The MPV II is the toughest ice buoy lantern ever produced, boasting a robust bronze alloy body and a thick molded polycarbonate lens that can withstand the crushing pressures of ice and prolonged submersion. It serves as a modern replacement for the renowned MPV LED, with completely re-designed optics. The MPV II‘s reduced power consumption doubles the battery replacement cycle, while its tricolor functionality minimizes required stock by half. Maintenance and monitoring are enhanced with Bluetooth control and new remote monitoring technology, as well as remarkably improved lantern positioning accuracy.
