Wiring a 13" or so flat screen to depth finder.

Hey Guys.

I am a vision challenged individual. I need a bigger screen to see what is going on on my depth finder. I have resolved the power issue with an inverter, I think.
Does anyone have any idea what would be involved in wiring a monitor to the output of the depth finder. I currently have a eagle magna III times about 4. (Several new units as back-ups new in the box.) Have thought of buying a unit that I can also mark GPS on. I have a magellan grey scale and an expensive color magellan unit that I don't use due to the lack of knowledge and abundance of features involved.

Anybody have any ideas.

Thanks

ask mr. cane pole.

You are in deep doodoo. Sell off what you got and get a big screen sonar.

I have vision issues so, I have been toying around with vairous configurations for several years.

There are several options, however, each has its weak points and strong points.

I willl post info later today. Wife beckons me.:o
