In my opinion the TDI Sl is the best beach machine I've ever used. So far this year I've dug a lot of coins ranging from 3-10" deep, all gave a good signal. I love the ground balance turned off, pulse 10 and gain at 10. So stable and quiet, no emi where I've hunted. Dug my first ring at only 6" deep, eventhough not gold I'll take it. Did find three round pieces, all completely encrusted, very simular to a quarter after removing the outer shell, but nothing I can ID on. One thing I've learned, if the sand is so soft that it leaves foot prints, move on. Hunt the areas where the sand is packed about 1/3 to 1/2 the way from where people hang out toward low tide. Happy SL user.

SIGNAL COMPARISON: REIDMAN VS. WHITES (3 replies)
Okay folks,
I have been ITCHING to see what putting an 18 volt battery in the TDI PRO would do for it's depth and stability. To achieve maximum allowed voltage in the pro, five 3.6 volt cells are wired in series. This is the battery Reidman makes. He gives it a balance and protection board too. The battery will discharge evenly, charge evenly, and cut off before the batteries are drained too low (draining them too low can ruin them). It certainly gives more peace of mind than the stock battery, having this protection. But what about the performance? Does the Reidman smoke the Whites? Just how much of a difference does a 25% increase in voltage do for depth? That is a significant increase in voltage, by the way. But strengths of fields generally drop off with the square or cube of the distance. Some drop offs are exponential. To expect a 25% increase in depth from a 25% increase in voltage is naive. I did not anticipate much of a difference but I am a depth hog and just had to know exactly.
The setup: stock TDI pro (no "Reginator" mods yet, waiting for warranty to be up), stock dual field coil (12 inch). Not mono. NOTE: I anticipate any depth difference between the whites and Reidman battery to be lessened with the dual field coil. With a true mono coil, there will be a slightly larger difference in depths between the two batteries (Reg correct me if I'm wrong). BOTH BATTERIES WERE AT FULL CHARGE WHEN TESTING STARTED.
I have been hunting high conductors on land recently since low tides have been at the worst time (4 AM). I have found more silver than I ever thought was possible with ANY detector in my area. I have rediscovered my love for land hunting with this detector. Thus, I wanted to push these batteries on a deep dime.
Test 1:
Target: Clad dime (shiny, no patina).
Depth: Eight MEASURED inches. MEASURED. NOT EYEBALLED. NOT APPROXIMATED. NOT GUESSTIMATED. Measured. I dug this plug with a predator model 25 (raven) shovel. The plugs this shovel digs are works of art. Important: this plug was dug only after checking in straight pulse mode that there was nothing around to interfere with the dime.
Orientation of target: target was oriented with the ground. In other words, the dime was not on tilt.
Settings of detector: Full gain, 10 us pulse, conductivity switch to high, GEB fine minimal (barely on), GEB rough zero (defeated). This is an extreme setting for the GEB that will throw even the nastiest of iron into high tones, allowing one to focus on the "true" low tones. If you want to put a fat, honking smile on your face, go swing at the local park with these settings and watch yourself take coin after coin others have missed. It is ridiculous how successful I have been with these settings.
The Whites battery yielded: soft, repeatable tone. You could tell the depth of this dime was nearing the limit for these particular settings on the detector. Moving the coarse GEB to 12 o'clock made the signal much stronger, and would have been impossible to miss even when swinging fast.
The Reidman battery yielded: when I first changed to the Reidman battery I went "oh yeah, that's good, that's real good, that seems much stronger." I ultimately ended up switching between the reidman and whites about five times, carefully listening and trying to discern differences. Because I had to listen so carefully, it was immediately clear that there was no significant difference between these two batteries, and that my first impression was wrong, I could not immediately tell the difference.
I decided that burying the dime deeper, right on the edge of detection would more clearly bring out differences between the two batteries. I dug a little deeper.
TEST 2:
Same target, same settings (minimal GEB, conductivity switch to high, 10 us pulse, max gain).
Depth: now a MEASURED ten inches.
Orientation: same. The dime was not on tilt.
The Whites battery yielded: it was really tough for the Whites battery to get the dime. The whites battery would not produce a signal from one direction. Just on the edge of detection, what I wanted. The other direction produced a very soft signal. With this battery, I would have to be listening very, very carefully, be swinging slowly and be swinging in the right direction to find this dime without first knowing where it was, with these settings. Putting the rough GEB to 12 o'clock made the signal turn into a soft repeatable that wouldn't easily be missed.
The Reidman battery yielded: to my great satisfaction, the dime produced a very soft, repeatable signal in both directions. The direction that the whites battery would hit on was slightly, slightly stronger, and the direction the whites battery wouldn't hit on would now hit. Success! I changed back to the whites, back the reidman, and so on about five more times just to make sure. As with the Whites, putting the rough GEB to 12 o'clock with the reidman made the signal soft and repeatable, and hard to miss.
So, I have concluded pretty much the obvious: it's going to be the very, very deep ones on the edge of detection that the reidman will get and the whites will miss. People that are after the deep silver, that just barely give squeaks of a signal, should consider getting this battery. I postulate that the difference will be more noticeable when a true mono coil is used, and I also bet the difference will be larger in straight pulse mode, or at least when the GEB isn't set to the extreme low. I'm sure Reg could shed more light on this, but my argument is simple: the depth increase you get is a percentage of the nominal depth you had. More nominal depth, more increase in depth. Maybe I'm just crazy. Also, according to Reidman himself, the battery needs to be run down and charged up at least 5 times to get the most out of it. I have done this.
Take care and happy hunting,
Scallops

