Depth display flashing

tpaw,

Typically, the master for any specific type of data will hold its value longer than repeating devices. In this case, the i70 is acting the depth data master, while the p70 and e95 MFD are repeaters of depth data. Whether flashing or dashed, both are indicating that the Airmar smart transducer has lost contact with the bottom. While instrument depth transducers are generally designed to primarily support operation in relatively shallow water, the depth range reported should be within the specified operating range of Airmar's DST800 (Depth/Speed/Temp) smart transducer. Should such issues regularly occur when operating within the depth range which you have specified, then it would be recommended that transducer and hull be inspected for marine growth and cleaned of any such growth. Should the problem persist thereafter and the DST800 not report depth when operating in the depth range reported and not being propelled by sail or power, then it would be recommended that the transducer be replaced.
