Item # POL0046


Tired of going out for a run and coming back without knowing how far or fast or hard you went? Get answers to all those questions and more with the Polar RS400sd Heart Rate Monitor. This heart rate monitor comes with Polar's s1 foot pod, which interacts with your RS400sd watch to give you accurate speed and distance information. The RS400sd also tracks your maximum, average, and target heart rate information, so you know when to pick up the pace or chill out for a few miles. Polar's OwnCal feature counts the number of calories you burn during your workout, so you can either indulge in that hot fudge Sunday or grab a banana for desert. Polar also gave the RS400sd Monitor its OwnCode, so it won't interfere with anyone else's heart rate monitor on the trail or at the gym. Hook this heart rate monitor watch up to your PC after a workout and analyze your training data.

works for what i use it for!

i bought this to really isolate my calorie expenditure when doing p90x2/running so i can finish losing the weight i have, and it really works well. even though i did buy it mainly for the calorie counter, i use pretty much every feature on it at least once a week because, aside from losing weight, im trying to train for a 5k/10k/half marathon/marathon (havent decided what i want to do yet :P) and the sport zones really help me pace myself so i dont over do it and i train the right way to build myself up to holding a decently fast pace for long term. also the foot pod was surprisingly accurate for not being calculated with true distance so right out of the gate you know how far you run. along with the software and polarpersonaltrainer.com you can really break down each workout and see what works, what you did, and when to schedule recovery days... buy this!

Hi There:Does this unit have GPS with it?...

Hi There:Does this unit have GPS with it? I have a friend who while jogging gets a chime to let her know her miles and in turn pace. Does this watch allow me to do that. Thanx. G Fonseca

I'd believe not, if you look at http://www.polarusa.com/us-en/products/gps this model is not listed as a GPS unit.
