    ### BH Navigation Brass Single-Handed 175mm Chart Dividers for Marine Navigation

These BH Navigation single-handed chart dividers combine a solid brass body with stainless steel points. They are British made and measure 175mm, listed in the catalogue as a nominal seven-inch length. The single-handed design is intended for handling the divider opening while working with a chart, making this a traditional tool for measuring and transferring distances. The pointed ends let you set a spacing against an appropriate chart scale and carry that spacing to another part of the chart. The brass body and steel points are the stated construction details to compare when selecting a divider for your navigation kit.

### Choosing and using this product

Choose dividers that you can hold and adjust comfortably at the chart table. Before use, inspect the points and the movement of the legs, then set the opening against the scale appropriate to the chart and the measurement being made. Transfer distances carefully and recheck the spacing if the instrument moves or is put down. For marine chartwork, use the correct chart scale and navigation method rather than treating a fixed divider opening as a universal distance. When stepping a distance along a route, keep track of the number of steps and check the remaining fraction. A divider transfers the spacing you set; it does not make the underlying route choice or chart interpretation for you. Use light, controlled contact so the pointed ends do not unnecessarily mark or damage the chart. Keep the tool secure when the boat is moving, and store it with the points protected and away from loose items that might be damaged. The catalogue’s seven-inch description is a nominal size alongside the specified 175mm length. It should not be used to infer an unlisted opening range, precision rating or additional accessories.
