Hi,
I was going to get a couple of these at the end of the season for 'knock about work', bringing to the field etc.
Seemed like a handy unit.
Then just recently I checked out a friends model which had been set up with one of these ( can't speak for how he used it - said he had the model stabilised ! ).
Anyway, according to my meter, one wing panel was 0.23* out relative to the other - there was also a twist in one panel which complicated the comparative reading.
So this morning I went on Wixey's website.
To be fair to them they only claim Accuracy at 0.2* and Repeatability at 0.1*.
That is a possible compound error of approaching 0.3*. Even the 0.2* accuracy is not good enough for our purposes imo.
One can of course use a method to improve the accuracy of this but that is a pita.
