If your Raymarine Monitor shows no depth reading or has lost bottom lock, check the transducer location to ensure it's installed correctly. Also, verify the transducer angle, adjusting if it's too great. If the transducer has a kick-up mechanism, ensure it hasn't kicked up. Check the power supply voltage under load, and inspect the transducer for damage or fouling.
