Can a modded GPX beat the SDC2300 and GPZ7000?

Woody,
Anyone half believing that garbage out there you can point them to me and I'll be happy to endorse the work that you have done for me over the years.
You have my email address if required.

Woody, read your above explanation of what mods can do, but as a layman to electronics, I'm still lost. Are your instructions that come with the mods available to read anywhere?
Thanks, Shep

Hey Shep. Merry Christamas! With the detector in hand, it is pretty easy to figure out. Crank the new gain control to 8 to 10 on the dial, if it starts the get unstable, back the gain off a turn or two. As for the frequency control, if you are running a small coil working in shallow ground, run the frequency up in the higher numbers. If you are using a big coil for depth, run towards the lower numbers. It works pretty slick really and I am very pleased with the results. I haven't tried using a double d coil yet as I don't normally use them but in really hot ground one would probably work very good.

Buffalochip, thanks for reply. Still abit lost with your explanation.
On the mod I got, I have a 3 position switch on front cover. When you set gain, is this another dial somewhere? Pics would be handy
debongos:
Hi Shep, the front end gain control is another mod. The three switch settings on the front cover is an original mod which I have on my SD2100. The latest mods are the front end gain which increases sensitivity of your coil and the control is placed on the front. And the second is the variable frequency mod adjusted at the rear and I have these on my 4500.
