This is a 2-layer LCD model with a register ring and a triple sensor. Practical specifications are achieved by combining a two-layer liquid crystal display that can display multiple pieces of information at the same time and a register ring that simply displays orientation using a rotating mechanism. In addition to bearing, barometric pressure/altitude, and temperature measurement functions, it is equipped with tough solar. In addition, measurement buttons for direction, barometric pressure/altitude, and temperature are arranged independently. The large button allows one-push operation even when wearing gloves. Furthermore, the button guard, which wraps the outer circumference of the button in a resin material, prevents malfunctions during measurement. A resin band with large screws is used at the joint between the case and the band to improve the strength of the connection. The register ring is knurled to improve the texture and create a sense of functionality and precision as outdoor gear.
