The Model 3078 Series Stretch Scopes are designed to survey areas for gamma radiation while maintaining distance from potentially high radiation fields. These instruments include external GM detectors mounted at the end of a 4.7 m (15.3 ft.) carbon fiber telescoping pole, allowing the detector to reach areas difficult to access with other types of instruments. The Model 3078i versions have an additional internal GM or scintillation detector for monitoring user dose exposure.

The meter body is made of durable, high-impact plastic with splash-resistant construction for outdoor use. The instrument has a large, easy-to-read LCD with a backlight that adjusts to changing ambient light to provide optimum viewing in any conditions. User-adjustable audio levels provide the operator with audible clicks and alarms across all modes of operation. The meter is detachable so it can be used separately from the pole detector.

Each Model 3078 Series instrument has four modes of operation (RATE, MAX, COUNT, and DOSE) selectable using the MODE button. Measurements can be collected in two sets of units (primary and secondary) for all modes of operation by pressing the UNITS button. The external detector can operate in LOW, HIGH, or AUTO range modes by pressing the DET button. With data logging enabled, a simple press of the LOG button will record and time-stamp the current reading. Each instrument can store up to 1000 data points. On the Model 3078i versions, the internal detector runs continuously and reports accumulated dose measurements, which can be viewed at any time by pressing the PRG button.

Display Range	1 µSv/h to 10 Sv/h (0.1 mR/hr to 1000 R/hr)
Range Selection	LOW range (1 µSv/h to 20 mSv/h, or 0.1 mR/hr to 2 R/hr); HIGH range (8 mSv/h to 10 Sv/h, or 0.8 R/hr to 1000 R/hr); or AUTO range across full display range
Display Backlight	Built-in ambient light sensor automatically activates LED backlight unless internal dipswitch is set to continuous-on (will reduce battery life)
