Anybody Used The TDI Beach Hunter In The Gold Fields ?

Recommended Posts

Whites quoted on their website that the TDI beach hunter can also be used as a nuggett hunting  detector in the gold fields. Was wondering if their was somebody who tried it and what their experience is and what the sensitivity on small gold is?

The electronics in the TDI SL, TDI SL Hi Q, and TDI Beach Hunter, are the same circuit board.
The TDI Beach Hunter is locked into the ALL CONDUCTOR mode. It cannot separate low and high conductors liker the TDI SL.

Hope this help.

Good Luck😎

Sincerely

Hamid

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.

Whitbey in theory the Tdi Beach Hunter should to some extent operate like a Tdi Sl mounted with the 12 inch Duel Field coil with conductivity in ALL. Having said that, it means in theory it should work reasonably well on the goldfields. I have used the 12 inch Duel Field coil on the Victorian goldfields on a Tdi Sl, took a bit of time to get the ground balance 'just' right, there was a degree of 'ground noise' that had to be endured.  Due mainly to the size and character of the coil compared to a smaller mono for example. With my experience on the SL with this coil I conclude by stating it will be more work to ground balance and  operate but it is still fully functional despite being a bit noisy.  Since the coil wasn't hardwired I did swap out for  a smaller mono which was easier to ground balance, ran smoother and was more stable. As Tony state the machine may well be pushing its limits if the ground becomes very hot and you would be better served by other machines. 

 Until you actually try it the question remains. You are not the only one asking this question, particularly in the USA were the soil conditions are perhaps less severe than those encountered by me in Victoria Australia or by Tony in Western Australia. The ability to take your beach machine into the goldfields is a bonus, perhaps into the rivers and steams in those areas.. certainly an area worthy of exploration.  All the best.

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 !

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 👎

Thanks very much Tony for testing the unit, you saved me money and I will not by the TDIBH. ( Buyer Beware )

      So what would I dream White's would add and change on the Tdi Sl. Interesting to see what direction others would like White's to go in.  
      Not asking them to reinvent the whole system, just significant tweeks to breath new life into the Tdi machines.
      1.Keep the light weight body. A well balanced detector that is super light and easy to swing all day.
      2. Replace the mounting setup, like the old Tdi Pro, please use screws so I can hip mount the detector quickly and easily.
      3. Keep using the same battery system, just upgrade to a 16 volt rechargeable, or 4 x 18650 system. Extra voltage matched with upgraded components etc Push the boundaries..
      4. Retain the compatibility with MInelab coilts etc.
      5. Upgrade the ground balance please, fine and course.. or a ten turn.... makes a big difference.
      6. Yes I admit this sounds like a Tdi Pro in a smaller, lighter and better balanced rig. Only dreaming but far from impossible. Nothing mentioned here that has not been done by owners in the past as           modifications of existing White's machines.
      I can live without hipmount on such a light and well balanced machine, I've already pushed the battery system to max, at 16 volts. I'll keep a lazy eye out for a solution to the ground balance knob, I've seen a two tier knob etc. Just dreaming.

      In a previous post few years ago, I read where a forum member I think it was REG was stating he had given Whites the information on how to do several modifications to improve performance.
      I think this was about Dec. 11, 2016   1. build battery pack using Panasonic 3400mah. 2. modify filters to allow for faster swing speed. (reduce value of c20 and c21 from 0.47uf to 0.22uf).
      and a few other changes. 
      After that said,  the TDI SL I just purchased shows it is a 2015 model. Am I correct in thinking these mods. were not done at factory? I am going to open up my unit and check c20 and c21.
      Also I purchased a Minelab Commander 15"x12" mono coil to try on my TDI SL. for Saltwater beach moderate mineralization. Will this improve performance better than stock coils or should I look at better options for the coil choice. I was hoping to also use for relic hunting at some old camp sites.
      After speaking with Jim, I have ordered the Panasonic 3400mah batteries to build my upgrade pack, and if need be will try to mod myself.
      I am new to this forum, have been hunting since 1994 or 1995. got away from detecting for a while then came back to my senses, forgot the motto you work to live not live to work lol.
      I have learned more from reading the forums that I have ever learned by my mistakes. I hope I can contribute something to this forum and pay forward for all of the ones that have helped me!

      Hey All, Measured White's TDI SL factory battery packs and discovered the following differences. 
       
      NiMh Battery - HD #802-5321, 2200 mAh.
      After full a charge, one day later..........................................10.99 VDC AA Battery Holder - #802-7150, 8 cell.
      With Nuon Industrial Alkaline from White's Factory............12.94 VDC With Member's Mark Alkaline from Sam's Club...................12.96 VDC With Energizer Ultimate Lithium...........................................14.46 VDC  
      Was very surprised that with Alkaline batteries, the tested voltage was higher than with the NiMh battery pack.
      Also, the NiMh battery pack seems to drop about 0.05 VDC a day.
      But the clear winner are the Energizer Ultimate Lithium batteries at 14.46 VDC!
      Stay Safe!

