T&T: Radar upgrade R70 to R80 for MARPA

[John Esch]

I have a chance to upgrade my Raymarine R70 to R80 radar display.
The major advantages that I can see are:
    1. Larger screen by about 50%
    2. MARPA capability to identify & track up to 10 target
    3. I believe all equipment (radome, Raystar 125 GPS antenna, & cables 
are all compatible.
            Therefore unplug one display and hook up the other.

Any comments on pro's & con's of the R80 will be appreciated.
As always, thanks in advance for your outstanding & sharing expertise.
