I was installing my new Garmin GT50m-tm transducer but hadn't mounted it yet and while my back was turned my lovely little 3 year old daughter decided to play with it and managed to drop it around 2 ft onto hard pavers. Externally it looks fine but I imagine that the internals of these things are probably quite sensitive. I won't be able to get the boat in the water for at least another week so I'm fretting on what kind of damage may have been done. So I just need someone to tell me it's all going to be ok and that these things are indestructible.......
