Radar vrs. GPS & radar

I''m looking at equiping a new boat with chartplotting GPS and considering radar as well. Both my budget and console space are limited. Any comments or experience on combination units like the Raymarine SL70CRC I assume I can operate it as just a chartplotter when that''s all I need, and switch the radar on and off independently. What do I sacrifice without a stand alone GPS?

Check out this link to my pedestal upgrade web page. I went with an SL72 and a Garmin GPS Map 176. I like having two seperate units in case one should die. The Garmin also runs on AA batteries if needed and the Blue Charts i find much better than the C-Map or Navionics charts...Here is the link just copy and paste it into your address bar.....

I bought the Raymarine SL72RC+ radar/chartplotter last year and am quite pleased. The cost was about $2K with the GPS sensor (I''ve forgotten the model number). You can use as a radar, a chartplotter, or split the screen and see both radar and chart images at the same time (great for figuring out what''s a buoy and what''s another boat in the fog. The color units are about $1K more, and I didn''t feel it was worth it, although I must admit the legibility is probably the worst part of the unit I have (b&w). I think the color units allow you to superimpose the chart on the radar image in a different color.

The Raymarine unit will always operate as just a chartplotter, you can even disconnect the radome and use it that way. The radar does switch off and on independently.

I guess what you sacrifice is the ability to see both radar and chart images at the same time, full screen. But, I''m not sure you''ll be able to have both displays cover the exact same area unless you go with two Raymarine units (HSB, more $). Perhaps Furuno or someone else offers. The real advantage of an integrated radar and chartplotter is having the range and orientation of both be exactly the same so you can easily match up what you see on the radar with what''s on the chart.
