From the Manufacturer’s website:

The Model 26-1 Integrated Frisker is designed to simplify the process of detecting radioactive contamination on people and objects. Unlike other meter and detector combinations that require two-handed operation, this instrument combines the meter electronics and detector in a single, easy-to-use tool. Its design incorporates a 15.51 cm2 (2.4 in2) GM pancake detector, an easy-to-read LCD screen, an ergonomic handle, and a simple three-button interface to allow one-handed operation.

Three modes of operation are available — RATE, MAX, and COUNT — which can be selected by pressing the MODE button. RATE mode displays the current count, exposure, or activity rate. MAX mode captures the highest count, exposure, or activity rate detected; this is useful for finding a peak rate or for frisking when the display is not visible. COUNT mode allows the operator to perform a survey for a preset amount of time; depending on the chosen units, the count result can be a scaler count, a time-averaged rate, a time-averaged exposure or dose rate, or an integrated exposure or dose. Measurements can be displayed in units of cps, cpm, dpm, Bq, mR/h, or μSv/h. The user can switch between two sets of chosen units (primary and secondary) for RATE and MAX modes by pressing the UNITS button.

Other features include an auto-ranging and backlit LCD screen, “click” audio (which can be silenced), and user-settable count rate and scaler alarms. The instrument body is made of high impact plastic and water-resistant construction allows the instrument to be used outdoors. A wrist strap and lanyard are included for keeping the instrument close and secure. The instrument is powered by two alkaline AA batteries with a battery life up to 1000 hours.
