The DeviGyro RG40 Standard survey assembly is suited for most types of in-rod applications. It comes equipped with our patented adjustable centralizers which cover a wide range of rod diameters and profiles, while still supporting the high-speed continuous survey operation the DeviGyro has become known for.

As with all DeviGyro running gear configurations, due to Devico’s patented antenna technology, the communication between the DeviGyro RG40 Standard instrument and the handheld device is completely wireless and functions through the pressure barrel. Enabling quick activation, data transfer and download.

Designed with various drilling environments in mind, the DeviGyro RG40 Standard offers a user friendly, reliable, and robust survey assembly. Available in a compact or extended kit the DeviGyro RG40 Standard is easy to use, adapt, handle and transport from site to site. Making it the go-to solution for a wide range of drilling applications.

Frequently asked questions about DeviGyro RG40 STANDARD

What downhole survey tools do Devico have that are compatible with V-wall rods?

The DeviGyro RG40, DeviGyro Overshot Xpress and DeviShot products are available with V-wall compatible centralization.

See answer

What downhole survey tools do Devico offer for diamond core drilling?

DeviGyro RG40, DeviGyro Overshot Xpress, DeviFlex RAPID and DeviShot.

See answer

How long is the DeviGyro RG40 Standard when fully assembled?

Compact (without extension bars) 1.5m. Extended (with extension bars) 2.2m.

See answer

Is the DeviGyro RG40 Standard compatible with V-Wall rods?

Yes, it is compatible with standard, V-Wall and W-Wall coring rods.

See answer

What running gear is provided with a DeviGyro RG40 Standard kit?

A DeviGyro RG40 Standard Kit includes a DeviGyro Instrument Kit (Instrument and Android phone), an RG40 Running Gear kit (pressure barrel, centralizers, bull nose, swivel and spear head/wire adapter and 3 v-stands) and a DeviCounter Kit (DeviCounter, Clamp and Android phone).

See answer

Is the DeviGyro RG40 Standard North Seeking?

No, the DeviGyro is not north seeking. It is a high precision, continuous rate gyro using north seeking principles and proprietary algorithms to determine the drill hole path from a known direction. Most continuous north seeking gyros operate in the same way. They determine a start direction and then measure the “rate“ of change from the initial reference.
