- Grand Banks Classic 42
I have roughly 6 yr old Airmar depth sensors on my Grand Banks. My Depth/Temp sensor is a smart B122. When I reach depths of over 100 ft, my screen blanks out even when I slow down to idle. It reads again fine at shallower depths but will not read depths over 100 ft. Sensor range is spec'd at 500+ ft. I cleaned the sensor but that did nothing. An Airmar tech guru says I should try a firmware update but that requires bringing in an instrument professional with a tester. Anyone have a similar experience like mine to give advice? Also, re: in-water sensor removal using the plug. I've never tried this before and I'm a bit timid about trying it myself. Is this easy for a mechanically inclined owner to do?
