The WDT is a standalone wireless depth tracker with a fixture for mounting on the drill rod collar. The system is built for drillers and is robust, reliable, and simple to use. The WDT can be operated directly from Inertial Sensing’s Surveyor software for continuous mode gyro surveys. It provides real time depth readings, stored and processed by the field computer. It can also be operated individually using a smartphone app.

• Bluetooth communication
• Long battery life
• Light weight
• 0.1% depth accuracy
• Up to 12 mm wireline diameter
• 100 m/min wireline speed

A lightweight tripod allows a single operator to performa survey in vertical a borehole when the drill rig has already left.

The kit consists of:
• Detachable pulley
• Telescopic legs
• Adjustable ties
• 3 ground anchors

The ADW600 is a compact and portable winchfor borehole surveys and logging. It is designed for 600 m of 1/8"-wire rope.

The main components are:
• Helicoidal spindle for automatic laying of cable on drum
• Electronic depth encoder with display
• Frequency controlled asynchronous electric motor (0.75 kW)
• Electric motor brake that keeps the wireline stillat stations
• 600 m of stainless-steelwire rope

A version for geophysical borehole logging with 600 m of 1/8"mono-conductor wireline cable and mercury slip rings is available on request. Contact info@inertialsensing.com for any special requirements.

For oil & gas, geothermaland hot mining applications a heatshield is required. We supply a range of heatshields custom designed for our gyro survey tools. We use only the highest quality products from National K Works.
