what does this do?

It's a fluxgate compass.

You have an autopilot and that is the heading sensor for it.

RULE #1

Keep ALL metal at least 18" away from it. Like toolboxes and stuff. Otherwise you'll engage the autopilot and the boat will turn dead left...or right...but it won't go straight.
 
Whooaa lol ok now could that be the bad sensor thats giving my factory gps the wrong position readings? Its mounted right next to rod holders that were empty up until about an hour ago.. I never actually had a chance to cruise long enough to engage the auto pilot and check to see if the heading was accurate. I know it works but just never thought to check the degrees up agains something I know is working
 
Shows how much I know, I was leaning towards some kind of high water bilge alarm but if that much water was in that comparment I think I would be pretty much screwed already and being a raytheon product through me off that assumption. Thanks

Not sure that would effect your GPS. Chartplotter/GPS works off the antenna on your arch. This thing is for the autopilot, which is tied to your GPS, but like Rick said, it's gonna make your AP take you places you want to go.
 
The heading sensor can effect what the char plotter shows. On mine a loose wire made the chart plotter show the stern of the boat moving in the direction we were going. The little boat icon was going backwards!

These things are a piece of ****e. You may need to re calibrate to get it to work correctly.

ok here is we're my mind is at. I understand what everything does and I understand what everything is. Now some quick info on my equipment. All factory from 98. Radar with dome. (Old school green display) ray auto pilot, ray GPS. Gives coordinates only. And tri data.
all other equipment was added on like garmine 182c and Lawrence depth/fish fifinder

now I understand (well atleast a little) on how to operate everything as stand alone systems, but using them together as they are designed to be used, I'm completely lost... I've read through all the manuals and have a little understanding but yet still lost.

I know it's a lot of typing but can anybody explain how to use or should I just wait till next year when I upgrade to more modern electronics?

now another note as I posted a couple weeks ago. My gps that gives me my coordinates is off about a mile and at startup it reads back sensor. Now with that senor(what sensor) being ng does that throw everything off?even what my auto pilot Heading is reading?

again this is all very new to me please excuse myth inexperience and explain in terms of dummies. Thanks for the help
 
If your existing GPS is an RN300 that could be your problem. Mine, like many others started intermittently losing its FIX altogether. I left it in the dash, but replaced the "puck" GPS antenna on the arch with a new RayStar125 GPS Receiver. It looks like the original antenna, but it actually houses the GPS hardware within itself. It needs to be wired to a 12vt power source and into your SeaTalk network to work on your plotter and in my case, the VHF radio. It's worked flawlessly ever since.
 
All metal means even aluminum cans of beverages of your choice.... metals too close to kneading sensors - auto pilot can make your boat run in circles... Trust me...
