I have a TDI SL coming in today. I know most people want to detect for small gold. In my bad soil I want to detect silver coins that my CTX3030 can't reach. I'm a long way from the beach and probably long way from gold. That leaves coins and relics. I've heard that larger coils tend to ignore small trash which sounds good for a coin hunter. I know that if you raise the delay that this helps but with a loss of depth. A 12" dual field and 7.5" dual field are coming with the machine. What could I get that would be better suited for detecting coins?

Have been reading past treads from Steve H., Reg Snift, and others concerning modification that could be added to the TDI, TDI PRO, and TDI SL. One was a Li ion battery pack to up the voltage. I can do that. Another was to change a couple caps (c20 and c21) to .22 mf and change a couple op amps. Sounded like Reg would do some for a price. Then sounded like Reid Mann in Virginia would do them. Then the VP from Whites came on the forum asking for feedback. I forget his name but think he just retired , anyway, his final answer sounded like he would have this mod. incorporated into the new TDI SL future production. This was a year or two back. Now my question, Do you know if this mod. has been installed in the new TDI SL that fedex is supposed to deliver to me tomorrow? If not since I'm a retired electronic tech. I could install myself if Reg had given a little more information. If no one has or are willing to give out, do you know anyone that installs the mod. for a price? Thanks, Joe

Has anyone else that’s using the supplied hip/chest mount pouch had issues with it splitting. My first one started within days and Whites sent me a replacement. First time out yesterday with the new one and it’s spliitting by the netting. Its not the design or the stitching, it’s the poor quality material used. They really should’ve used terylene or something stronger

I enjoy the DetectorComparison videos, he does a good job. Some not new but solid tips at the end of the video.

i ordered some 3.7v battery's my question is the Balance boards .. will this board work fine for me https://www.banggood.com/3Pcs-4S-30A-14_8V-Li-ion-Lithium-18650-Battery-BMS-Packs-PCB-Protection-Board-Balance-p-1191042.html?gmcCountry=US&currency=USD&createTmp=1&gclid=EAIaIQobChMIkP3vjbbD4AIVwdHACh0vjQInEAEYASABEgJZ_vD_BwE&cur_warehouse=CN also these are the batterys im getting 18650 battery Rechargeable High Drain Battery Voltage: 3.7V Storage Voltage: 3.7-3.9V Charging Cut-off Voltage: 4.2V Discharge Cut-off Voltage: 2.5V Capacity: 4000mAh Size: 18.0*65.0mm Weight: 50g Battery top: Flat top

...is that you can chest or hip mount the control box using the included pouch. The BeachHunter TDI is already the lightest weight waterproof ground balancing pulse induction (GBPI) detector on the market at 5.2 lbs. It is also the only GBPI model that comes ready to hip or chest mount. If you chest or hip mount the control box all you are swinging is the rod and coil at about 2 lbs. Nice! Note that the coil on the BeachHunter TDI is hardwired to the control box. Use care not to bend and stress the connection point to the control box as it could lead to premature failure of the coil cable.

Published on Jan 18, 2019 by White's Electronics, Inc. Can your P.I. detector discriminate iron? If you have a TDI the answer is yes it can!

Tom, I have a brand new (3 spoke centre mount) 10" coil hand built by Eric Foster that I would like to have installed onto my TDI Beach Hunter. Is this something I could have White's do for me to maintain warranty? If so, could you PM me on cost and anything else I should consider. I find the 12" Dual Field just a bit too big for water hunting. Thanks for any help, Tony

Daniel Teague Published on Dec 5, 2018 Some of you guys were curious as to the tone differences between a Minelab GPX and Whites TDI. This is the GPX 4800 and TDI Beachhunter and a little bit of why I like the GPX better when it comes to relic and beach hunting.

So my brother who has been detecting for 20 years has only recovered 1 gold ring and that ended up in a museum in England. I promised him if he used the new White's TDI "DEEP" Beach Hunter the whole time on our hunt that he'd find more than 1 gold ring. Not only did he do that, but he also recovered the best ring of the trip, this monster Emerald, diamond and yellow gold beauty. Hats off to you Travis for not giving up on those deep signals. Folks, the TDI Beach Hunter is a Pulse Induction detector and it goes much deeper than standard machines. Plus it runs smoother than most in salt water and is simple to use...just turn it on, set the knobs and go. One of the cool features of the TDI beach Hunter is the Tone Identification system that allows you to decide if you want to dig the High Tone Only, which gives you a greater chance of gold and platinum rings, or the Low Tones which are usually most coins. This feature alone saves time as you will end up digging DEEP. One other thing to have, a good Deep Beach Scoop.

