  1. An Easter egg hunt for the kiddies along a tropical beach might sound like great family fun, but it's my worst nightmare come true.. Not that I begrudge the kiddies their fun, just go have it somewhere else (or don't unwrap your eggs and eat them the moment you find them).. For weeks now I've been digging foil.. Every time I get my hopes up it's a gold ring.. It sounds good and the target ID doesn't jump about too much.. It's deep enough for a ring to have worked its way down into the sand over the weekend.. Even when I start digging I don't give up hope.. Maybe it's a small ring a lot shallower than I thought.. Oh, it's out of the hole already, the thing really is tiny.. Every time I go through this process only to find another bit of foil.. It's beyond heart breaking.. Even underwater you'd think that wave action, tides and currents would carry light foil pieces far away.. They don't.. There's a never ending supply of foil on land.. Maybe metal detector manufactures should concentrate less on iron filters and more on aluminium filters (if that's even possible without filtering out gold signals).. I'm sure that even in the bush or the desert, small pieces of foil can be a nightmare..
  2. I wouldn't take it much deeper than 3 metres.. If you're after a vlf scuba detector that can go deeper, it's worth checking out the Deus II which stays waterproof to 20 metres.. although I've only taken mine to 16 metres, it does have a lot of submerged hours on it already (in seawater).. having said that, both my Equinoxes (600 and 800) also work hard and have never leaked even at 4-5 metres when I stray a bit deeper than intended.. As a scuba detector (as opposed to a wading detector), I'd go for the Deus II as I'm pretty sure the thing won't leak even when working it hard.. For a wading detector the Equinox is your best bet, it's bullet proof.. The Deus II is a flimsy thing and you're likely to loose your control box in heavy surf (it's easy to knock it off its perch underwater too).. The Deus II bone-phones are also rated to -20 metres..
  3. The owner tried from another phone and it didn't ring through.. but the tracker was still working.. She's since contacted me again and it now seems the phone is on the mainland somewhere.. I'm as sure as can be that it's not where it's supposed to be on the island.. I've recovered phones using info from their trackers before and it's always worked, including a phone left on a bench at a bus stop.. The usual scenario is people telling me they've lost their ring 'somewhere on the island' or 'it must be in one of the four bays we visited'.. After narrowing it down together with her hubby, one lady came to the conclusion that she'd lost her ring in a hotel swimming pool.. she asked if I could check the filters.. but that's not the tragic part of this tale: she'd lost the ring thee months before! Needless to say a fair few recovery jobs don't turn out too great.. I find a lot of rings and jewellery that are never claimed.. I also check with the island police station to see if any of them turn up on their lost and found list.. It rarely does.. I'm always tempted to start melting them down into gold and silver nuggets.. and separating the stones for a jewel collection..
  4. That's one of the many reasons I mourn its sad loss.. also for silver coins on beaches, no matter what program I'm running the Deus II, it's not finding anything the GPX or Equinox (or PulseDive) have missed.. I keep dreaming about the prospector I sold it to, hoping that he'll swap me back the GPX for the Deus II.. 😁
  5. During the school holidays and Easter long weekend I've had a few recovery jobs.. Last night a lady on holiday from the UK contacted me on my Facebook page to ask if I could recover her phone.. She was back on the mainland but the phone tracker showed the exact location on the island.. I told her to send me a map and went to have a looksee early this morning.. The description couldn't be clearer: along the path next to the big water tank for Horseshoe Bay.. The gps coordinates pinpointed the exact spot.. You couldn't wish for an easier job.. especially as there was a vague promise of a $100 cash donation for my free services.. Anyway, I got to the spot where the phone was supposed to be and ended up using my detector as a rake.. After an hour of raking the slope where the phone was supposed to be and all around it, I still didn't find the thing.. I've let her know..
  6. After only two months of use (using sound only) my dodgy non-vibrating bone-phones have packed it in.. They never vibrated and last week they stopped making any sound.. I've sent them off for a replacement and should have them back next week as it turns out the XP service centre for Australia is here in Queensland.. Hopefully the replacement vibrates like it's supposed to.. The people at Detect-Ed and XP were very helpful..
  7. Thank you for these tests Cal_Cobra.. I'll be keen too see the salt sensitivity settings in action.. just as a quick guide to how they compare to those on the Deus II.. Compared to the Equinox as a scuba-detector I've found the addition of salt settings mighty useful in stabilising the detector underwater..
  8. I couldn't find any other information on the frequencies used in these programs, yet alone the ratios.. So PimentoUK's post caught my interest.. But I'm not too worried about frequencies, I'm all about stability.. and the Deus II with its salt sensitivity settings and processing ability to filter out salt signals keeps it running pretty smooth.. Sure, it's just as 'crackly' underwater as the Equinox (I think of it as squelch) but the target signal stands out much better from the background.. It's not necessary to hunt the 'subtle whispers'.. For me, the Deus II already preforms its magic as a scuba-detector without having to find an even 'better' sweet-spot..
  9. I just read this on another thread (Deus 2 May Be First Multi Freq Multi Freq Detector....) where PimentoUK talks about the frequencies at play in programs 10 (Diving), 11 (Beach) and 12 (Beach Sensitive).. Thanks PimentoUK.. P12 : Beach; all run at 8.08 kHz & 40.4 kHz, a 1:5 ratio. P11 : Beach; all run 8.08 kHz & 24.24 kHz, a 1:3 ratio. P10 : Dive; both run 4.76 kHz & 14.3 Khz, a 1:3 ratio ( not unlike the Fisher CZ range, but a different waveform shape ) It looks like P6 / P10 run a three-level waveform to reduce power consumption, obviously important for a coil with a small internal battery. How they process the freqs is of course the important bit.
