  1. The hot glue is used quite a bit to keep trim pots from moving as well as keeping connectors from working loose. You will probably see more variations between machines because the components have a tolerance +/- and lower grade components will have a higher percentage.

    Newer models should be better than old if the manufacturer updates the pcb and any chips with improved circuits.

  2. I have one as the pinpointer. Very well built but lacks sensitivity to tiny targets. As a diving detector it isn't very deep. Comparing it to a Seahunter with same size 8" coil the Seahunter is way deeper. However it would be a really good choice for snorkeling since your probably not going to dig deep anyways.

    There is no discrimination on it so you will be digging all with it.

  3. I change coils on my machines quite a bit, always hated the way velcro twists around. I also lost a couple of coils from Nel and Mars as their connectors aren't all that sturdy and the heavy cable wire likes to bunch up which eventually breaks the connections inside the strain reliefs. Something for you guys to think about when winding the cables on the shafts.

    I came up with a cleat and cast a bunch out of urethane so they are gentle on the wires. So far cleats are working really well for me. I will be shipping a batch out on monday but figured I would post what they look like for those that may want something better. Not sure how well they will work on 3 section shaft systems like the 900 and Manticore have. I have to check that out.

    Used my initials for the name to add that touch of cheesiness 🙂

    Questions, comments etc all welcome.

    Thanks

    Nice to see that alternative Li cell fitted in OK, good work.

    Keep the old cell, the protection PCB is re-purposable. Any single unprotected Li cell could be wired up to it, to create a protected one.

    [ As the Geotech1 Forum is currently accessible, I will promote a thread on it about E-cigarettes/Vape devices, especially disposable types. Useable, fully-rechargeable Li cells can be salvaged from these heavily-littered items.]

    Thats a really good idea, never thought about the vapes, I usually dig them and toss in rubbish to get them out of the parks.

    I did save the battery as it still works and thought I might jinx myself if I tossed it. New battery definitely lasting a lot longer.

    Is that the Nel Superfly? I bought that coil once from Ukraine, it never arrived, I'm not all that bothered as I bought it for the Simplex which I never use.  Ebay gave me my money back so no big deal, but I'd still like to get that coil for my Gold Bug Pro.

    Was going to buy the Cors Butterfly directly from Ukrain and my gut said no.......

    Both companies suppsed to be starting back up this spring.

    As deep as possible.  Remember...9 or 10 inches in the air does not equate to the same in the ground. It will be a lot less, especially in mineralized ground. My Buddy's non neutered F75 can detect every signal in my test garden and even IDs the deepest one correct.  My neutered F75 doesn't make a peep on 3 of the same targets. It wouldn't be any different "in the wild" either.  

    That is true. I use all metal mode to try to pick out stuff from mixed targets like a chunk of rust and maybe, just maybe something else so ID's don't really need to be all that accurate. It also helps when there are hot rocks around as true all metal you get a null on negative rocks that can change target responses on targets nearby making them unstable. Very hard to hear a negative hot rock in any discrimination mode. Still an effective way to hunt by size and depth in moderate and low trash areas.

    Have any of you used non motion detecting? Like the Bandido's or Outlaw? Could see that working well unless there is a lot of trash.

  7. How deep do you really need to go? I often hunt with the Mulit Kruzer in all metal, most the time I just get a -- but still hear a target of some sorts. I will toss it into 2 tone or deep to check the target more if is sounds like a good size target. Good way to scout out for deeper targets in less trashy areas. F5 with it's low frequency should run pretty smooth in tougher grounds. Not sure how much a bigger coil will go or if it's worth the $$. I have better success with smaller coils than slugging large coils around but really depends on the grounds.

    Have a Kruzer coming. Will be upgrading the battery with this. Will have to save the connection off old battery to use on the new battery.

    Might get a few more hours out of the machine upgrading to a 4000 MAh battery vs the 3700 MHh baterry that machine comes with. The dimensions are just slightly different but should easily work.

    Funny Joe sent me a message on this battery and I had just ordered one earlier! Didn't see that one before on ebay.

    Not sure if you took yours apart yet but they don't have threaded inserts so be careful not to strip the plastic.

    Popping it apart is easy but do it evenly as there is a pin rail connecting the display/control board to the circuits that are mounted on back half. Old battery is double face taped and has a rubber strap holding it in place.. There is also a thermal sensor you need to tape onto the new battery.