Silver or pure gold is low ton in TDI beach huner, but other low ton railways. Beach Hunter is wrong with TDI Pro? TDI Pro is not low ton.How do you set up the others?

Interesting to recover so many religious medals on 1 trip but "Faith" was on our side. The best of the 5 is the yellow gold with diamonds in the middle, but I have to give credit to my brother as he saved that one. The sterling pieces are very nice as is the other ones of lesser metal, but with the same powerful meaning. The TDI Beach Hunter did its job and I have faith this machine will do well for many. Steve, If you feel this post needs to be in the Jewelry Forum, I understand. Some folks do not feel religion wear is jewelry..so I walk softly.

I may have an opportunity to buy a Whites TDI SL with two rechargeable NINH batteries, one AA battery pack, jimmy sierra elliptical dual field mono coil, miner john elliptical waterproof coil, 2 large TDI round open coils, and a Whites padded carry bag/case. Would it be worth buying since I have an Equinox 800 and a Teknetics G2? He's asking $750.

Just thought I'd post this............. I now run a 14.8v pack (4 x 18650 cells in series) which gives me a 7 hour run time. My previous version used loose cells in a holder but I wasn't happy with that. I made up a battery lead that connects directly to the battery compartment contacts with small brass "screw terminal" connectors soldered with 22AWG wire. A bit fiddly to hook up (long and narrow screw driver needed to tighten the two terminal screws) but very secure and + - leads well apart to avoid a short. I may put in place a rubber divider that further separates the +- battery contacts but the screw connectors are quite secure. The battery pack fits in snugly and does not move around at all. I deliberately made the wire lead long enough so the battery can be unplugged with the excess lead bundled inside the battery compartment. Tony

Normally I am not one to watch people taking something out of a box, but these folks do a good job of filming every little part and piece of the Beachhunter TDI....

I thought I'd copy this from my other thread which was buried down on the second page.......is this okay Steve as I don't want to duplicate if unnecessary? "Just got back from the beach....in one word.........awesome. Some observations; It is the deepest detector I have ever used on the beach (in the past 25 years) by running the higher voltage pack. It is the first time I have ever detected (with any detector, including the Minelab PI's) my gold wedding ring at a measured/buried 18" deep. The US nickel can be heard at 16" in buried wet sand...but with GB OFF. With GB ON it drops to 12"-13" ! My machine is much deeper with GB OFF across all targets.....the rock solid threshold with GB OFF is unbelievable with no loss of sensitivity. Even with the coil swept through shallow salt water at max gain and 10us......it is so smooth. I don't know how White's have done it....maybe a new batch of the latest flux capacitors...... I tried with GB on but in clean white sand, there was no perfect GB....it was close but just a slight positive signal as the coil was lowered to the ground...but the depth loss was significant with GB on and slight falsing with higher GAIN. None of this is a problem with GB OFF." Tony PS.......on the real deepies (edge of detectability), there is often a one, two and three way signal but not a four way signal if swept from left,right and up and down.

Well I sat down and re-visited the 4 x 18650 batteries for the TDI Beach Hunter and managed a successful battery boost.....It's a snug fit but went in better than expected. Now someone probably has another version but here is my Ghetto version ! I needed to remove most of the White's battery holder to reduce the overall height otherwise the 18650 holder would sit on the floor of the White's holder. All that's really needed is the end part to make the electrical contact. The two outer batteries are quite secure inside the detector as they snug up against the battery compartment housing. 1. Cut down AA White's battery holder 2. Trimmed down 18650 battery holder 3. Removal of two small plastic tabs from the "roof" of the detector's battery compartment (easy and very neat) 4. Bit of hot glue to bring the two holders together but doesn't need to be super strong. 5. Soldering of 18650 leads to contacts on the White's battery holder And for the record.........the depth increase on my gold ring is a solid 1.5" to 2" over the standard 12v pack. Range has jumped from 14" to 16" with GB off and everything else at max.
