I can't agree to any of this. Personally, I HATED my MXT until I was able to spend at least a good, solid month getting to know it. The Sport has an infinitely more tweakable interface than the MXT and can be tuned to many different situations.
Out of the box the MXSport is configured for a new user in mind - It's turn on and go and assumes ideal ground conditions.
I know it was mentioned here, but someone suggests running it in 2 tone mode, VCO off, Prospecting. Sounds logical. 20 tones would not only drive me nuts from an audio standpoint, but for any mobile microprocessor to 'think' fast enough to produce 20 distinct tones and assess a metals conductivity, etc. would be challenging.
I'm sure White's is very aware that in order for their new baby to succeed in now fiercely competitive market, it has to perform at least as well as their main competitors.
One thing I will say is that I hope to see a much larger selection of coils. I don't like that big ol' 10" standard DD. When the MXSport was announced, I assumed it'd work with the existing White's and aftermarket coils as it's the same frequency, etc. Maybe they're working on a waterproof adapter? Time will tell.