  9. I believe the F5 is a little shy on depth compared to F75 and T2.

    The AT Max is a very deep machine but the only thing I don't like about it for all metal is the threshold isn't fine enough. Set at 1 it is too loud for my taste and 0 I feel like I am missing something. Alternatively I can run my Tejon in AM with pitch mode on and 2nd disc to junk check (something you can probably do well with your Vista X), or I use my Gold Racer as it has nice isat control with good tracking. Gold Racer also has imask to handle any hot rocks I run into which are common along the river near me and lake shores.

    F5 has been discontinued. I almost bought one but seems that Fisher remapped nickels up near pennies in disc modes so targets aren't in natural order. I use nickels as a break point or reference for the hight end mark of most gold jewlery. Moving that point up near coins will put me into the flip tab mark in junk.

    Not sure if the remapping effects all metal on the F5?

  10. Both Ebay and Amazon have been known to sell knockoffs. Something you don't hear about from authorized dealers. End of the day you will get better service from a small reliable dealer and often solid opinions of a machine than you will from Ebay or Amazon. Granted Ebay has quite a few dealers selling on them. Amazon beats up on merchants badly. I limit my purchasing there in particular.

    What is funny is many of the big importers will sell on Ebay, Amazon and Ali Express often with the same product but different names. Quite a bit of those products come from Alibaba.

    Wonder how many of those products will dry up if there is a conflict with China and the west?

    I’m not sure about “finally answered.” I’ve been saying that for ages. It’s just not what people want to hear. It’s like buying vanilla ice cream. There are many varieties of vanilla, and we all have our preferences, but in the end it’s all still vanilla ice cream. In my world the choice is more about whether I want to use a PI for genuine power, or settle for a VLF to deal with some discrimination issue. All VLFs are second tier detectors when it comes to raw power.

    If you genuinely care about making more finds put all your efforts into research and getting to new and hopefully better locations. That will make far more diffence than hunting that same old park the hundredth time with the latest new whiz bang toy.

    Your Exactly Right.

    As usual what we see year after year is the hype behind the latest machines and we will continue to see it as that is how marketing works.

    Unfortunately there are quite a few people who test the latest machines for free then pimp them out as the best thing ever!

    Size 904085 means the dimensions are 9.0 x 40 x 85 mm.
    "90" indicates thickness in tenth of mm, so 9.0mm thick
    "40" indicates width in mm
    "85" indicates length in mm
    So as an 'emergency measure' , you could fit a smaller cell in its place, such as a thinner one, with the same L & W, or one the correct thickness, and width, but shorter in length. Obviously a smaller cell will have a smaller capacity and correspondingly shorter runtime. I've no idea what runtimes on this machine are, so can't say how small you could go and still have a useable machine.
    Original spec is nominally 3700 mAh I believe?

    One possible candidate is 804070 size, which appears to be used in some computer gadgetry. I see they are listed on US eBay, US stockist. ( they are 2600 mAh, about 70% of the capacity of the original )

    https://www.ebay.com/itm/175146369695

    The seller of the above also has a 104080 ( 10 x 40 x 80mm ) , if you think 10mm thick could be squeezed in, it would be a good substitute, as it's 4000 mAh capacity

    https://www.ebay.com/itm/174763350067

    Thanks that makes sense. I'll open it up again and measure how much room I have inside. The thickness is a little critical as they have a rubber strap that holds it inside and there is a thermal sensor that sits on the battery so if it gets too hot the machine will automatically shut down.

    I am more inclined to just remove the internal battery and use the external pod only instead. What I have to figure out is if I remove the internal battery and there is nothing on the terminal pins will the machine see the external battery? I say that because if my external battery runs out the machine will not turn on unless I disconnect the pod from the control box and only then will it start again using the internal battery.

    My guess it might just work fine and if not maybe put a jumper across the terminals inside. Hate popping this machine apart too many times as the frame only has screws going into plastic, no threaded inserts so I need to be careful not to strip any of them out. Machine has already had a leak which was disappointing.

    Still not happy with the way Nokta discontinues a product and scrubs support for older products. What happens few years down the road with the newer machines? No matter probably my last Nokta products, time for couple of band-aids and move on.
