    I noticed on the new Z-Sprays they have Garmin GPS for speed.

    Anyone know the accuracy of this little unit? It is called a Garmin Forerunner 101.

    I looked on the web and you can get the exact GPS unit for about $70-80.

    You can track your time on each lawn from start to finish, speed and check and distance etc.

    Is anyone thinking of adding this to their ride-on unit?

    This may sound stupid.....but I was even wondering about on larger properties about using it for estimating lawns? You can wear it on your wrist also. Just wondering about this as it sucks to push a wheel over larger acreages that are all cut up.

    I don't know about that unit but I have a garmin in my truck and I trust it pretty well, because it is down by satellite, my truck has about a 3mph difference.

    Every GPS I've ever used or owned was right on for speed. Your truck may be off by the 3mph.

    I may have to look one of those up on eBay... Sounds like a pretty cool little gadget.

    I talked to Andy at LT Rich about it an he said it is very accurate. According to him you can take one step and see it change 3ft.

    I have a Garmin Legend mounted on my Z. It will measure area but I believe it is the only model that will. It is very accurate down to as low as 5K (thats as low as I've checked it).

    Thanks Guys! I will probably just get a Garmin!


    Funny you ask!

    I have a light bar (guidance system) on my big sprayer...and it works great!

    I stopped in yesterday and talked to my Case dealer and I could run a lightbar on my new spreader as it has variable widths. The only problem is that its accuracy is about 6 inches (which is good on a 60 ft boom, but not a 11-18 ft swath).

    If you go to RTK then it you can get within an inch...but that is big money.

    Also this system is a little "bulky" on a ride on...but I am definilty going to keep my eye on it!

    The older units are down to about $1800, which is money well spent when you do a lot of larger properties.

    You can't believe how a unit like this takes the "fatigue" out of the job. You just sit back and drive straight!

    I think I am going to go with the Garmin for now, just for speed!

    I have used a GPS unit to keep track of speed with my larger spray units for several years. I have a Magellan. It will also keep track of your bearing so it could eliminate the need for a foamer. My GPS uses batteries quickly. I have a battery power supply. I also use it to check the speed of my Permagreens when I calibrate them.
