stacking core trays containing fragmented, protrusive core, there is a need to allow enough clearance between the core and the tray stacked on top. The Discoverer® 'Flat Bottom' S3 Core Trays/Core Boxes have increased channel height to maximise the stability of trays even with fragmented core.

Core trays which don't run smoothly or bump on roller racking are difficult to work with and disturb the core. The patented unique flat bottom structure has been developed to ensure smooth movement on roller racking and ball transfer tables in any direction or at any angle, without disturbing the valuable core samples inside the tray.

The unique stacking design means that the trays stack perfectly on top of each other without the tray above touching the core in the tray below. All Discoverer® S3 trays have the same footprint so you can stack the different sized trays (NQ, HQ, PQ) on top of each other when changing the core barrel size within a drill hole.

From any angle, from any side and to suit every single natural lifting position for any user, the 360° continuous grip bar makes the heavy lift simple. Whether pulling the tray along roller racking or lifting trays onto the vehicle, you can get a grip on every side of the tray with absolute ease. The grip bar is generously sized to suit even XL hands, and especially molded for comfort, for both male and female geologists. 

The bold start indicator gives clarity to drillers, reducing potential errors when logging the core. Clip-in core markers are designed to optimise the use of the tray. The markers are colour-coded to match the trays and the top surface is etched, allowing you to record notes. Built-in ID tag holders are now moulded into both the front and the side of the trays. These provide a permanent record of tray contents.
