Sonic Dual Tube 60 (SDT60)
Needing a larger sample? Want productive, efficient time in the field? Tired of handling larger casing with conventional sonic methods? Geoprobe® has developed the SDT60 sampling system… A Dual Tube System that advances our 6 in. casing and collects samples without the overcasing conventional method. The core barrel is advanced simultaneously with the outer 6 in. casing. Our 2.25 in. inner rods remove the core barrel and the 4.3 in. diameter sample is collected into core bags. By advancing the casing and inner rod string together, you achieve an increase in productivity and minimize the handling of casing.

- Continuously Collect 4.3 in. Diameter Soil Cores
- True 6 in. Diameter Borehole
- Set 2 in. Monitoring Well Through 6 in. Casing
