The revolutionary solid state electronic compass is designed around high-tech magnetic and 3D gravity sensors to compensate the compass reading for rolling, pitching and acceleration. Since there are no moving parts and gimbal there is no wearing out, which substantially increases the reliability. The design also increases the resolution and accuracy. The sensor and indicators can be provided with 433MHz wireless data connection between sensor and one or more indicators or laptop. In this case only 12V or 24V has to be connected to the units. This option gives a hassle free installation. Another option is GPS. The combination with indicator ECI2 turns the compass into a navigator. Besides the magnetic heading, true heading, ground course, drift, trip, log, longitude, latitude, time and date can be displayed. Electronic alignment
