Skull diver

I'm probably not so far to the solution of our trouble... After a quick search I managed to find an old model of a Coiltek waterproof rated coil also produced in a DD version... Cause I dive with the TDI BH, I want a fully waterproof and most important not floating coil, I have found the 12"x8" Platypus mono to be the better choice talking about dimensions and type of shell : opened, elliptic and epoxy filled)... As for now, I only need to go over some questions in my mind: 1 Is the coil inductance really the same for the TDI SL and the GPX? (I think not)... 2 Will the swap operation really improve the noise/signal ratio in shallow saltwater, remaining on a 12" shell even if the 8"side is what is really relevant? (I'm only sure that a dual field is a different thing and a plain mono will do better...I hope)... 3 Will the coil with less windings than the 12" yellow dual field (not so correct affirmation i know), operate better than now with a lower pulse delay of 10mS? All million dollar questions for the real experts we all have here........ Please.........and thanks in advance to all who will help me to solve the problem...

For the same reason I'm really thinking to adapt an 8"mono to my Beachunter. Actually I want to build it by myself if possible...I've seen that this GPX/TDI specs for coils are not so identical... Needs to know all details before to do a complete mess 😂

Water hunting is a bit more easier cause of a different trash/value ratio. On the wetsand is another story, on the dry is a movie for patient mens. If you think to the factors involved to have results on the beach, is probably easier to find a nugget with some luck, even a small grain. I started to find gold when I quitted to search for gold... Since 2012, I hunt for conditions, from a desk with a PC... Before even to think to go downthere.

Between the two, You're doing already better than me for sure🤣...To feel an old sensation and to hope for the next days, I'm posting a picture of one of the few memorable days in the last years...

Lots of cheaper detectors due to the moment and unluckily a lot more crap terribly advertised even years before. I do the work for 💰 underwater and I feel a little neglected by Minelab. Prehistorical Excal 2: blind to fine gold chains (sold 2 of them),a trusty 8 years old Ctx, almost outdated and is not so good in depth (14x9 Australian signed coil)9 against even the Nox with 11" coil. The Nox however is far to be even slightly similar on the VDI stability (and type), so for this reason I decided to keep the CTX on, otherwise there's nothing new under the sun. The fuc....g Vanquish the world was waiting?I keep silence about it...

Well, it happened... I was finally back to my war room in my mother's home, looking for stuff to move with me after lockdown end and I've seen again a pair of Grey Ghost Underwater abandoned over my old bed. I never asked too much talking about headphones, but the crap still remains crap even with other colours option. Overpayed the Ctx3030 8 years ago cause of this horrible low sounding things (at volume 30), and never used successfully till changed with yellow Koss (same substance in another color nuance, just slightly better audible)... Underwater the faintest sounds are too hard to hear and I don't like the volume gain maxed out losing perception of real signal's depth. I also changed pitch profiles from low to high Mhz on gold range, to allign in mind and memorize the same audio reaction of my TDI bH...Nothing, these headphones are probably maded for other brands but on Minelab stuff, you can use it as a replacement for noise insulation 3M Peltor just cutting the cable. I found this interesting post with some piezo specs... My question is...Can I try to think to modify by myself the stuff or a baseball bat shot will be better? I'm a crazy pirate, so laugh with me please😅

Congratulations to you for the effort, cause people can enjoy the numbers and improve skills... Talking about "us"....All I can say is: 1 I don't trust Minelab Id scale numbers of today (both tested NOX 800 and Van540)... Slightly better the Nox, but if you sweep the coil a little faster the 540 is crap to understand wtf there's under... 2 looking for precious stuff,transformed me in another kind of hunter (the worst), so that I'm never so satisfied of the instrument and even of myself for multiple reasons... 3 in all honesty, I'm seeing the market failure talking about quality/price ratio. I hate to call myself a professional and I never forget that is only cause cause I probably don't have much other choice to earn real money in my life... 4 my real valuable experience today, is to know that I've done terrible mistakes and multiple times.... Message for the world ❤️ never trust too much the fu.k.ng numbers...

