I just tested the updated Mx Sport, and am extremely happy with the results! The recovery speed is very good. I was running it against my F75 Ltd, and it could hang with it! I've been through every mode, in ground testing, air testing, and I can't find a thing wrong with It. It's a superb performer and value at this price point and beyond. I could play a song with this thing in 20 tone mode, it's good. I've had coins extremely close together and it will pick them out at a very brisk sweep speed. This update is a real game changer for this unit in my opinion! If you've seen my channel, you know that I've used and reviewed many units. This version is very good. I feel confident that I could hunt with anyone without a worry. I just pulled a large cent out of extreme trash with this unit. I'm very satisfied with the results of the changes Whites has made. Remember that there have been growing pains with units from many manufacturers. Faulty coils, no cam locks, pinpoint bugs. All sorts of issues from different companies. I give Whites a great deal of credit for jumping on this quickly, and fixing it! Top quality company that stands behind their products.
