TDI BeachHunter Intro 

Nobody else has a waterproof PI that can do what this machine can do.

Withes TDI series are the best PI detectors for a daily hunting . For a specific hunting on very deep targets it is the Garrett ATX big coil. I have got them both . Underwater I prefer Garrett ATX because of its telescopic shaft and its very good pinpointer

I confirm . That is very much true . White's should take this in account if they wish to remain the run at the first place .

In mild to moderate ground the V3i is the machine to beat in my opinion, but it does have a weakness other than lack of waterproofing and that is the level of crosstalk between frequencies that make it exceptionally difficult to ground balance in harsher mediums, and as a result it also doesn't keep up with rapidly changing conditions like you'd have on the beach going from dry to wet sand and wet sand to submersion in moving saltwater. From my understanding this was only a minor-moderate problem before the i update which slowed the tracking even more for a better ID. The V3i is my preferred inland tool, but they make better tools for the beach. This seems to be one of those better tools.

The NOX or any Multifrequencies vlf cannot overcome very high concentrations of black sands . They have a limit ...A purist knows that ..

The NOX is not such accurate as it should be in discriminating targets on the beach ... The CTX 3030 is much more accurate !

I think this is due to the danger of fire of the Lithium technology.

Battery selection was something we looked at in depth. The Lithium-Ion batteries present a shipping hazard as well as a danger in the water, and we'd also have to modify the housing to use them in this machine. Performance-wise you will find that this machine is somewhere between a TDI Pro and a TDI SL, though with a very stable threshold.

White's Electronics, Inc. Sounds great, Thank you for the reply. Greetings from Australia. 👍

In our testing depth was in between the SL and Pro due to the hardwired coil connection.

The TDI BH makes a warbly sound on iron that is easy to learn.

That makes me so happy to read this ! Bravo !
