Last 3 hunts...Coin count low, frustration level high

The last two weekends now have been a total bust for me. Starting on Sat. the 13th I had some things to do in the morning so no hunting and most public spaces get crowded early here but around 3pm I decided to try and find some open space, my third stop was an empty ball field, I get geared up and by the time I could find 3 copper pennies the cars started to pour in the parking lot. Oh well I think time to head home and get a good hunt in on Sun. I ended up forgetting to put my Equinox away and left it in my car, temps were in the mid 30s overnite and when I get to the spot I'm going to hunt just before dawn about 10 or 12 miles from home the Nox starts going bonkers, I did everything I could think of to get it to stop, reconnected the coil wire, noise cancel, factory reset 3 times nothing worked. Later that afternoon when the machine and outside temps were nice and warm I tried it on my front lawn, worked perfectly so I figured it must be super sensitive to the temperature. Well this Sat. was no different, chores to do so no morning hunt,I went out again for a quick afternoon hunt to a small patch of woods behind an elementary school a few miles from home, Equinox was working well but on my third target I had a bee buzzing my pointer, I flipped over an inch of topsoil saw the rusty beer cap I was digging and noticed another bee was buzzing my detector, in the next second or two I had two of them on my shirt and quickly got up and ran a few yards uphill. While brushing off the ones on my shirt another one stung me on my side just above my belt, well that had me running further uphill, when I stopped and looked back at where my gear was (now about 50 yards away) I couldn't see the control box on my detector it just looked like a big blurry spot, hundreds of bees swarming my gear I had to wait there for over an hour before they calmed down enough to attempt retrieving my stuff.... SCARY! Well today I was able to get out just before dawn again and after about 15 mins. of running fine the Nox went bonkers again, same result, couldn't get it working again. Sorry for the long rant, hope it made you feel a little better about your weekend hunt.
