Re: Christmas GPS $600.00 Budget

O.K so my new Garmin GPSmap 50 in the mail today. The cabling looks to be straightforward. I have to find out what to hook all the other stuff to.
The GPS and the ST4000 are all that I really want well, I will want the depth and temp transducer as well.
Anybody know which of 3 choices will be better. Thru hull bronze I have a hole in the boat for that now that has a plug in it. It was for the paddle wheel water speed. Or the outer choices a transom mount or a in hull puck?
I will have to take this slow.
all greek to me.
Thanks for your help.

Re: Christmas GPS $600.00 Budget

After a lot of research and asking a a lot of questions.
I came up with the Garmin echoMAP50s.
It has a lot of stuff I need and I can upgrade it later with no problem. The biggest concern was that it would send the information to my Raymarine st4000 autohelm. I need to be able to steer the boat with the gps some of the time. It has a photo map chip that will help create routes using google earth maps. What that means is that is I put a way point on one side of an Island and the second way-point on the other side of the same island it will create a rout around the island not threw it. I will have to load some basic information into the unit first. Draft, height, length etc.
Not sure if it will read my depth/ temp thru-hull transducer I own now. All of my instruments are rarmarine st50 0183 seatalk. it would be great to link in all or at least the the autohelm st4000 and depth into the new echo50s.

I want to be confident of my off-shore training. I needed a good unit to help with that. I now have a GPS 76 handheld that does not have maps. I think I will upgrade that unit to a hand held that does have maps. and this new unit. I have been studying charting as well. Thanks for all the help guys.
As I move forward in this most excellent journey I have you to thank for much of my advancement in the process.

NMEA 2000 is even easier than NMEA 0183 in my experience. It is a lot easier to expand the network.

At $600 you are just getting to the price point where NMEA integration is an option. Check units and manuals carefully if you want that feature.

I do find the fish finder view useful when anchoring. It gives you a pretty good understanding of bottom conditions that is difficult to get with just a depth finder number.

Depth transducers are often compatible between brands if you can figure out the wiring. Airmar makes the transducers for everyone and documents the wiring for almost all brands. A 200khz transducer is the most common.

NMEA0183 stuff is usually pretty easy to get to talk to other NMEA0183 stuff, most of the time just wire it up and you're off, default speeds are normally 4800 for everything aside from AIS which runs at 38400. I haven't played with NMEA2000 stuff but I think it's similarly straightforward.

How old is your 4000? if it is more than 4 years old, it will be NMEA 0183. Check your Autohelm manual to be sure.

Re: Christmas GPS $600.00 Budget

I found this researching the web for answers.

Connect your Navman NMEA Out (+) to the Autohelm NMEA In (+). Connect the NMEA Out (-) on the GPS to the electrical (-) of the autopilot, (NOT the NMEA (-)). Configure your GPS to talk NMEA 183. Set a course on your GPS, Sail that course. Hit (Track) on the Autopilot. Watch out for other boats. Good luck Steve Alchemist #909 p.s. The Raynav ST-4000 manual tells you all of this. You may need to cousult the Navman manual for the colors of the wires. It will be fun finding the right size terminals to connect the

Is this corect information?

Is there differnent versions of 0183? like veirsions 3 and V3.01?

If the Autohelm ST4000 is Nema 2000 it should, but I am not sure. It can get complicated getting the different standards talking and can sometimes work, sometimes not.

Re: Christmas GPS $600.00 Budget
