This simple to use identification tool shows the actual view of maritime buoyage systems with corresponding chart symbols. It describes bridge lighting and Intracoastal Waterway markings. ROADrule® takes a large amount of complex information and makes it easy to understand and quick to refer to. Whether in a classroom or at the helm, critical decisions can be made quickly and with confidence with the aide of ROADrule®. 
The Hand Bearing Compass can be used in two different ways. To take the bearing of a point, the compass is held near the eye and read down the line of sight. A stable bearing appears in the prism in perfect focus day or night. For quick reference, a heading can be determined by looking straight down at the compass and reading the degree shown with the magnifying lens. The contrasting black and red numbers on the compass card make it quick, clear, and easy to read. The compass features a liquid-dampened card with photo luminescent night lighting that quickly charges by placing the compass momentarily under bright light. No batteries are required. A colorful, sturdy, rubber housing protects the compass. It also includes an integral lanyard, which serves as a convenient neck or wrist strap. The compass has a lifetime warranty, is factory certified, and is accurate to within 1 degree

Chartkit Plotter  

 Chartkit Plotter

 
 This portable navigation system is designed for accurate navigating with any chart, chartkit, or chartbook. The plotter is made of solid wood and an integrated adjustable parallel arm fitted with a moveable compass rose. This permits the direct plotting of magnetic compass courses and firmly supports chart work whether in the cockpit, on deck, or below. Plot a course to a given point by locking the rule at a given bearing. By moving the rule so that the point is on an edge, you quickly determine the correct line of position on a chart for that bearing. A see-through acrylic sheet overlays and protects the chart as you plot and allows for notations using a dry erase marker (included). A tough custom nylon carrying case is included. Dims: 22-5/8" x 20-3/16".