TDI - Shooting for silver (5 replies)
As some of you regulars to this forum may know, I've been stating that I recently started using my TDI pro on land to hunt for silver items. After a few hunts with my bad pin pointer and digger, it was clear to me that the TDI could hit home runs hunting for high conductors on land. In fact, I was so confident in the detector's ability to find coins and silver jewelry that I spent over 400 dollars on the reidman battery, a bullseye trx pinpointer and a predator tools model 25 raven shovel. I got geared for some serious land hunting! Will finding silver ever pay for the 400 dollars? It would take a very long time with silver alone, very long indeed. But let's not forget the absurd amounts of clad I'm pulling along the way. Here are the pictures of the silver I have dug which is so far the result of my assault on elementary schools and local parks. People, these are places which are open to the public and are hunted regularly. I know they are hunted regularly because everything I have found has been 4 inches or deeper, very few surface finds. The other buzzards think they aren't missing anything that deep. WRONG! SUCKERS! Feast your eyes on the loot:
Not pictured are two more silver rings, a silver hoop earring, over 100 dollars in clad, plenty of wheat pennies and random assorted tokens.

Do you guys know how to "cheat" using the GB control? (no replies)
This will work great in grounds of low to mid minerals. Before I get started with the early discoveries we made while field testing I promised myself I would never try to explain the TDI to anyone. Thank God for Reg. How can you make the ground balance more responsive to silver and other high conductors if your ground balances lets say at six or less? Waiting your answer Class.

First ever TDI beach hunt (1 reply)
Well, just got back from vacation to Holden Beach NC with my TDI SL.
Had a great time detecting and found a few things and lots of money and beer caps.
Wasn't expecting a lot of gold because this is a family beach and doesn't allow parties on the beach like Myrtle. But dug some deep coins and lead in the wet salt sand. Very stable in this environment.
One tip though, when swinging try not to raise the coil at the end of your swing or the machine will false. Other than that ran super smooth, gain max, pulse 10 and ground balance off. Amazing.
I actually got to where I could tell the sound of a bobby pin. Yes there is a different sound to it.

