Weems and Plath 10-Point Dividers may appear an extraordinary navigation tool to look at but they perform extremely well and you will soon accept them as a very valuable precision tool element of your sea-going navigation equipment.

Weems and Plath 10-Point Dividers consist of 6-inch equal-spacing dividers manufactured from the highest quality stainless steel.

The eleven numbered points enable you to make an easy conversion of distances.

Weems and Plath 10-Point Dividers are also an excellent navigation device for when you are interpolating Loran, which involves the use of a chart overprinted with a Loran time delay (TD) lattice consisting of hyperbolic TD lines spaced at convenient intervals. The navigator plots the displayed TD’s by interpolating between the lattice lines printed on the chart, manually plots the fix where they intersect and then determines latitude and longitude.

Weems and Plath 10-Point Dividers are also very useful for plotting and calculating using the decimal system.
