At the 2:00 mark..........I couldn’t help but think that it could “flat line” 😳

Tarsacci was badly falsing in between the targets so sensitivity was way too high. Other machines were nice and quiet which means they probably had some power to spare ? Good test really especially swinging in between targets to gauge falsing.

And here’s me swinging my XL Pro...........and loving it 👍

“A man can never have enough detectors”..........obviously you haven’t met my wife 😳

You are welcome......how’s the ground in your area ? If it’s quiet then the TDIBH might be viable ???

Okay....results are in.....and it was an ugly experience for sure. No matter what setting I tried, even with low gain and increased pulse delay, the old girl screamed her head off. The ground was quite mineralised so in benign soil then things might be okay but in traditionally mineralised goldfields then it is a futile exercise. The GB didn’t stand a chance and I think I scared off most of the wildlife In the area......time for a cold beer to steady my nerves. Now in parts of the USA, a lot of gold bearing ground is in much, much milder soils so that might work out. Do your homework before venturing to new ground......if it’s anything but benign ground.......don’t take the TDIBH 👎

Yep.....that was some years ago ! Keep well Tony

What I will do is take my TDIBH to an area of high mineralisation.....it’s not too far from home, maybe a 20 minute drive. Just waiting for the weather to cool off first. I will put it through it’s paces and we’ll see what happens....stay tuned !

Separating high and low conductors when looking for a wide range of nuggets (sizes and purity) is risky as the crossover point ties in with where the GB is set. The TDIBH has the power but the GB range/resolution will be problematic in highly mineralised ground.....which down here is very widespread. In milder ground then it might be okay but if you are serious about nugget hunting then there are much better options out there.

And this is why I got the Whites TDI BeachHunter almost 2 years ago. An actual unit in an actual box with actual performance. I feel the performance of the AQ probably wasn’t going to surpass that of the TDIBH but was going to “have to cost” at least twice as much.........and that would have dire consequences. I just have this bad feeling about the whole AQ project. ...............and I genuinely hope I am completely wrong with everything I have just said ! In the mean time, my TDIBH is sniffing out gold way down in that lovely deep layer of compacted shell and fine limestone. Don’t sit on the fence deciding or waiting what to use......get the best you can today

Only deeper if conditions allow for the TDIBH to be maxed out.....in surf and waves then it has to be detuned and then you have the 12” coil to deal with. The SHMK2 is a better choice in these conditions. On the lower beach and hard pan then the TDIBH is probably the best there is.....for now.

Checked my records from my previously owned SHMK2 with the big coil..... my wedding band was detected at 14”. The TDIBH running at the higher voltage (14.8v) detects the same ring at 18”......I also found that the bigger coil was only slightly deeper than the 8” coil with about 1.5” depth gained on coin/ring sized targets. The SHMK2 is one of the few detectors that I regret selling. The toughness of it and the confidence in the (leak proof) battery area and that little powerhouse 8” coil in the surf and waves is the best in the business. I remember that the male pins on the headphone connector are quite delicate and I broke one off. I had a spare set of headphones which I swapped out.....another SH strength in its overall design. In rough ocean conditions, the TDIBH with the big coil is a bear to use and has to be powered down via Gain or Pulse delay. I can see myself acquiring another one of these great Garrett units.👍

With the extra voltage pack, the TDIBH is a good 3” to 4” deeper than the SH MK2. The hardwired TDIBH coil helps get some extra punch over a removable coil cable.

Thanks for that......so this one (4S2P) from Batteries Direct would suit the TDI Pro. I have the 4S1P for my TDIBH.......half the one pictured. Ouch...they want $166 for the pack !

And I’m hoping you don’t let any smoke out of the TDI........👍 Tony PS....is the TDI PRO powered with those standard barrel connectors and the SL the standard Whites AA holder?
