I am thinking about getting it, I guess if it doesnt turn out to be very good, I can always return it.

The GPS gives you coordinates along the way that you can check against your speed to make sure you are at the right spot ?

The Magellan has a vacumn mount I suppose it adheres to the windshield so that it is in range of view. Doesnt seem to be a very good setup. What are the rules to have it mounted in the car.

The screen is about two inches square. How hard is it to read at speed, and do you use a navigator to check your position.

Sorry about the delay to answer your post. I'm in Minnesota on vacation. I saw a Mosquito chasing a duck today. My navigator and Son, held and read the Garmin. We used the course notes and compared them, but mostly used the average speed on the trip computer of the GPS. It reads to the tenth of a second. When you teter between tenths, you know you're really close. Verify your speeds by the odometer and clock, you can get pretty accurate.

Good luck,

I don't really understand the need for
all the high tech gear...GPS...Wheel
transducers...computers...etc. We've gotten times under 0.400 seconds in the last three
races with only a stop watch and a piece
of paper...NO pencil required.In The last race, we beat a Mustang that had a fancy
rally computer with a transducer in the front
left wheel to pick up rotations for speed
and distance measurements! Hint...GPS is
useless in the last mile...not accurate enough!
No matter what method of navigating is used, the bottom line is the drivers ability to hold a constant speed, and to make very small adjustments to speed. I learned that last year at the Gold Rush when I was given the oportunity to drive one leg. Navigating is much easier then driving!!!
Buy one! Great toy and is helpful as long as it gets a good signal ( external antenna mounted outside the car ). The old GPSIII or the newer GPSV are great. Contact GPSCity on the internet for good prices. They both show actual speed, Average speed, Max. speed, distance and moving time.
To GPS or Not to GPS? Good question.
Having never used one in almost 10 years of running the NORC, I don't know for sure. When I NAV'd for my father the first 7 years, we finished in the top 3 in our class 5 times and averaged 95.0003 one year, using nothing but a stop watch. The last three years operator error (running solo, no NAV, Time marker sheet mounted wrong place so could not see it with helmet on, having too much fun just going fast)has gotten me no closer that 1.89 second.

But back to the question.
You can do quite well using just a stop watch, of cource the mile markers are not 1 mile apart (in fact last mile marker before finish line is only about 5100 ft), so you will need some time to get your landmarks calculated out, mile markers to time and so forth.

With a test run using the GPS you can most likely get your lankmarks and time setup done. Then the GPS becomes a valuable asset, both in getting your base setup done and during the run as a reference.

There are a lot of other people who have run the event to get advise from, just have to ask, most will share some planning ideas.

So it boils down to how you want to challenge yourself in running the cource. Both using and not using a GPS has a equal challenge to it. So to me its a toss up as to using it or not.

I plan to maintain the stop watch only operation, but now I have a NAV, so now I can drive and have my NAV do the stop watch, time sheet, speed up, slow down calculations for me. Of cource if we do well it was the Driving and if we do bad it was the NAV (Ha Ha Ha)

"Navigating is easier than driving" ???!!!
In the past several years I've navigated 5 times and drived 4 times. The best I did navigating was about 0.25 seconds error (95 class). Most of the time I was around half a second off. By contrast, the last 4 times I drove, I was under 0.1 seconds every time. My hat is off to the driver/navigator teams who nail their times (D.B. Tanner and Ted Zaleski in particular). I certainly haven't figured out how to do this yet!

Personally, I don't know how to use a GPS while driving -- but then I saw Larry Stock pushing buttons on his GPS. He was as fluent with his GPS as a secretary with a typewriter. I simply rely on accurate measurements and target times, a stopwatch, and my navigator tape!

I will stick by my statement that navigating is easier, at least for me. As the navigator all I do is tell the driver if he is fast or slow at each checkpoint. It is up to the driver to modulate the throttle to change the speed by a miniscule amount.
Of course the driving is a lot more fun. And we do not have the use of cruise control at 135MPH.
