The new Dual Mast Terrier from Dando Drilling International is able to use us a wide range of techniques in the same borehole. 

The drill rig is designed to trip out drilling equipment in 4-meter lengths using the telescopic winch system.

Drillers can use the Terrier drive sampling system along with the Terrier rotary drill alternately without having to change masts.

The machine hydraulically slides the drive sampler or rotary drill into position above the borehole when needed. It is designed to trip out drilling equipment in 4-meter lengths using the telescopic winch system.

The versatile drill rig has a small footprint that makes it easy to transport and operate in tight spaces.

Dando Drilling International, based in West Sussex, England, manufactures rigs for water well, mining, geotechnical and geothermal markets. For more information, visit www.dando.co.uk.
