I know this is a personal matter but I am waiting for Garmin tech support to answer. I am wanting to buy a GPS device that is accurate atleast to 2 meters.
I know there are many high tech and high intellectual folks of Freerepublic, so I decided to ask.

If you buy a modern GPS receiver, the accuracy will have nothing at all to do with which one you use. GPS accuracy is a function of the physics involved with satellite positioning and the number of those satellites being tracked by your receiver. The more satellites it receives at once, the more accurate, up to a point. AFAIK, the best you get with GPS is about 15 ft (5 meters) accuracy.

Is this for a rack mount?

My Garmin 182C with charting is usually showing accuracy at 8 feet. Sometimes it is 6 feet, sometimes at 9 ft. This is a 12 channel WAAS mounted unit on a 42 ft sailboat.

Garmin is an excellent manufacturer. If you want the ultimate accuracy and precision you need to go the route of base station and field station. Differential position can get down in the centimeter range.

None are that accurate except differential devices like those used by surveyors, and you are talking $$$. WAAS capable units are the most accurate handheld and dash mount units you can get. The accuracy isn't really determined by the unit, but by the system.

they are actually accurate to inches....but the government has a "wavy" signal so they are not perfect...and you can understand why...
I have a Medillian gold...color screen..and you can buy maps for all over the world..

If accuracy is your thing, buy the smallest models of surveying GPS units with differential capability.
We're talking milimeters, then.
Kinematically (in motion), they are accurate to + or - 4 inches.

$$$ is correct. Surveyors do this, but the casual user would find it hard to justify the expense even if the base station is already in.

For hand held, I use a Magellan explorist 200. Works great and was less than $150.

Sorry, I was mostly Navy. I should have said 19" rack mount.
