  1. It seems requirements around shipping or flying with Lithium Ion batteries are increasing. Either intentionally or by mistake. See this post: “Hi forum, I’m desperately looking for a good condition LI battery full size for my GPX 5000. I travelled half way across the world to do some winter detecting Arizona way and my airline refused my battery at check in; both hold and carry on were not permitted. Any one got a battery for sale this would help me out massively. Don't want to buy a new one as I’m only here for a month and can re-unite with mine back home.” Fisher Research was originally designing the new Fisher Impulse AQ with a Li-Ion battery pack but recently switched to NiMH instead for the external battery pack. It may be this decision was prompted by issues like this. It does not bode well for those traveling with large batteries in particular. On my trip to England my having a large Anker USB charger pack in my carry-on got me shunted into a separate full security check. There is a lot more scrutiny on international flights. Just a heads up for anyone traveling with a GPX detector. Integrated batteries like on a Equinox should pose no issues.
  2. The Impulse AQ was said to have Li-Ion batteries up until recently, and is now said to be coming with a NiMH battery pack. I am guessing this is related to increasing issues surrounding the shipping and transport of Lithium Ion batteries. Especially large external batteries. See this thread.
  3. I was looking for battery tray design for my Tdi SL which would allow 4 x 18650 batteries. As luck would have it on the local Prospecting Australia website XLOOX posted a simple mod for a Whites factory battery tray. I don't know how to post links so the full description is to be found in the Prospecting Australia site. Simple cut out the guts of the tray, leaving the original battery connectors with mods on one end and a copper connector on the other. I can fit Panasonic NCR18650B cells, without nipples but with protection. They just fit snuggly. The only issue is closing the lid, you need to cut a channel under the batteries into the base of the tray to allow for this. I'll cover this with a thin carbon fibre sheet and look at using a thinner sheet for the cover also. I will also add something to secure the batteries in position. Just waiting for the postman to deliver my carbon fibre sheet before finishing my own version of XLOOX's design. What I like most is that this is simple and cheap. Must confess I am aware of many different designs, since there have been no reports of smoking Tdi Sl machines I have finally decided to give it a go. All the best, Karelian
  4. Hello, I hope everyone had a Great Christmas and Santa was good to you. I have an old Minelab GPX 5000 from 2014. I tried firing it up and of course the rechargeable batteries are as dead as a doornail. There are three (I think they are lithium) batteries that are about 2.625" long by .720" diameter. I don't want to spend the enormous money of getting a new battery pack or having Minelab replace them. I have spent most of my life as an Electronic Technician so this would be a simple replacement for me. I am almost positive that these batteries are a 1860 Lithium, but I want to make doubly sure. I would really appreciate it if I can confirm this info. The batteries in the unit are not labeled at all. Thank You.
  5. I'm thinking about getting a TDI sl and I have read about doing battery mods to achieve a higher voltage. This battery is only 12 volts but being li-ion it will maintain 12v for longer. Does anyone have any experience with this particular one? https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.amazon.com/RnB-Innovations-HP-3100-Lithium-ion-Detectors/dp/B00LXBWB6Q&ved=2ahUKEwju1Y3o3NTmAhX3GjQIHXcpAh8QFjABegQIBBAB&usg=AOvVaw0BCc0ZVlS3nhsHmuE0gszj&cshid=1577412259463
  6. What kind of batteries ya'll use? I used to buy nothing but Duracell rechargeable, then in the last year I couldn't find any. I just bought some Rayovac with a charger, but they don't seem to hold a charge. I charged them, put them in, they showed full charge as I hunted for about an hour, then the next day only see two dots on the power gauge. I recharged them hoping they needed a break in, but they did the same thing. Now I have used them for 3 days, with only two dots showing, they don't seem to be going any lower, but I don't trust them. I just did a search and found a bunch of Duracells, I might of been looking for the same charger I used to have, that died, and couldn't find it. I hate to go spend more on a different brand...I didn't notice until now, the rechargeable's are 1.2 volt, whereas the regular are 1.5 volt, would that make a difference? I don't want a battery pack, at least not a NiCad...
  7. When hooking up to charge LED is not lighting up except with feeble glow. Charger cables and contact were checked. If not lighting up bright do I assume a faulty coil battery?, how do I know? thanks
  8. This has probably been covered before but I couldn't find anything...if it has a link to the relevant post will suffice. Just wondering, if I charge my nox after being out on a search, how long can it sit before it needs to be recharged? Or should I just top it up before going out again? Thanks in advance.
  9. 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
  10. After one year of testing my old Whites, Spectra V3i works almost 4 times longer. 18650 3.7V LiPo batteries holder, from my 3D printer, is ready:
  11. Hi! after a year of snorkeling with TDI BH I concluded that I can clearly note the sensitivity goes down ones the voltage of my battery pack goes down. Other conclusion was that even at 12.6V the TDI BH is noisy underwater at maximum settings: it reacts to the waves. Thus at the moment I really prefer to have just a stabilized battery pack. For my experiment I took a couple of 21700 5aH Li-Ion cells and a dc-dc booster board. the plan is to get "one hunt" battery pack.
