> Is this widget capable of judging distance travelled independent > of local currents? > I've rethought my earlier reply about using a GPS receiver: There are actually two "distance" measurements that are not equivalent: 1. there's "True" distance, measured relative to ground or on a map. GPS'es are excellent for this. 2. there's "Muscle" distance, which is just the length of the water you have paddled across. This can only be measured by looking at the water directly below your boat, for instance with a device a previous poster described. Only without current both distances will be equal. On a river with a few miles/h of current, you can paddle a day and get nowhere, or not paddle at all and still cover quite some distance. (wonder why river marathons usually go downstream ? ;-) regards, Kees *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
