I have newly acquired the Raymarine
e7. It is working fine with a Raymarine
DIGITAL radar. It is not necessary to have an HD set. But to work without additional cables
, there the unit must be digital.
Probably one of the nicest features is built-in wifi
server which can connect to both Android and iPad
devices. There are three apps for Android that vary from cheap
to modestly expensive. See https://play.google.com/store/search?q=raymarine&c=apps
The best apps is RayControl which permits full view and control of the e7 and all connected instruments from your Android tablet or iPad
. I have use both and they worked as advertised directly.
The Rayview app is free and simply is a dumb display of the e7 which you can place anywhere within wifi
Also, the Navionics
app on the iPad will sync waypoints, routes etc with the e7. Building routes on the iPad is so simple and then, bing, there they are on the e7.
Therefore, if the screen
of an iPad or Android tablet is sufficient, there is no need to buy a larger MFD.
