In city conditions there is too much interference for a pulse detector anyway.

Mark, I'm not sure about other VLF detectors but I do know that my GMT has a iron discriminator which tells me how much iron is in the target.? The other problem with gold machines in the city is all the aluminum but on my GMT aluminum makes such a sharp high frequency sound that I can tell right away it's aluminum.
At Franconia I know almost immediately if I've swung my detector over an aluminum bullet.
The discriminator switch on the GMT is great for Franconia because the Sacramento Wash 005's make a zip-zip sound, the basalt makes a grunt-grunt sound and meteorites make a zip-grunt sound.

I also have a 6" by 8" coil for weeding through areas of high trash.

If you only have an hour to hunt a park, that could mean the difference between recovering 30 coins with a DFX, or 5 with a GMT (with a lot more junk recovered).

Since I bought a coin machine, I've done a lot more detecting because the gold/meteorite fields in my area require at least a day trip. I can fill a hours time now (or even less) and find some coins/jewelry.
