Just noticed it is not the hd one...
Ignorant advertising. The picture is the HDSI transducer but the model name is the Compact SI transducer. Not only that the list of compatible units has models with standard Compact SI transducer and models with standard HDSI transducer.
The price is closer to the Compact SI transducer cost than the HDSI cost.
