I have an Interphase 20/20 fish finder, depth, temp and speed box from the late '80s/early '90s. *It is connected to a thru hull transducer that I'm having a heck of a time getting a manufacturer or part number off of. *The Interphase box manual says it uses a 200k Hz transducer. *All works fine on the box, but it is very difficult to read the CRT display in the sun. *I'd like to replace the box with a combo GPS, depth, speed, fish unit or just a depth digital read-out unit. *I've combed the Interphase web site, etc. for compatibality info without success (don't have a part number!). *Any experience with wiring up an old ducer to a new unit out there? *Are there Internet resources I'm missing? Any and all help appreciated. Thanks!
