Cheers Mark

ok  i did it

min speed was 2 knots so i made it 1 knts

another thing how do i display my max speed while im sailing? i have to wait till i get home and put the card into the computer.

Justin,

You can go to the Trip Meter then to Trip Meter max Speed page. You can also use it as a speedo, if you just select Speed page.

Note before you sail reset all settings in trip meter pages.

Plus before you sail clear the Data logger.

You can also set up your speed genie so you can see your top speed after every run.

Cheers!
