The Carlson Explorer II is a rugged data collector designed for field survey work and is commonly paired with Carlson SurvCE, a survey data collection software ideal for GPS and Total Station operations. The unit combines keypad and touchscreen input, features a Windows CE .NET operating system, and is rated for harsh environments, making it suitable for demanding survey conditions. It has a 320x240 pixel QVGA color display that is readable in bright sunlight, and it uses an Intel XScale processor for quick calculations and reliable performance.

Bluetooth and CF Card Support

The Explorer II supports a CF (Compact Flash) card slot for data storage and peripherals, including Bluetooth CF cards used for wireless communication in the field. The Bluetooth functionality enables cable-free connections to total stations, GNSS receivers, or other compatible devices, which helps reduce the risk of cable damage and increases working flexibility. However, the widely used Socket Mobile Bluetooth CF cards are no longer sold or supported directly as of 2009, so users may need to source legacy cards for this functionality. The system also features robust job file management—files should be stored on the internal CF card (named system CF), as these are protected from deletion during power loss or reboot events.

Field Use and Durability

• The Explorer II is designed for field durability and ease of use, fitting securely in the hand or mounting to a tripod.[lidarmag]

The Carlson Explorer II with SurvCE is best used in land surveying, civil engineering, and construction tasks that require reliable field data collection in tough outdoor environments. This combination excels at collecting precise data from GPS or Total Stations, performing mapping, stakeout, coordinate calculations, and other fieldwork processes critical to survey projects.[precision-geosystems +2]

• Supports many brands (Leica, Topcon, Trimble, Sokkia, etc.).

• Functions:

• Topographic surveys

• Stakeout (points, lines, roads)

• COGO tools (coordinate geometry)

• Data transfer to office CAD software

• GPS & total station control from one interface

3. Typical Uses

• Construction layout (buildings, roads, utilities)

• Boundary and topographic surveying

• As-built mapping

• Utility location with GPS or total station integration

4. Notable Advantages
