Default Lowrance Radar

I have a lowrance 113hd unit as was wondering if anyone has any thoughts on hooking to a lowrance radar dome? It is supposed to be able to overlay the radar on the gps map. I was wondering if anyone was running this setup? Good? Bad? Thanks for any input Joe.

I was also considering adding a Lowrance dome. Probably the 2kw as I only need it for object/boat avoidance while running at night and fog.

I just installed this set up – LCX 113HD - lra 2000 and kvz 1000. I would strongly recommend adding a digital compass so you can lay the radar picture on top of the map. Makes it easier to read the picture. Works great, no issues. I would recommend to go with lra 2000 and not the lower end models. This is not about the max rang, which is a bit theoretical any how. Ranges depends of the antennas height, the targets height, target radar reflecting area, etc. Most people can not se 36 nm – but higher effect gives a clearer picture at short range, easier to pick up targets that do not give good reflection (like a small glass fiber boat), better resolution due to a more narrow horizontal beam, more adjustment levels of rain and wave clutter rejection. To some extent you could compare it with a flash light – stronger light makes it easier to pick up small details at short range. The LRA 200 is just a better and more advanced radar. And the price difference is minimal. Regarding the pictures posted at Lowrance web page www.lowrance.com/Products/Marine/Lowrance-Radar/ - they are not right. The LRA 2000 looks like the lra 2400hd. The picture under the lra 2000 is a picture of the old lra 1000/1500.

How much does the digital compass run? Is it networked into the GPS?

I payed $350 for the kvh1000. It provides heading data that is used by the gps. Lowrance radar must have a heading sonsor installed or the chart overlay will not work. The kvh is nmea 0183 and very easy to hook up.
I am thinking about doing this as well with my LCX 26C HD. Both the RADAR and the heading sensor output via NMEA0183, so how did you wire yours? Simply sire them together, or did you use a concentrator / buffer?

Bought all my stuff from www.starmarinedepot.com that have pretty good prices. I paid only 245$ for the kvh Azimuth 1000 http://www.starmarinedepot.com/KVH+Azimuth+1000.html

You nee a NMEA connection, LCX 112 and 113 has two, but one is used for the radar leaving you one. You can connect more than one listeners to a speeker, but not more than one speaker to each listener. I have connected both the Smartcraft Gauges and the VHF (for DCS) to one NMEA output, but only the compass to the NMEA input. It is easy to do the connections; I used the connectors that came with the radar.

I think all the radar models need a heading sensor to do a radar overlay on the map. You need something that tells you in which the direction the radar is looking. The GPS can only give you direction of your movement. When you connect the compass to a Lowrance plotter the arrow shoving your position turns read/longer and basically points the same way as the bow of the boat even if you are drifting or backing.