Nothing so special here, just a common 18k wedding band, really usual in Europe. I'm satisfied to see again gold after over two months of Covid Lockdown😷. The amazing thing is from where I pulled it out. I've been totally shocked by the use of a compass today, cause I found too much times myself uncapable to keep straight lines underwater in murky or windy conditions. So today I was testing not only the use of the instrument, but also a new weight harness I maked to relax my poor back and what a relief! I'm now doing snorkeling without fins and a neutral buoyancy trim. The place was a terrible one, rocky, aluminum infested, uncovered bottom by months and deadly pounded by competition of other locals... Before the lockdown I cleaned up the last drops of gold remained, when they were saying me "is over..don't do it again" and laughing,leaving me alone there: (terrible mistake💀😉)... At a certain point I was next to leave, when I decided to follow another line on the compass to come back to the shore... Thicker Sand, freshly deposited, no referral things to take note of, but......Bang! When I heard the CTX to punch a solid 12.24 I was amazed and already sure about the shape of the thing...In the middle of nowhere.... The end of the story is...I've been fooled by myself dozen of times, never been really able to cover entirely hot points in patterns and potentially leaving lot of good stuff behind..I'm sure about it cause I frequently passed again like in a circle from same spots already checked... To hunt wading is another thing than snorkeling or scuba diving. I have proof now that a compass can make the difference when I need to cover bottom in the right way. I'm noticing this fact after "only" 15 years😭....Take note and apply.....Hard payed experience....

How much I miss days like that! It reminds me some virgin like places back in 2015😭... Well Done!

Actually I have the same doubt 🤔...Is a bit weird as I found on Amazon the coil straight from Detech factory and there is TDI mentioned...On their website (dedicated one for Italy)also appear wrong coil (same dd picture with different details), but also the bolt hole seem to be for Minelab and not for White's...What can I say....Need to contact the factory to better understand what they say about...

Thanks a lot for your words about it! I'm oriented to an 8" coil, (Detech mono)especially cause I dive and always try looking on Rocky environment when the erosion appear. I learned in the past that a smaller coil can be pushed higher in sensitivity, so the perfect size will be 8"for me... Hopefully in the future i'll be able to reduce the higher delay of 14ms to 10ms and don't hear too much drift noise changing the coil.

Jeez...I'm in love with this post! I'm looking for another coil on my TDIbH cause of saltwater (shallow) bad influence on the original one... It seem that only with higher delay the machine is able to divehunt silently or stably in threshold... I use however the ground bal only as a sound discriminator between high and low conductors, as the sand and the bottom in my coast are not so bad to require it. My question is...Can I still use the two sounds mode with a mono coil?... Actually I don't remember why, but there's a post somewhere wich talk about this thing...I think not🤔... Hardwiring outside from the control box a real good waterproof male/female connector will be the hell's second phase for me💀🤣

No comment...Just an update I wanna share with all of You in this ship....

minelab Daniel😁

These words from You are encouraging me! I'm too, looking for a real hunt planning method. Trough the last ten years I've been able to isolate some hot spots in my coast doing an expensive analysis not only visiting every single Bay or corner, but also diving there with tremendous effort due to the equipment on my back (almost destroyed at 37y.o. age)... Still remain something to improve, 90%of the time not for my fault, but I'm next to know the potential "shine' bulletin". I'll be curious and honored to try with somebody from any coast in the world, to test my method with exact spots coordinates. I only need a zone name to report back news about the area...

Perfectly explained! As a diver, I'm really bored of a too old board like the Excal. Actually I sold a couple of them 7 years ago to replace with a Ctx. I hate it, I love it...I need it waterproof for real! Vlf or pulse is not that vital, but come on Minelab! We are a damn neglected race.

What an incredible story. There's enough to make a movie. This will be the right mindset. Continue hunting with or without Impulse as soon as the coronavirus lets us out.

I'm really sorry for the ruined experiment... But...I think there's at least an hundred sharks ready to bite for a fake news like this one 🤣

Just hope this will be the real day for the machine launch. As I already writed an article on it (thanks to Rick and Steve permission)and is time to make it real for all those that are waiting this miracle.🤐

So...April 2nd to see an official launch video somewhere?🤔

it seems they were on a budjet🤣🤣🤣

This was actually my doubt too...Glad someone other asked for a pulse delay update regarding salt underwater use... With a good drift noise reduction and a stable threshold I'll feel a lot better.....just remain me to...WAIT

I've done the same thing...And appeared to me like was an abandoned web domain...Jeez....2020 and it seem like '90stuff.

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.

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😁
