Broadcast acoustic release with ONLY broadcast release mode. Best used in shallower/low-medium current waters, especially for nearshore/inshore use. The ARC-2 CANNOT provide status information. The ARC-2 is therefore a more automatic solution at a lower cost.
Service difficulty: Difficult, requires manufacturer.
Battery lifetime: 50 release cycles or one year, whichever comes first. Re-chargable through burn posts.
Release mechanism: Nickel chromium burn wire seated between two titanium burn posts with lever arm.
Expected lifetime: 8-10 years
