Well I just pulled the trigger on another Raymarine head unit. This time an e7 unit, I am planning on networking this with my a68. I can't wait to have these 2 units so I can have a dedicated gps unit and sonar. I bought the a68 and going split screen has been a royal pain but now that I have the 2nd one it will make life so much nicer. Of course I don't think the wife is going to see it this way. Better to ask for forgiveness than permission!
