How accurate is the speed/distance measurement? I'm trying to decide if I'm going with the Garmin Forerunner 305 or this Nike + iPod sport kit. For me, the most important requirement is truly accurate speed/distance measurement. My speed varies considerably and have never been even slightly satisfied with pedometer style measurements.Assuming the sport kits accelerometer is very high quality, it should be capable of providing all of the same velocity information as the GPS powered Garmin Forerunner, but with the added benefits of playing music, distance/time voice overs and, of course the "power song"... Bottom line, if the sport kit is done right, it has more potential than the Forerunner. How accurate is the speed/distance measurement?

there's also the fact to consider that the Forerunner's about 10 times more expensive

The Nike + iPod Sport Kit (NSK) is not THAT precise. After using it for five months, I can attest that, on a 5 kms track, it will report between 4,8 and 5,6 kms. I'm not yet sure what causes this, but I think it's a function of temperture. It seems the distance is off by 500-600 meters (on the 5 km course) when temperature is around -10 ?C. As another example, today, it was off by about 30 meters, but the temp was -3 ?C. Last fall, with temperatures ranging between +5 and +15 ?C, usually it was short by about 100 meters. A quick calculation gives +- 2% accuracy under those conditions.. As usual, YMMV.. The Nike + iPod Sport Kit (NSK) is not THAT precise.

I've used the first generation Nike SDM unit(which is an accelerometer) with much success over streets, trails, and races. Over a marathon it was within 10 feet over the entire distance. So I plan to check this out, first without purchasing the shoes and just strapping the accelerometer to my shoe. Once calibrated, I expect it to behave the same as my SDM.Once you have a nano it is a pretty inexpensive running tool. I picked up a 1gb nano brand new on craigslist (sf) for $100. I will purchase one tomorrow and try it out over the weekend.

Hello Bruce, I had the Nike+ Sportswatch GPS and needed a HRM to go with it. I just checked the Product Description here on Amazon and found the following: "Polar WearLink+ transmitter Nike+ picks up your heart's signals and transfers that data into the Nike+ system. The soft fabric chest strap seamlessly adapts to your body shape, bringing full freedom of movement to your training. With its hook mechanism, transmitter is just as quick to put on as it is to take off.Transfers heart rate information while swimming with products which support 5kHz transmission** FT1, FT2, FT4, FT7, FT40, FT60, FT80, RS100, RS300X, RS400, RCX5, CS100, CS200, CS300" so I guess it does work with the CS300

Hi Frank, It doesn't use GPS. That is one thing I wish it did. So when you are on the treadmill you just have to swing the arm that the band is on. I have a friend that puts it on his ankle when he walks on his treadmill because he holds on with his arms. He says it is very accurate that way. I swing my arms and in my experience it is very accurate. Hope that helps.One more thing, you can change the mode to logging a workout. That way you get the benefit of a workout and it show your progress that way.

I'm a cyclist only and got the 910XT since the multi-page displays are both large & easily programmable. I mostly use the 910XT for cycling indoors at spin classes. However I have used the foot pod for walking indoors on the track. I have a bad knee and can't run at all. However I understand it works for running indoors also. Outside it uses the GPS - although I don't know how it would measure your stride - but it does work for speed & distance. I hope that helps.

Hello Kim, I have had the Garmin S1 for several weeks now and have enjoyed using it. It has helped my game and gives me all that I need - accurate yardage to the front, center and back of the green. I am about a 17 handicap golfer and I do not need the additional features of the S2 and S3 which provide more information to include distance to hazards on the S3. The S2 is maybe $70 to $80 more than the S1 and the S3 maybe another $100. I need glasses to read the small print and appreciate the S1 with the large display of numbers. I could not effectively use the other models without putting on my reading glasses which I do not want to do while playing golf. I hope that helps - Have fun - Jack Hello Kim, I have had the Garmin S1 for several weeks now and have enjoyed using it.

My watch came with a heart rate monitor (maybe as a bundle package) so I didn't have to pay for that but I do not have the foot pod but I also don't care about the data that the foot pod gives. The heart rate data was important for me to want know. If you are just wanting to track distance data (with the GPS), then you do not need the heart rate monitor either.

Hi, If you have an Ipod Nano you can try the very cheap, in comparison with GPS, Nike+ Sportkit. Once you calibrate it, it is very accurate. All my runs (same route) about 8km only vary on +/- 100m. Hope that helps a little bit.

This pod is completely compatible with Garmin Forerunner 15 as indicated in Garmin's page: https://buy.garmin.com/en-US/US/shop-by-accessories/fitness-sensors/foot-pod/prod15516.htmlAmong many devices, the Forerunner is number 6 on the compatible products list. Enjoy your running!

I use it for the same reasons and after you calibrate the pod, it gives you a fairly accurate reading. I really like that it counts your cadence, it is a very good tool, especially for the treadmill. I hope this helps.

it is a great computer, and does cadence very well. I've had mine all season, this year, and it has performed flawlessly! I would buy the same unit over again, if this one were stolen. I believe it is very accurate (you input your tires actual circumference, for best accuracy) I tested it with my garmin gps, the mph displayed, matched at any speed.

Calibrating does, indeed, help, and it's really easy to do (just follow the on-screen instructions).Out of the box, my kit was about 20% off from reality (on a 10K run, it was only showing 8K traveled). I used the local high school track to calibrate the kit by doing a measured 400m lap around the track, and now I'm within 1.25% of accurate measurement which is good enough for me (it's still showing on the low side). This last weekend's 5 mile race shows up as 4.94 miles on nikeplus.com, but that's good enough for me. Hope this helps you.

I have found mine to be very accurate, although sometimes it will be off usually about a quarter mile for a 10 miles ruen. I think it has more to do with the movement or adjustment of the satelites rather than the watch, since I have noticed on the peaks website that sometimes the course is really off and has me starting out in Lake Erie. There is not really much you can do about it and all brands pretty much use the same gps. If I am running a course for time, I always measure it by my bike or car for better accuracy. I did do a 10 mile race last fall and it showed 10.07 which was very good. Trees and turns or switchbacks can through it off as well.

Did you have any low battery warnings? I always got strange readings when my foot pod battery was getting low (I guess I'm on my 4th sensor, and finally found out you can return them for replacement if it doesn't last a year).I also found that I needed to calibrate mine for the stride length/speed I was running. When I'm doing marathon training or running with friends I apparently take shorter strides than when I race a 10K. Last year I had a 10k register as 9.3K so the next time I calibrated it (vs my Forerunner 301 GPS) again during a .25 mile warmup at 10k pace. Second 10K I got 10.2K so it was better.

Yes Yes and Yes. I have checked with other heart rate monitors for sport use and after averaging and allowing scientific deduction I am sure ,this is most accurate continous heart rate monitor.
1782953
I thought so. The mph it's always displayed and the various modes are in smaller font. If your working on keeping a pace or working up to one, this gives you an accurate measure. If you don't need cadence there are cheaper models. For another 10 bucks this is a good feature and this is one of the cheapest computers with cadence. Add solid product too.

As long as you're outside and the watch can receive the GPS signal, you can run, walk or simply play soccer and distance will be tracked. This particular model "gets" GPS signal always in less 30 seconds which is considered pretty fast, however I would be slightly concerned about the ball hitting the watch during the game. I hope this answers your question.
