Gps-speedsurfing

Hello gents,

I couldn't find it on the site but has the Garmin Foretrex 301/401 been approved for use by Gps-speedsurf?  Also unlike the previous 101s/201s, the 301s/401s can log every 1 second so I'm going to assume it would be wise to set it to record every 1second?  Or would two still be the better choice?  

Thanks!

-Kevin
