Re: fish finder cable ?
If you are referring to transducer cable which is normally part of the transducer, most are not interchangeable. Transducer wise and pin connector wise. There are some that work on a number of the same brand models. Even that info is hard to find. I am not aware of any all inclusive DB, but that would be nice. Some transducer mfgs provide cross-reference to other brands/units, but generally very limited to higher-end models.