  12. Detector center is doing replacement batteries with longer run times for $40. https://www.detectorrepair.com/index.php/store/wm10-wm12-replacement-battery https://www.detectorrepair.com/ Detector Center 188 Oak Shade Road Alum Bank, PA 15521 Phone: 814-283-4270 Email: shop@detectorrepair.com
  13. I recently purchased these They are the proper 1.5 volt and lithium batteries. They work well in my Tesoro that tends to chew up batteries fairly quickly. Will see how they hold up. They should not fade in performance as regular Alkalines do. $20 for 4 is pretty good. Much less than the $80 I paid for my AT Pro lithium pack.
  14. Hi folks, so I've ordered myself a TDI SL and spent a few hrs on line trying to find anyone that ships the RnB innovations 14.4v battery to Australia which proved to be an impossible task. So I went on to try and find the highest capacity longest lasting AA batteries for the dry pack and came across the Kentli 1.5v 3000mWh rechargable lithium polimer batteries. I have to say it looks like a brilliant idea but some of the reviews I seen aren't all that great. Now being aware that a lot of reviews are probably BS of one kind or another I have to ask who here has heard of or tried these? The idea of getting a constant 12v in the machine is appealing. Would be good to see some of you electrical gurus out there put them to the test?
  15. Just received the Equinox Charging Essentials from Doc's Detecting. It came fully charged and the power bank seems to be a solid piece of equipment. Cost $63.45 including shipping. As soon as my local park detecting sessions drop my E600 one battery level, I'll try it out. Maybe I should also buy another charging cable before venturing to remote areas. About a month ago I also obtained Doc's cover for the 600. Both sales resulted from references to Doc's in the Equinox Handbook. Speaking of the Handbook, I have changed Park1 to the Cherrying Picking settings, Field2 to the souped up version, and Beach1 to Beach for Land. The latter nabbed me a 1952 Wheatie in a hammered park.
  16. I recharged my Nox 800 as usual 3 days ago and it took about 12H. Before it took about 4 hours in average. I did not change any items nor did I use a different socket. What came to my attention for some while is that the magnets of the charger cable became weak not holding on to the unit as they used to. I have about 100 charging cycles done in the past 7 months since I got my machine going out about 5-6 times a week. I'm curious if anyone made the same experience? I will try the other cable which came with the machine after running it flat. I usually charge after 2-3 detecting sessions (usually about 2-3 hours each session). As I have a trip to CA coming up beginning of September I don't want to take a chance getting into trouble being there. Should I have the battery replaced?
  17. Does anybody know if its possible to use a solar cell panel to run a small electric bilge pump for a small highbanker? Will it have to be in direct sunlight ? Mine is a Johnson 2200 gph bilge pump that pulls 8 amps at 12 volts What size panel will I need and what do they cost? Can I run the output straight to the water pump or do I need a controller thing? Or can I use a panel to recharge my 12 volt ,15 amp gel cell and how long will it take? Thanks. -Tom V.
  18. How many of you have had problems with the charger cable? I’ve had the 800 for 14 months now and both of my charger cables have died. Have any of you had this happened to you and were they replaced under warranty? Thanks Oscar
  19. Nice batteries can be found in used laptop battery packs. I found 6, nice batteries inside a HP laptop battery pack. All test good and can provide some nice project batteries. Some of the best on the market can be found in laptop batteries. A trip to the local computer repair shop can usually find some nice discarded batteries cheap.

  20. I just ordered one of these as an experiment. In theory I can put regular AA batteries or rechargeable batteries in this power pack, and use it to run the Equinox as an external battery pack in case the internal battery goes dead. The question of course is how long will it power the Equinox depending on the batteries used? I always have a ton of AA batteries around, both alkaline and rechargeable, so this seems like a cheap experiment. Report back later.

  21. Why do so many metal detecting companies use 9V batteries for their products? What is this, 1979? 9V batteries aren't even used exclusively in smoke detectors anymore. I want a new pinpointer but I'm absolutely appalled that so many of them use 9V batteries. Is there a logical or engineering reason for this?
  22. I was charging stuff off my truck a few years ago, and at one point was not paying attention and had the heater turned on in the truck with while I had the key on but motor off. A panic situation developed when my truck was dead in an out of the way spot, but I got lucky and was able to round up a jump. Still, it spooked me and I have been taking a spare 12V battery with me in my truck on my trips by myself to remote places, especially when out of cell range. Driving around with a spare wet battery is a pain for various reasons, so I have been eyeballing an alternative for over a year now. My preferred option was a bit expensive for my taste, but my recent sale of extra detectors and such left me with some funds, so I pulled the trigger. NOCO Genius Boost Pro GB150 4000 Amp 12V Lithium Jump Starter This baby is overkill I am sure, but I kept worrying about cheaper units. When dealing with emergency gear I am not sure cheaper is better! Anyway, this thing will jump start almost anything, can charge detectors, etc., has a built in flashlight and 12V meter, and only weighs 6 lb 3.3 oz or 282 grams on my postal scales. On one of my upcoming outings I will find out how many times I can charge my GPZ 7000 off of it and report back, but that may be awhile. Specification Sheet
