    I see gps speedometer were brought up again you guy that have the Z sprays that have the forerunner 101 on them how do they work i used a garmin last year one thats made for your car and the speedo part is all over the place at 4 to 5 mile range not to good at low speeds i was told they only check every 3 ft i was wondering the forerunner does better at telling the MPH because it is made for walking / biking or you get the same thing
    Thanks Charles Cue

    I use a conventional Bicycle speedometer with a magnet on the wheel. Because of the smaller wheels I don't get a true reading. But I have calculated the actual speed and it works well for me. I am only looking to maintain a constant speed.

    BTW I got that Idea from right here on Lawnsite. Like I posted before a few years back there were a lot of posts about home made Spread N Sprays.

    I have two of the Forerunner 101's and they work great!

    They are very accurate on speed...but not so much on distance. They are close on distance but are usually off about 1-2 ft most of the time!

    Can get them cheap on ebay!

    Here at LT Rich this is almost exactly what we have determined as well, very accurate for speed, but the distance can be a little off. It is still pretty decent ot mark off a perimeter to get square footage.

    When you do use these for a ride-on, be sure you change the Forerunner 101 to biking mode. When we receive ours they are factory set to running mode.

    After reading the posts above and googling the Forerunner 101, I admit my bicycle speedometer it old school. While I have 3 different measuring wheels. I can see one Forerunner 101 replacing them as well as two speedometers. I am sorry I offered bad advice, but glad to learn new technology.

    Which handle mount accessory would you recommend to mount it to the z spray? They have a few to choose from.
