ST30 wind instrument

[catalac08]

never had a wind instrument or felt need for one but swmbo insists this would be a good idea so she can exercise her strong wind veto more accuarately/often!
not familiar with Autohelm st30 (appreciate a dated model but needs to be cheap & cheerful) but any views on these would be welcome and does it show wind speed and direction?

better still, could you calibrate it to show 5 knots less than there is ...so SWMBO can use her veto ... but not till you've had a good sail! /forums/images/graemlins/laugh.gif

what an idea -can these be calibrated?

Had ST30 on the last boat. Only grouse was the night lighting - useless, so I fitted a red navlight in the cockpit to shine on them.....they wanted £30 per unit to upgrade the lighting...... Otherwise OK. Does your SWMBO understand true and apparent wind? you can toggle between them to always subtract the difference if you want.
