Moulded in black PVC with a holding handle to locate in position on the map. All models have a milled internal groove to accept any of the Don Barrow Graticule Baseplates. The 'standard B01 supply' 1:50,000 Baseplate simply clips into the lower groove, to provide a printed Graticule which enables you to either plot Map References or measure distances on the map, see below for all other Scales and LED Options. All Pro-models are fitted with a Superior Quality 113mm dia x 1.5 +/- magnification (50+/-% larger) Crystal Glass Plano Convex Lens. The various models have different switching and bulb fitments.
For replacement Bulb, you now have a choice of either 5 Watt Soft White LED or 5 Watt Red LED Bulb or the universally available cheap to replace 5 Watt Festoon Bulb, all available from my DB Spares page.
