Let's talk dumb though. I took my Equinox 800, equipped with the new 10x5 coil, to a dog park 30 miles away, along with my dog BTW. The dog factors in. I got distracted packing up being the dog was muddy, and left my detector laying in front of the public parking lot, close to a trash can. It was 4 hours later that I discovered my trunk had no 800 and coil. FOUR hours! I ran there immediately with my heart racing, feeling stupid. The first place I chose to look was a failure, but it was my last, and logical place to look, being the last spot before packing up.
It was at the first trash barrel, sorta secluded behind the big pipe used to block vehicles from driving into the park turf.
The feeling of finding that kind of investment still there was numbing. I wouldn't give a single odd to find that gear after 4 total hours. There were 4 vehicles parked neatly near that pipe also.
I suspect the MXT is ok, unless it was in a low spot in the truck bed and was submerged at all. Those machines are surely somewhat water resistant.
