TDI pro beach ?

What's the best way to set up the tdi pro for salt beach? I hear mixed opinions about ground balancing or not ground balancing. Any help is greatly appreciated thanks

IF you can operate with no GB you get the best depth.

GB off should not be a problem except maybe on black sand - by far best depth that way.

You can always smooth it out with some delay or low (or high) threshold. Deep as it is--the conductive salt with bring up responses even deeper. Haven't had mine in yet can't wait.

Thanks for the help I appreciate it, I see more and more excals and ctx's on the beaches I detect so I'm determined to learn the TDI pro and hopefully get the stuff they can't reach.

Thanks John

I run mine with GB off and gain 6-7. I've been amazed at what comes from 6-10", my first silver at the coast came from the TDI SL.
If black sand is a problem I bump up the delay a tad.
Amazing machine.

To build confidence, bury a few items, with fishing line attached "of course" and play.
Way outperforms the best VLF machines in the set sand areas.

I run mine on the east coast with no ground balance, gain at max. Beaches are so heavily hunted that the vast majority of targets I find are at 8+ inches. Prepare to dig a lot of deep holes. If you don't already have a sand scoop, get one. They are much better than a regular shovel, especially when you get to the wet sand areas where you start to see water in your holes.

One thing I noticed about the TDI Pro - when it's powered ON, any other metal detector running close by to you seems to get blown away. Discovered this on our local beaches when other metal detectorists got close to where I was detecting throughout the day - they had to move further away due to interference. Their magnetic field didn't bother the TDI Pro when they got close to me, but the TDI Pro's magnetic field sure seemed to affect their detector's operation. Just an observation.

My first salt trial with this machine was disappointing--it really sounded off in the surge. I've since done a lot of bench testing and discovered that the settings I had were way too low. The Pro can be run down at 11:00 o'clock Gain and 1:00 o'clock delay and still perform well. The key is in the threshold--when it's turned way up the faint range is much more available. don't live on the sea looking forwards to another try. Given that the GQA2 and CS6PI run smoothly down lower than 17 uSc it's still a surprise though.