TDI Pro gets a nice one (4 replies)
After hunting silver on land with the TDI pro for about the last 6 weeks and having tons of success, I got the itch to go for gold again at the beach. All year our beaches have been sanded in and finds have been so little, my regular competition hardly even hunts anymore. Guys I saw last year at least twice a week I've seen maybe twice the entire year. None of them hunt with deep machines, mostly excals, AT pros and I think one has an MXT. One flip flops between a CTX and an excal. One of them is a funny guy, whenever he sees me he points to my detector and says "it's alright" in depth. I challenge him to a depth test every time, he laughs and changes the subject. The point is, I'm the only one around (that I know of) that uses a PI and has a shot at rings over a foot deep. Well, even I was finding little on the beaches this year. But for some reason, I didn't have the bad gold itch that I usually get when I go on a dry spell. This is what made me try silver hunting on land. After lots of silver, I got the gold itch. Low tide was at 1:40 AM, which is another reason why I haven't been hunting the beaches (low tide is at the worst time), but I decided to go for it. I went to my favorite beach, the one that has always come through for me when I'm in dire need of a gold fix. This beach gave me my first gold ring on the first day of 2014, my best gold ring on Halloween of 2014, my mother's favorite gold ring on new year's eve of 2014 and a couple nice ones in between, including a Furrer-Jacot from Switzerland. The hunt started slow and it seemed like nothing had changed. Lots of deep bottle caps and a couple of coins. I hunted the south side of the pier and gridded almost that entire half of the beach, because that is the side that has historically produced. This time, nothing. Then I remembered not long before I hunted for silver, I got a deep copper ring on the north side of the pier. I decided to try the north side, but I was tired by that point so I did a less thorough pattern, more like just a survey pattern. Then I got a deep high tone, maybe the fiftieth one that night, and out popped the beauty! It was well past a foot deep and out of the range of any VLF, which was satisfying.
It also exemplifies why the TDI pro is the perfect detector for me: hunt deep gold at the beach, hunt silver on land. The TDI pro is a killer at both these roles, and there isn't a detector in existence that can do both roles at the same time better than the TDI, that I know of.

7 different tones? (5 replies)
From the reading I have completed so far, I thought the Whites TDI SL had basically two tones. High tones for low conductors and low tones for high conductors? I have watched videos of the machine and never heard any variance in "tone" besides what I just mentioned. Can anyone confirm this? Does a quarter give a different low tone than a IH penny? Does a nickel give a different high tone than a big honking gold ring?

Coil choice for the beach (3 replies)
New TDI user, machine has the 12" dual field coil on it.....main beach I hunt is large with some iron trash, I mainly jewelry hunt, I'd prefer not to be bothered with the small stuff so my thoughts are to get a mono coil. I've tried looking in the forums using "search" but haven't found enough info to make up my mind on which type/size of coil to purchase...or if I need to buy one. Any guidance from the TDI beach hunters out there?

A strange discovery I made during testing (4 replies)
For those of you who go back to TR machines before motion disc. I found something you can try on in ground targets. Not reverse discrimination but reverse tones with the TDI. Try this but remember its not 100% accurate. Turn on GB ID, set to all. GB your machine. If you have a test garden with high and low conductors and a nail even better. Now detect the target then quickly place the coil over the center of the signal. If the original tone was high and it changes to low or vice versa while you hold the detector motionless that is a good sign. If nothing happens or the tone fades out may be iron. Give it a whirl.

