Dominique,

If the speed reads 0.00 then the hull transmitter is working and you probably do not have a problem with the depth transducer. The depth displays -.-- when out of the water, so unless you can force something against the depth transducer to simulate a water mass for a return, the display will not register anything. Here is a photo taken on Rhapsody a couple years back with the boat on the hard. Note the depth display at the top.
