So, I have had the 800 for 4 days now and only used it for about 3 hrs total. This morning, I went out for my first prolonged use and decided to deviate from the default settings. I went about setting ground balance in both park 1,2 and field 1,2 profiles using Auto Ground Balance. Park 1 and Field 1 worked as expected but immediately after releasing the accept button in Park 2 and Field 2, the display flashed Cd and the unit powered off. During the next two hours, the unit displayed Cd and shutdown four more times while in pinpoint mode.
The manual states this is a coil disconnect error code and to check the connector, cable, and coil for damage but all appear fine. I guess I will be calling MineLab to see what they say. Has anyone else experienced this?
