So, I am contemplating an upgrade and have been eyeballing those multi-function units, you know the ones that have ChartPlotter/Depth Sounder/Radar/Sirrius Satelite etc. etc. The main impetus is that my little SeaEagle fishinder unit started malfunctioning on me and I was loathe to just replace it when there are so many other options out there. In the end I just bought some time by replacing the transducer and cable, the female end of the connector was badly deteriorated and caused the problem, but now that it is replaced it works again. It was not too expensive a fix $129.00 so if I use it just this season I am ok with it. It was trying to decide what to do to fix it that got me considering other options. I have a little Garmin handheld GPS Map 76cs (bluecharts) for charting and it is already outdated. I just got my Uniden 540 with extra Wham remote last year and before that I got the RayMarine ST4000 MKII+ wheel pilot. I can save the 76cs for back-up and then plan for the big upgrade. The obvious one that comes to mind is the Raymarine C70 Multifunction unit because it includes Seatalk networking capability to drive my wheel pilot, plus it has Chartplotter (Navionics), Sonar/sounder optional Radome for future radar and Sirrius Satelite weather availability and so on. It is the entry level multifunction unit but seems to have it all at a reasonable price. the display will be a bit humongous sitting on my Macgregor 26M pedestal but at least I have everything available right there at the helm and it does have NMEA compatability for the DSC Uniden 540 MMSI connection so it is starting to look attractive. Does anyone have any experience with this model or any opinions an any brand that is multifunctional and what is the consensus for multifunctionality? Is it the way of the future for boating? I will check out all the systems at next seasons boat shows since it will be next season before I jump in over my head but I would like to hear others experiences with the multifunction units.I provided a link to the RayMarine Unit.
