Sand augers use a closed bit design with a restricted opening to prevent the loss of sampled material during retrieval. The inner edges of the sand auger bits touch at their mid-point to make the sand auger more reliable in loose, unconsolidated soil conditions.
Please make sure any AMS samplers you intend to use together share a common connection type.
This auger is specially made to order; there are NO RETURNS for this item. **Sizes listed are the OD (outer diameter) of the auger cylinder**
