Review on Enhanced Visibility: Raymarine i70s 4-Inch Color Display for Instruments by Nathan Guzman

Beautiful bright screen. Like all new Raymarine equipment, it looks stylish. But this unit, like ALL new Raymarine MFDs, doesn't broadcast as much NMEA PGN as you might think. In particular, this is the temperature of the exhaust gases. Essential to managing the performance and health of a diesel engine. Unfortunately I replaced and upgraded all my electronics only to find this little gem later. Also, no third-party sensors are calibrated, but they don't offer their own version. Like Bennett trimmers. Completely incompatible, you need to buy another MFD so that it stops flashing on the screen. I'm in the process of installing some Maretron hardware to fix this Raymarine error. I would like to warn you that Raymarine does not get along well with others and shows rather than goes. It really shines in places, but when it comes to handling the boat, this new Raymarine and Lighthouse 3 gear lacks key features that true cruisers need to stay on top of their boat's systems.
