Product review (2 stars): Seems like a well built instrument but out of the box ...
Seems like a well built instrument but out of the box the dust cap removal also removed the sensor plastic protective cover. Discovered that the plastic dust cover was stuck to the sensor plastice protive cover and that the threads were stripped causing both covers to come off. Sent it back. I wanted to replace my 15 plus year Dickson instrument (which is still working great) with something newer but it's not this instrument. I'll just keep using my Dickson for another 15 plus years.
