I use polar rs800 with gps and also a m400, since firmware updates the GPS and heart rate accuracy is very good, if the correct sport profile are used and gps is not used in power saving mode then its very accurate now

I have used polar v800 and m400 and not a great deal of diference between the 2 other than the v800 is £200 more expensive, v800 has record rate and few minor extras but too be honest m400 is more than enough for referees