      Hi All,
      Has anyone tried the Coiltek 17x11 Mono on the White's TDI SL?  Would really appreciate any feedback on it's performance.  Also, the Coiltek 14" round for the TDI?  If positive, I'll order one and report my findings in a couple of weeks. 
      Maybe the battery mod later...  Also checking on the SteelPHASE SP01 to enhance the audio...they said it would help.

      Much appreciated,

      This coil is being advertised at quite a few dealers now for $179.95. Which is great, available now for existing TDI owners. I had to chuckle though. They all are advertising it as “Whites 7.5″ x 12″ TDI HI-Q Dual Field Coil for MX Series Metal Detector”
      Makes me wonder sometimes if I am the only one that notices stuff like this.

      When circumstance allow, I like to go prospecting in Victoria's 'Golden Triangle', one of Australia's nugget hot spots. I use my beach machines, a Tdi Pro and a Tdi Sl Limited Edition. The Pro can be used for prospecting without any real issues, the Tdi Sl is more challenging in this environment. I'm going to focus on my experiences in hot ground, infested with ironstone, hot rocks and heavy mineralization. Not going to focus on depth, power or anything other than what it takes to get the machine to operate smoothly with the correct ground balance. The Pro machine has a hugh advantage, simply by vitue of that course and fine ground balance adjustments but this post is mostly about the Tdi SL. The single turn ground balance on the SL is a pain, it takes a bit of time to get it just right.
      When the ground is hot the SL requires me to use a smaller coil, mono being the best. Mono coils in my experience are quieter, more stable and much easier to ground balance. Larger folded mono coils, duel field coils and the newer and hotter spiral wound coils all suffer when the ground is very hot, they are noisy and difficult to ground balance with a Tdi Sl.  The Tdi Sl with the stock 12 x 7 Miner John folded mono can be balanced but it will transmit more ground noise and be more difficult to ground balance when compared to using a smaller mono coil. Forgive me but I'm going to repeat myself a few times in this post.
       The smaller the coil the quieter the Tdi Sl will be and easier to ground balance, the reduced 'foot print' helps a lot. The very small 6 x 4 mini Jimmy coil is amazing in its ability to run smoothly and easily ground balance, but is too small to be practical most of the time. In comparison I can use larger mono coils on the Tdi Pro without issue, it has superior ground balancing ability on the goldfields.  A Tdi Pro mounted with a 8x6 mono 'Sadie' is my standard setup. The Detech 15 x 10 or Digger 14 x 8 also see some use as does the new to me Detech 8 inch mono when using the Pro. So whilst the Tdi Sl likes the smaller mono coils on the goldfields the larger coils are not an option. Yes the ultimate Tdi Sl setup is a small mono coil and an upgraded 16v battery pack for prospecting. Super light weight and beautifully balanced, respectable performance and versatile. Fun to use for all, kids and older family enjoy the light weight and balance. 
      Allow me to deviate for a moment. Tie me to an ants nest and smother me in honey for stating the obvious. Serious prospectors are better served by more specialised Minelab machines... they are superb.  For me versatility is key at the moment and  I feel better served by my White's Tdi Pro on the beach, that stealthy little Tdi Sl 'urban PI'  is also a pleasure to use. When I invest in an expensive 4x4 and trailer some time in the future, then I'll make room for the more specialised gold machine. Hopefully by then  Minelab with have a light weight and well balanced SDC type PI in a Tdi Sl style body. Maybe White's will surprise us all. Fisher is coming to the party also. I need PI peformance and light weight, good balance and sane pricing.. more options arriving as time goes on.
      Again my one piece of advice to anyone wanting to prospect using a Tdi SL in 'hot' ground, particularly in Australia, is this.. Use a small mono coil. Small duelfield coils like the older Jimmy, 7.5 duelfield, Miner John 7x5 folded mono or 6 inch folded mono coils, are all OK most of the time.. The Razorback 10 x 6 mono is great, the Coiltek Tdi series 6 inch mono is great, The Sadie is great. Keep it small and stick with mono and you should do well in all types of ground. The larger coils work well with the Tdi Sl in moderate soils and the beach. But when the ground goes bad it does pay to swap out for a small mono.
      Again this is my experience in hot Australian ground. Hot is hot and I suspect many international Tdi Sl users have the same experience in difficult ground. Not looking to pick any fights but this is my experience with the Tdi Sl. Go small, go mono and boost the battery pack. All the best.
