I managed to get one of the first MX Sports in Utah. After a few days hunting I noticed it would "smear" over adjacent targets. I sent it back for a firmware update, got it back within 10 days, and then used it for almost 200 days before I dropped it and broke the stand. Sent it back to White's and got a new one back in a week! No questions asked. I’ve got to compliment White’s on their customer service. It is the best service of any manufacturer of anything that I’ve ever dealt with. Absolutely Superior!
I've used the MX Sport in rain, snow, heat, mud, dust and shallow water for roughly 10,000 coins ($600), a handful of silver and wheaties, a dozen+ silver jewelry and a .9999 gold ring, all with the 10" coil. I prefer it to my 'old' MXT All Pro, even with the 13" detech coil. The sounds are better, easily discernable, depth and separation are excellent, though ID at depth is sometimes sketchy. The multiple programs and options make it a remarkable machine, especially at the price point. Once you take the time to figure out what the MX Sport is telling you, your finds totals will increase in a variety of environments.
I'm an inland hunter of parks, totlots, schools, bus stops, curbstrips and very few permissions. I'd like to do more, but there is only so much time in life. I have the 7" coil on the way, and have ordered the 13" from my local dealer. I can barely wait until the ground thaws enough to use them.
The MX Sport is a much maligned monster of a detector that will show it's true value as more people use it.
Keep on swinging. GL & HH.
