I'm pretty sure most of the Chartplotters on the market today can display an NTSC image in direct sunlight using cheap RCA cables. However, I would not buy a Swiss Army Knife and only use the cork screw.
The screens used are made by only a couple manufacturers, and could possibly be bought in very small numbers, but that's where the problem arises. The total market for these screens outside the chartplotter segment is virtually nil. Cars and RVs don't need them. Airplanes do and some go there. So anyone who wants to sell them has to build his own cases and pay for certification to one of the standards. He may be able to sell a hundred. That's too small a number to get the price down. For the moment, we are SOL.
There is a glimmer on the horizon: LED TVs. The idea of a TV on the beach might find a market big enough for production economies. LEDs offer a higher contrast ratio and brighter screens.
Here's an alternative: replace those gages with NMEA 2000 transducers. Then you can easily read them on the newer N2K chartplotters.
