We've all checked our speedometer to see how fast we were going and then checked our GPS to see how fast we were really going. Now the second step is no longer necessary because Livorsi Marine has introduced the Gaffrig Satellite-Guided Analog Speedometer. They're easy to read, and a memory-recall switch lets you view your highest and average speeds.
Installation is easy.
Simply mount and connect the included antenna and mount the gauge in the dash. Your boat has batteries and shore power to keep onboard devices functioning in your absence, and it has alarms to signal that it's in distress. But if the batteries run down, or the shore power is turned off, or no one can hear an alarm, the boat could still sink at the dock. Now Strison Wireless Systems' Dock-Alert 2000 can let you know when this risk exists. Smoke and fume monitoring is optional.
