I fly my MA 90% of the time over the dirty lake and in the Bahamas even close enough to see the prop wash on the water. Never turned off any sensor and no issues
I used the Express option and glad I did... my replacement shipped before receiving the repair quote.
Only issue I have now is they want me to pay the difference in the $69 I paid and the repair quote. They told me pilot error is not covered in the refresh program even though it says it is on...
