| | Transducer installation
I have a 218 DLV Carolina Skiff and I am going to install a 'puck style' in hull transducer. Airmar Model P79 to connect to Garmin 546S.
The instructions say to place the unit in the bilge with a sand bag to hold it firmly in place while motoring over deep water to find the best location for installation.
Then it goes in to the installation detail process of preparing the surface, aligning the flange, filling with propylene glycol, etc....
If I find the best location using the sand bag method as mentioned in the instructions, why can't I just clean the surface and silicon the puck to the hull and call it a day?
Thanks for your help and responses.
