the Nox recovers so fast if there is a target near iron you will hear the non-ferrous tone

[halfstep]

Tried a test today with the Nox, with the iron post in the tot lots, i put a dime next to the post and swung the Nox, i would get the iron sound of the post but not the dime, kept moving the dime out until it would pick it up, it finally saw the dime at 5"away from the past. This really bothers the Nox with big iron. Used standard settings with park 1 and park 2

When you are around large steel playground equipment, or posts, or concrete with reinforcement rebar/wire like a basketball court, then turn your sensitivity down low. Maybe around 6 and this will allow you to get closer to the objects without setting off your detector. It will still retain adequate depth to find lots of loot.
