AT Pro turning off using NEL Attack coil

[ypudding]

used my new Nel attack coil on the AT pro for the first time today. For some strange reason the detector keeps switching itself off (mainly in pro mode) which was really frustrating. Especially as it wouldn't turn straight back on sometimes and I had to wait a minute or so. I need to investigate this further but wondered if anyone could shed any light on this or have had the same experience.

The detector worked fine for the first 2hrs and didn't shut down once. Battery power light was flicking from top bar to second one down so plenty of life in them.

I would say your battery pack is loose if its turning off no its own.

Some have said it overloads the machine when hitting certain targets??? ie large chunks of metal.
