The Reutech Digital Compass (RDC) delivers precise Dip & Dip Direction or Dip & Strike measurements at any angle with a single button press. Designed for efficiency and accuracy, this handheld device streamlines geological mapping, eliminating tedious setup procedures. Uniquely tagged measurements are stored on the device and seamlessly transferred via Bluetooth to a PC when required.
Conventional compasses often slow down the mapping process with repetitive steps and manual note-taking. The RDC reduces these tedious tasks, making levelling quicker and capturing measurements more straightforward. Each reading is stored automatically with a unique tag, eliminating the need to stop and record results by hand. With its intuitive single-button interface and OLED display, the RDC allows geologists to measure, select, and cycle through options with ease. The result is faster mapping of multiple structures, improved accuracy, and more efficient use of time in the field.

The RDC connects wirelessly to a user-friendly Windows 10 application. The software provides full access to device information, displays individual measurements, and enables users to apply either True or Magnetic North corrections. Data can be exported in CSV format for seamless integration into geotechnical software, supporting efficient workflows and reliable reporting.

A standard CR2450 battery is used.
The lifetime is dependent on the measurement and Bluetooth usage, which makes the lifetime of the battery difficult to specify.
It is important to keep these functions to a minimum when not taking measurements or downloading data.
There is a quarter turn battery cover on the rear portion of the device.
Clock-wise to close and anti clock-wise to open.
Do not over turn or the locking mechanism will be damaged.
Once open press the battery retaining clip to the side away from the battery to release it.
Insert the new battery making sure it is clipped onto place correctly before closing the cover.
No.
Both options are available but not at the same time.
The user is able to set the magnetic declination via the Manager PC application.
A value of 0 (zero) indicates no magnetic declination.
On the device menu go to Calibrate under the Settings menu and do a long press on the red Push button to enter the calibration procedure.
Hold the device in your hand and move it around in a figure of eight movement for a minute or two to generate the calibration data.
Once the device has sufficient data it will perform the calculation and exit the calibration menu.
The accuracy of any measurement is dependent on external magnetic influences.
This could be from metallic objects in the vicinity and includes wrist watches and cell phones.
This is no different for an analog or digital compass of any type.
The user should achieve better than ±2⁰ accuracy with minimal external interference.
The user can enter the magnetic declination in the software, and when the data is saved it is corrected.
It is affected in the same way an analogue compass is. The analogue compass needle will move but the perceived movement will not be as noticeable as small changes are difficult to see. On the RDC unit, the numbers will be changing dynamically which is much more visible to the observer.
Remove the battery to reset the device.
Remove the battery to reset the device.
The stored data on the device can be cleared from the device via the menu or via the Manager PC application.
The device offers three measurement options:
This setting is available in the menu under Mode, Display.
We use industrial rated components at certified to -40 °C.
There is no need to use the PC’s Bluetooth menu for this.
To pair you first need to enable BLE on the device.
Run the Manager PC application and click on BLE Connection and follow the steps.
Once the device is connected to the Manager the icon on the device will change and the Manager will show the connection status and device information.
No need, this is done by the device and Manager PC application.
Enter the menu on the device and navigate to the Bluetooth menu option.
Select BLE On and then execute with a long press.
A radio icon will appear on the device display.
Once the Manager PC application has connected the icon will change to the standard Bluetooth icon.
The menu is accessed by a LONG press on the Red pushbutton once it has been woken up.
A LONG press either enters the Menu option or confirms the option selection.
A SHORT press cycles through the menu options.
The base of the unit is the reference, and the body can be at any orientation, typically the most comfortable position for measuring is used in each situation.
To download data enable Bluetooth on the RDC.
Connect to the RDC via Bluetooth on the Manager PC application first.
Follow the procedure in the manual to read and save the data stored on the device.
Each measurement is numbered and has a date/time stamp.
When this data is saved to the PC it is in a comma delimited CSV format.
The data is exported as a CSV file from the Manager PC application.
12 months carry-in warranty.
