Great info, thanks for sharing! I now see why you are successful in chasing the weight, you squeeze every advantage out of your machine that it is capable of producing by thoroughly learning and experimenting with the settings. Most of us never reach this level of expertise with our detectors, the majority of us are "Turn and Go" junkies who never really realise what we are missing.
Many of us are in the same situation with the GPX 5000 and now with the introduction of the ZED are thirsting for some miracle settings that will give us some more depth and sensitivity, pray tell you have some?
