  1. Just a short note on Joe’s “shorty” AQ battery. It fits well under the cuff and balance was not noticeably effected from the lighter than stock battery. Run time for me in “tone mode” was 6 hours 20 minutes. It is my understanding that in all metal it is approximately one hour less. The M12 (CTX) phones connector was a welcomed change and the power cable with a small loop and ninety degree connector also worked well. Get one of his battery set ups and avoid changing batteries in mid hunt, while they are available. I believe he has other set ups with even longer run times. Knocked it out of the
  2. I even bought the universal charger with 4 USB ports from Minelab and NEVER used anything but this to charge the machine. I have used it three times, I plugged it in the first night and I though it charged it fine. I had not been paying attention and today the fourth time I took it out it flashed BF. Left charging all day and green light even stays on indicating that it is fully charged but when I turn it on its flashing the battery meaning its less than 5% charged. very frustrating, going to try another charger that has greater than 2 amps. Thanks for any comments / feedb
  3. Being a Fisher Repair center for the South East Back In Los Banos era I met and talked with some very incredible people from Jim L. President of Fisher Research Labs To a few legendary Relic hunters of that time in the south east that needed help Repairs inspiration or a pointer in the right direction...... To this day I still have my Repair manuals and updates some the best electronics ever conceived Mike asked me not to sell or give out the technology .....I have always kept my word. I would have 3D printer or a jig and router and a one inch extension of the battery lid on
  4. After a busy week, doing an effort between heavy rain interruptions, I finally finished this work! Thanks for all people involved in this project for their knowledge shared... Underwater test next week(I hope)
  5. Click or double click any photos in this article for high resolution versions. I bought this 4 x 26650 battery holder on eBay after quite a bit of Google work. They are a surprisingly rare item. It comes with sleeves that can use 4 x 18650 batteries also. It ran me $29.65 delivered including shipping and tax. I ordered it on June 25th and it arrived from China on July 14th. The holder delivers 16.8V via a DC adapter plug or 5V via a USB outlet. It has a thin oring on the lid for an IP67 seal. I also ordered an IP67 M8 4 pole 16.4 foot female to pigtail cable from Automation Direct fo
  6. I hope this topic hasn't already been covered and I'm not writing it in the wrong place. Recently, based on my lack of knowledge in this sector, I have however noticed large differences in actual life, not only because of battery chemistry ... I mean something about the use of power itself in using the tool. Thinking of a mobile phone, the standby time is merely relative to the battery capacity, as is the duration in call or video call, much less long ... So every time a detector is used in an area where there are several signals and we are busy digging or at least hearing many of them
  7. Joe, are you using a bms module inside the 4s1p tube?I hope not because.... I actually don't know if I'm correct but seems to be the easier combination for a self balanced recharge without the need of multiple solder and little cables around cells, not to mention the module itself presence inside the pod... I'm developing a similar pack for the Tdi and can be the base for the future of my dreamed AQ...
  8. 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.
  9. 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.
  10. I just finished the next iteration of my 9V to AAA battery adapter for my Pro-Pointer AT (Carrot). You can read about it in my blog post that will be uploaded soon (see my profile for the link, if you're that curious), but most of the "juice" is in the pictures. In case you're wondering (or you don't recall my prior blog posts about this building process😞 1. Yes, waterproof integrity is maintained.2. Yes, the performance when using this adapter is identical to using a regular 9V battery.3. Yes, this can still use a regular 9V battery.4. Yes, runtime is less than with a regular 9V bat
  11. I've successfully removed 9V batteries from my Garrett Carrot (which now uses AAA batteries) and I've started on the process and getting rid of 9V batteries in my Fisher F2. I've taken the approach if trying to use a single battery to power the F2. A while back, I read from somewhere that the F2 ran off two 9v batteries running in parallel. However, this means that if I use a single battery for the F2, it should work (assuming the single battery has the ability to provide the necessary current). But when I try to use this set up, my battery gets warm. I eventually realized that the Fishe
  12. Got sick of buying 9v batteries for my Profind pp. Blackube just came out with rechargeable 9v lithium batters that have the same voltage as an alkaline. A little pricey at $25 for 2 but the PP no longer falses out when put on it's side then turned back up. This used to drive me crazy. Batteries put out near full power until they run out instead of fading in power like alkalines do. IMO worth the few extra bucks.
  13. Lost ours out in the sticks lol. Where to get a replacement charging cable for the Minelab WM-12? Thanks.
  14. One my beefs with the Kruzer is the battery life in the Multi Kruzer especially in low frequencies even though you get close to a full day run time it is nice not have to recharge every time your done. I went and got the external battery for it which balances the machine even better but also noticed they use the same battery pack as the Garrett AT series detectors. I think I will use my RnB litho battery on it to see how long it lasts and see if the battery life indicator shows battery life (something the standard rechargeable lithium batteries don't do). Should work as the volt
  15. 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 +- batt
  16. Did a run today but tossed in the RnB Power Pack Plus from my AT Pro into my Multi Kruzer's external back up battery case with label side up and it works perfectly. So for those looking for an extra rechargeable battery for their Kruzer series or Amphibio the RnB is a good choice. Has a really long run time and should save beating up the internal battery that comes with the machines.
  17. 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 teste
  18. Just wondering If anyone has used a External Power Bank. 1. What kind did you buy and what size mAh? 2. If so how did you attach it to the detector and where? 3. How did it work if you just used it for charging both the head set and the detector?❓
  19. Hello all I'm just wondering if anybody has taken a GPZ 7000 battery and replaced the (I'm guessing 18650??) cells? I have two battery packs both out of warranty and have some time on my hands at home due to bloody Rona. Stay safe Cheers BBB
  20. This morning I plugged the charger into the deus and my WS4 headphones were dead, they would come on for a split second when first plugging them in but that was it and the battery indicator was completely nonexistent, I’d run them down last time out and forgot to charge them and they sat uncharged for probably a couple months my bad I know better. Couple years ago the lithium battery in my Cordless drill stopped taking a charge and after researching I found with my drill anyway the batteries had a habit of doing that and someone had found a fix that sometimes worked, trick was to rapidly plug
  21. 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
  22. Just wondering if anyone has tried these? Sound and look like they are amazing and can be used with other devices that are charged by usb.
  23. Hi all newbie on this forum from the UK anyone know which battery charger fits the Nautilus 2ba and what is the full electric specification for this voltage etc? just got a very nice 2ba machine near mint condition any info would be good thanks.
  24. Well the Northeast has for the most part been blistering cold. Pretty much made me decide to follow new pursuits during the winter, as well as hanging up the NOX. Didn't give much thought until now about keeping battery for the Nox, headset and adaptor. Was kind of thinking every two or three months until spring. Do you people (gender Neutral) have any different thoughts on this? PROP
