Collecting Depth Data

python should easily get rid of any odd measurements so fingers crossed, this might just work.....

That's great! Did you check if the readings are accurate? And did you test what is the minimum distance you can measure?

Distance seems quite close with just a knotted rope as a measuring device... didn't pay much attention to minimum depth, won't really be of much interest on a sailing boat, be aground before you get that shallow.. 

Dinghy test next, still have a handheld gauge to check the readings, but seems hopeful that it might spit out something useful, all I want to know is a rough guide of the uncharted anchorage or river.