Fantastic 3AM Ring Haul - TDI pro gets honking 18k (4 replies)
I went back to the same beach that gave me 14k with 3 small diamonds (see my other post). This beach has always come through for me. After I found that 14k it dawned on me more and more how many deep bottle caps I found that night, and how all of them were way out of range of any VLF, and so was the ring. It occurred to me that being the only PI user (that I know of) in my area, the beach would be mine for the taking for the foreseeable future, at least until enough sand washes out to bring targets back into VLF range. That was Monday. During the two days after I went to another beach and a dried lake bed and got totally skunked both times with not even a junker ring. The lake bed had ridiculous amounts of pull tabs. I did a 50 square foot area and got over 100 of them. Heartbreaking. It was a real stinger because I spent 20 dollars between gas and the entrance fee to do that hunt. Ouch! The first beach where I got the 14k on Monday came back into my mind. Would it come through for me a second time? The thought of a second gold in one week nagged at me. So again I did the zombie tide - 3AM - at my favorite beach. My very first target was an insanely deep tungsten ring.In the 18 inch range. So deep the hole was taking my entire T REX scoop and my left leg past my achilles tendon. VLFs can't dream of a find that deep, at least not without some honking coil. Now, most people hate finding tungsten, but this one actually made me happy because of how deep it was and how similar tungsten and gold rings act in the tides. I knew that if there was a tungsten ring lying around that deep, the possibility of gold was increased. I kept going, working the south side of the pier, the side that has traditionally produced the best finds. I got a second tungsten ring! Wow! As deep as the first! This coming off a beach that everyone else gave up hunting, already a double ring day! Then I spotted a phone lying on top of the sand, someone had lost it at high tide. I rushed to get it under some fresh water, and took it apart and rinsed it again when I got home. I didn't have distilled water, but I didn't think it's chances were good to begin with. It's fried, oh well. It is a Samsung Galaxy Note 3 and it retails for almost 500 dollars. Could have been a good score or maybe a return if it still worked.
I kept doing my grid pattern in straight pulse mode and digging the deep, round tones. After the two tungsten rings, some really deep bottle caps. Some shallow bottle caps and pull tabs mixed in and a couple of coins. A junk bracelet at about a foot. Then I got a deep signal that I was 100% sure was a coin that was slightly on tilt. I knew it wasn't a nickel, those have a much more snappy response. I believed it was a deep, tilted penny because the signal was fatter in one direction and skinnier in another, too big to be a dime, too small to be a quarter. It just felt like a penny signal. Then I got to around the 12 - 14 inch range and realized a penny on tilt would not be detected this deep (coins on tilt have reduced depth of detection) and I still didn't have the target out. I kept digging, maybe one or two more scoops thinking now it was a bottle cap on tilt. Well, when I finally got it out, MAN WAS I WRONG!!! I had just found my heaviest ring ever - a honker 18k men's band that weighs in at 13 grams - that is almost 10 grams of pure gold and the entire weight of the ring is nearly half an ounce! I couldn't believe it! It was one of those finds where you see the glint of gold and have to pause for a minute because you know what's about to come into your hands. I bounced it in my hand and felt the weight, just incredible density. The only thing I was right about was that it must have been on tilt, because I can detect this ring in air with the coil raised almost to my knee, and it was in the 14 inch range in the sand. By the way, I use my 11 inch long T REX scoop to make these measurements. 14 inches is out of VLF range even if the ring hadn't been on tilt, so this was a very, very satisfying find.
Needless to say, this beach came through for me again, and this will probably be my find of the year, unless I get a real dazzler with decent weight and a nice stone. We will see, but I'm really happy with this find.
Here is a picture of all the loot, along with my bearded dragon getting some sun!

Reg - Coil cable (2 replies)
Probably a mute point Reg, but does coil cable length play any kind of role in battery power consumption? I know we're talking milivolts and miliamps with detectors, but in my electrical training days of high school many many years ago, we learned that as wire length increased, resistance increased which created heat and increased amperage draw. Now i know my coil cable does not get hot, but, is it possible that a shorter coil cable could improve battery life to a measureable amount?

First serious land hunt with the TDI Pro in high conductivity. (6 replies)
I took my TDI Pro out to a old park that I've hit with the AT-Pro, CTX3030, and the XP Deus. Certain sections of the park are heavily nail infested from the victory gardens and chicken coops during the World wars. I've pulled silvers and coppers from these areas with all machines, but I was very curious to see what the TDI Pro with the 12" OZ mono coil could do in the iron.
This is the results from 2 days hunts.

![s227.photobucket.com]( "s227.photobucket.com")
Kids gold plated junk ring with 4 fake diamond chips. High tone on surface in mud.
Old Copper Snake ring. Low tone, 3 scoops deep with STAVR MONSTRIK-9 scoop.
All in all, I'd say high tone mode works really good. Not pictured was the nails and larger iron that fooled me.
GL & HH I'm heading back there tomorrow again, its a BIG park.
This is the results from 2 days hunts.
From top to bottom, left to right;
Silver 1918 George V "Fishscale" 5 cent piece
Bronze Victorian ladies pin
Silver 1910 Edward VII 10 cents
Silver 1918 George V 10 cents
Bronze Boy Scout Pin, has a clip on the back for buttonhole fastening.
1929 George V Nickel, which surprised me, it being 100% nickel metal. It still warbled on the outer edge of the coil.
1906 Indian Head Penny
1940 George VI Penny
1916 George V Large Cent

help with coil selection / pinpointing with the TDI (1 reply)
I have concerns about pinpointing with the standard 12" coil. Seems as though many of the posts I have been reading on FM and other sites that it is somewhat difficult to pinpoint the target. I know one great tip is to decrease gain but I want to be extremely accurate in pinpointing and wonder if there are much more accurate / smaller coil (s) that I can utilize in the public parks that I hunt. Thanks - Jim
