I just use a pin-pointer for helping with deep targets but if the car is nearby I"ll grab the SDC or Gold Racer. I have kept my GPX for a few reasons.
1. GPZ and SDC can't be used close to high voltage powerlines or electric fences
2. I prefer to work the beaches with the GPX. Z doesn't have a salt mode and sdc coil is too small.
3. For open patch hunting the 5000 can be swung a little quicker and with a 17x13 Evo is still very light
4. I like to use the 14x9 Evo on the 5000 in very thick scrub. In that push and shove type detecting a bungy becomes redundant so a nice light combo is very welcome
But that is about it. Any other general prospecting work the Zed rules supreme
