Using the most current technology and design, American Marine introduced PINPOINTTM Monitors, which have become the most respected line of digital instruments in the aquaculture business. American Marine was the first to introduce a 2 Year Warranty on each and every PINPOINTTM Monitor. For every purpose, from a goldfish bowl to a salmon hatchery, PINPOINTTM Monitors are called into duty every day because of their rugged design, precise readings and reasonable cost. Achieving the goal of "unique technology at reasonable prices," American Marine has sold PINPOINTTM Monitors on every continent. Each monitor is powered by a standard 9 volt battery that is available world-wide.
