Default Furuno radar help

When using my furuno radar or any radar what does the h up symbol mean . I'm having trouble figuring out what side of the boat potential obstacles are on . I'm not sure if it's like a plotter on north up mode where if your heading south your going towards the bottom of the screen . Shouldnt the radar always give you an image in the way your heading ?

H UP would mean Heads up. That means what you are seeing at the top center of the screen is what is in front of the boat and will stay that way as the boat changes course.

bwilly,

You said "Shouldn't the radar always give you an image in the way your heading?" The answer to that is yes, on a stand-alone radar. If it is a radar overlaying a chart, that might not be the case. If you have a stand-alone radar and it is 180-degrees out, then you need to make some changes in the set-up of the radar.

Probably the best thing to do is look in the manual for how to correct that. If you don't have the manual, I would either contact Furuno or maybe even post this question on their forum. They have people answering questions there that could probably help you. Here's the link: http://www.furunousa.com/Support/Forum.aspx

Hope this helps!

Most radar screens that are not chart overlayed would be oriented toward "heading up". Settings sometimes offer True or Magnetic North up. For navigation purposes, I personally find heading up the way to go....easier to process your next actions.

I find overlaying radar on the GPS chart as THE Way to Go. That normally requires a heading sensor to ensure that the radar picture is properly aligned with the chart no matter how you are heading or turning.