  10. I guess target ID would be too much to hope for? 😁 but if Nokta Makro made the PI detector as waterproof as their PulseDive, I'd definitely be interested.. and they should also hang onto the vibrating handle idea from the Legend..
  11. Spotted this feel good story on ABC News this morning.. About a beach and scuba detectorist in the NSW Great Lakes region who reunites people with lost rings.. A great bloke! 😃 https://www.abc.net.au/news/2022-02-23/passionate-metal-detectorist-reunites-hundreds-of/13767142
  12. This is Geoffrey Bay in 1926.. The line of trees along the beach are not there yet..
  13. This is the location of the Silver Mine.. To be honest it's more of a Copper Mine if I include all the pennies, half-pennies and 1 and 2 cents in the total coin count.. It's only in this spot that I'm finding old silver coins and sometimes gold jewellery.. walk 20 metres left or right from this spot and there's no old coins to be found.. Where the Island's first guest once house stood is now a row of houses.. I've got all silver ware found here soaking in vinegar at the moment.. It's nothing like Phrunt's Cointopia but these coins give a great insight into the history of this place..
  14. On the beach I'm sticking with the equinox for now, until XP bring out a larger coil.. but underwater the Deus II is working out just great..
  15. Here's some old footage of Magnetic Island in 1926.. I spend a lot of time researching the island's history and rely on old films like these to work out the best places to hunt.. https://d2bx93w6kas18u.cloudfront.net/titles/roundtow/roundtow2_pr.mp4
  16. These are some other bits of gold jewellery found at my Silver Mine.. They were found a couple of months apart.. The island's first guest house stood at this spot over a hundred years ago, which makes me think the gold jewellery I'm finding here is quite old (for Australia).. I usually find many silver coins here dating back to the first settlement of the region from the early 1870s onward..
  17. You're sure right about that Joe, that's a very different result compared to my beaches.. where the Deus II (with a 11'' coil) has trouble on targets buried 20-25 cm deep (around 8-10'' deep).. Wild stuff! Just goes to show not to get too carried away with what others are finding and to do your own testing instead.. 😃
  18. Here's a map of Magnetic Island with its many beaches and a picture showing what they look like in real life.. The picture shows Radical Bay and Balding Bay with the Palm Islands in the background.. It just goes to show the huge variety of beaches people hunt on.. This is also the reason why my tests must be taken with a grain of salt (pardon the pun) when comparing them to yours.. My beaches have a fair amount of black sand as the island was born when magma pushed through cracks in the Earth's crust to form a dome, this dome has weathered down to what the island looks like today.. The island is made up of many different sorts of granite, including the sort that formed gold (there are 8 old gold diggings on the island)..
  19. You were spot on with this one Phrunt.. I'm more impressed with the Deus II as a scuba detector than a beach detector.. And there's also a happy ending to me selling the GPX 5000 to buy the Deus II.. The prospector who I sold it to already has the GPX 6000 and GPZ 7000 to work his claims around Georgetown, Forsayth and the Palmer River, but he's always had a soft spot for the 5000 because of it's huge range of coils.. He's no small time operator, he's got the big machinery out on his claims to process as much dirt as he can.. He's been prospecting for 22 years as a interest and turned professional 6 years ago.. When he told me how much he made from gold prospecting/mining, I nearly fell over backwards.. Well into the tens of millions.. Anyway, he invited me to come hunt on his claims.. He'll even lend me back the GPX 5000, so I'm using a detector I'm familiar with.. So, all's well that ends well.. 😃
  20. Sorry Phrunt but I'm done testing.. 😃 Just going to enjoy both the detectors for the time being.. The equinox on the beach and the Deus II in the sea.. But I will keep on posting any queries or observations I have on the Deus II.. Judging by some of the videos coming out by prospectors, it seems the Deus II is also not much chop on small/tiny gold nuggets.. As I've mentioned, I also have some reservations about it as a beach detector compared to the Equinox, a larger coil makes all the difference.. But as a scuba detector it's working out just great.. Mission accomplished.. 😁
  21. Here's a test of the Deus II vs the Equinox on a 1943 silver shilling.. This is the reason why I use a large coil on the Equinox.. Although I would've dug the target with both detectors because of the high readings, they did jump about a fair bit between numbers (if it wasn't for the high numbers it could have been a bottle cap, they jump about too).. Both detectors are at full volume.. Also notice how much the Deus II shaft wobbles when extended..
  22. I've just tested this on my beach.. see my thread comparing the Deus II vs the Equinox.. I've made some videos, I'm sure the results won't surprise you.. 😬
  23. I do have a bit of a concern about the battery life.. now, before anyone jumps on me, I do know (having read the manual a million times) that the coil battery drains faster in the Diving program, and that the control box battery drains faster when you've got the bone-phones attached.. But I didn't realise how fast.. Yesterday at Horseshoe Bay I checked the battery on the control box to see how battery was doing before diving (the coil was fully charged the night before).. it showed 1 bar on the battery meter, but about 20 minutes into the dive the Deus II died.. This is no great disaster for me (more of a pain in the arse) as I'm at most 5 minutes away from home on the island.. But it does compare badly to the Equinox battery which holds its charge much longer underwater.. Could this be because I'm running it with the volume turned up so high on the bone-phones?
