The Scout is a lightweight electric powered quadcopter. The Scout's batteries give it flight times of about twenty minutes, and its stock EO and IR camera payloads can produce real-time video or imagery. ACUASI has used the Aeryon Scout for a diverse set of missions, including salmon nest counting, oil-field infrastructure inspection, marine wildlife counting and monitoring, and thermal mapping of hot springs. Although the Aeryon Scout was once the work-horse UAS for ACUASI, over the years it has been used on fewer and fewer missions, slowly giving way to the Ptarmigan.
