To Wait Or Not To Wait, Thats The Question

“Trash” - with a VLF you can pretty reliably ID ferrous trash, but everything above that pretty much needs to be dug.

PI’s up to now don’t offer a reliable way to ID ferrous targets.

The Impulse offers a totally new approach to doing that, but only usage in the field by experienced detectorists will tell how useful it will be and what settings and modes are most effective for that.

The Impulse AQ is not a diving detector. True diving detectors need waterproof ratings well above the current crop of beach machines with the exception of the Excalibur and CZ-21.

 In my experience in the water, I rarely exceed 3 meters deep, to hunt since things are not usually beyond 10 meters from the shore, the Mediterranean is shallow.

Regarding garbage collection, I learned to discriminate with the ear! All sounds are different gold, silver, lead, nickel, aluminum, iron. also gold with iron sounds different, gold with lead and yes.

the truth, the few times I have used an impulse I have gone crazy, I have only used cz, excalibur, sand shark, and garret be hunter, I leaned by cz to see that it was easier to detect their sounds and did not exclude the mixed gold with other metals, being that excalibur eliminated them completely.

I am very observant of the seabed and I understood how the tides move, with this focus on the accumulation points that usually never change and things come out again and again.

I already have in my mind all mods to transform it in a good dive machine.

Believe me, the biggest question right now for me, still remain how to use seriously a 7Ms delay in saltwater.

I'm able to remove small copper plated iron cents on my TDIbh misadjusting the GB and to leave gold safe under big coins that I don't dig.  (Thanks Steve!).

The threshold drift at 10Ms is sometimes a pain however, even with sensitivity on 70% and in really shallow water.

Hopefully a stable threshold will be the key for this machine.

I know the ferrous/non ferrous target separation is at it's best due to the videos.

Now I only need to test one of the first that will be here in Europe to sleep in peace?

There are various styles of water hunting.   But it can come down to time vs pay off.   During recent drop times here in Fl most want to cover as much water as possible thus a VLF.... but in the winter that can all change.   Extreme high and low tides GATHER targets or sand is moved which can release a  concentration targets.   Working an area at that point can be more productive.   Some just like digging every target..... but the amount of trash might dictate VLF or PI.   Kind of like the Nox....... some just dont want to dig micro/small gold.  Thats where a deeper machine could be very useful especially with disc.   A few inches can be huge and add a lot of gold for your yearly total.    Then ..... there is the cherry picker..... who just digs what he THINKS is gold..... how they do that is beyond me.   This machine could give them a problem ....... as well as back problems lol.  I think a lot of the good hunters will know even before the purchase of this machine where it might work.   The surprise may come IF its disc with great depth over what we are currently using........ then it could become more useful as a daily user than a niche machine.

I'm curious about a tdi beach to see if it has more depth than a cz? if discrimination is so effective?

Daniel, depth is not a problem believe me...

You only need to fine tune the machine to obtain a stable threshold with lowest Delay and 70/80% sensitivity.

The ground balance can change the sound of objects between low and high conductors.

Try a 10 Euro cents coin and slowly turn down the GB to 4/5. At a certain point it will sound like too high (low tone)..Anything under that will be little rusty iron, stainless steel bits and rings, bottlecaps,gold rings and damned 1,2 and 5 Eurocents.

There's a way to remove it...but really risky.(You can miss big wedding bands.).

All these settings are ONLY available IF and WHERE the water is not that salty and the bottom not that mineralized.

Keep in mind, for a real ground balance, the same principle will happen turning up to 7 the GB. So other more conductive coins will be included as lower conductors.

The low/hi switch is been removed from the original SL box and on the TDI/BH works this way and only with GB on.

the electronic part / the pcb
had been frozen the first time
in january 2019
but the leap forward,
spectacular obtained in May 2019
on rejection mode = closing of all holes on gold detection
and possible 24k detection (in rejection mode)

led to an upgrade of the PCB (serial version frozen in October 2019)
it would have been stupid (for FTP) not to do so...

the only problem left
and delays launch is purely mechanical
for once, FTP is not really at issue
it is (it was) a part under contract
easy to guess which one (don't ask me ....)

I now things move slowly at FT but is is obvious to me that at this point it is more than a mechanical issue.  I'm beginning to doubt whether the AQ as it is currently will even launch.
