Most helpful review for Teknetics T2 Ltd

6 out of 10
I own 20 different detectors and have been hunting for 20 years. Small coil works well and the 11 DD is nice for covering a lot of ground. The built in speaker is a toy compared to a Whites unit. You cant get any depth unless you crank it up and when you do it chatters all over the place. No back light, no memory, and very cheaply built, not worth the 1K. It just sits in a box in the garage because if I try and sell it I would loose $600 on it.

Best detector I’ve owned.
Got myself the GMP about 5 months ago, and I am very pleased with the results so far. I've been detecting for nearly 17 years now, and have used a Tesoro Silver Sabre 2, a whites DFX, a Golden Mask +3 (hideous machine!) and more recently, a Laser Hawkeye. The GMP is definitely my favourite machine to date, (once you get the hang of how it works). I have found more hammered silver coins with this machine in the five months I've been using it, than I ever found with any of the others!

I think some of the reviewers here who have mentioned the GMP being unstable, may have been trying to run it ‘too hot?' I know the sensitivity has a mark that says set it to the 3 ‘o clock position, but that only really works on clean ground, where you can run it that hot! The ground I detect in the UK is pretty contaminated/mineralised, and the hottest I've ever managed to run the sensitivity is at the 1 or 2 ‘o clock position, but a lot of the time I'm at 12 ‘o clock, and sometimes even as low as the 10 ‘o clock position! This is not a problem though, as in air tests show that you can turn the sensitivity right down if you need to, and the loss in depth is negligible.

I wouldn't recommend using this machine on the beach, (definitely NOT on wet sand) as this machine was never designed to be a beach machine in the first place. It excels inland though, as that's what it was built to do!

Where this machine really pulls it out of the bag, is on busy iron contaminated sites, like Roman and Medieval settlements. I now have the confidence to slow right down, and get in between all the iron, because that's where the goodies are, and I KNOW that this machine has such a fast recovery speed that I WILL find stuff there! In the past, with any of my other machines, I would have just walked away from those areas, because they would have either become too unstable to use, or just nulled out due to iron overload.

It's a great machine in the right places, but then like any other detector out there, no one machine is going to cover all the bases! Use this detector on the type of ground it's designed to work on, and everyone else will be eating your dust!

As regards setting it up, the accepted wisdom is;
Sensitivity: 12 ‘o clock
Ground: 11 or 12 ‘o clock
Silencer: 1 (but 0 if you're needing super fast recovery- 2 if you're on quiet ground and want that extra depth).
Iron Volume: Try it at 10 ‘o clock to start with.
Iron Threshold: Start off with it set to 12 ‘o clock.

This is a good basic starting point for the settings, and you can raise or lower them as needed, to suit the ground you're on.
If you're plagued by ‘false' signals, you're probably trying to run it too hot! Turn the sensitivity down a touch. If you're getting ‘false' signals each time you knock the coil on the ground, then you've probably got the ground reject set too low. If you take the time to learn this machine and set it up right, then you'll be raving about the GMP as much as I am!

I hope this helps, and good hunting, whatever machine you choose. :)
