I have a Humminbird 597 ci hd on the transom and have knocked off the transducer three times. I took the broken transducer and sat it inside the hull and it seemed to be reading fine. Not quite as sensitive but pretty good. Can you put the transducer inside an aluminum hull, I have heard different things about this. Does it have to be submerged in water inside the hull? Does the 200khz or the 83khz work better if it's in the hull? If not are there any recommendations on how to protect my transducer bc this is getting expensive. Also the break away feature on the bracket does not work very well it breaks away on a strong wave. Any advice is much appreciated.
