Geo-Line Overshot and Dry Hole Device
The TECSO Geo-line OVERSHOT, offers greater security recovering the inner tube assembly from the bottom of the hole.
Its rugged construction and design, ensuring maximum efficiency in liquid filled holes.
On dry drilling, or severe loss of water, the Dry Hole Device is used for lowering the inner tube to its working position.
The Dry Hole Device and Overshot work in combination: the catch sleeve is unscrewed from the Overshot so that it can be fixed to the Dry Hole Device.
