Always takes time to learn a new machine. Try to keep it simple and 3-4 tones might help.

Updated door. Made some adjustments as ABS likes to shrink when printed.

I found my first silver with the AT Pro. If I were told it’s the only machine I could ever use I wouldn’t be too sad about it. My only comment on obsolescence would be that the price should reflect that competition has now entered the marketplace. But as single frequency metal detectors go, it’s as good as it gets really. 

I found a Reale and Trime with mine in the past.

Have you used the 6.5x9 concentric on it? I had the 9x12 which worked pretty well around iron but was bit heavy.

How much do those robots cost? Thinking if you can't beat them then join them!

3d printed parts can be strong enough but depends on the design of the part, filament used and printer setup and settings. Advanced materials such as glass and carbon filled offer much more strength basic materials.

Duplicating a part that was injection molded with thin walls with a fdm will not have the same strength as the parts are formed differently.

CNC machining of parts is very costly and designs can have limitations.

FDM has a good advjantage over cnc machined parts and injection molded parts when parts have thick bodies. CNC part will be heavy and an injection molded part will have suck back and ejector pin marks. Also injection molded parts with thick surfaces also suffer from fissures where the plastic doesn't cool evenly or flow evenly causing weak spots.

FDM has the advantage of using infill patterns where you maintain strength and reduce material and use.

Consider in the case of use for metal detectors with making a coil housing.

Injection molded part would work but be expensive in tooling. Where coil ears are you risk suck back causing a weak spot.

CNC part the cost would be through the roof.

Vacuum formed (most common) is the most cost effective but the entire underside indcluding support ribs would need to be filled with epoxy to make it rigid to avoid knock sensitivity and then will be heavy.

For short production a coil housing done with fdm will not necessarily have the suface quality of the other processes without post processing ie sanding or acetone vapor baths but you can take the solid support ribs and use an infill and internally add support structures to make it rigid with less weight.

The part design needs to be adjusted for the process and material being used.

Additive manufacturing and CNC have their place but not in a mass production demand.

It does look a nice build quality detector, and at 30kHz it should be decent on nuggets.  I'd be surprised if it's 40 to 50cm air test depth is anything like that in the ground though, it comes standard with an 11" coil.

The Gold Gain has both gain and sensitivity and similar price. I think the GG would be the better machine in that regard. Again... unless they have a machine under 10khz or have concentric coil options, hunting around small iron can mask you out as it would with any other machine with vdi or not. High frequency machines are nice but depending on the area and type of hunting your doing can be very counter productive.

We'll there's this 🤔 

I want one! Couldn't come up with a better way to block isles in the super market or traffic than one of those.

If a coin is in gravel it is usually scratched up anyways. I usually make a larger hole around and work the gravel loose to get them free.

I have an old sleeping bag that smells like vomit....... should help deter theft 🙂

Thought Vista X is a dual discrim much like the Tejon. Not sure what they would need to convert to digital since it doesn't have a VDI.

Different style of hunting. Analog machines take time to learn the machine being used. Not all are the same or have same nuances. They can be difficult in high trash areas especially around can slaw.

As for Deeptech they really need to have some concentric coil options for their lineup. All are above 10khz which can be a big problem around nails and sheet metal like can bits.

Gold Gain looks like it could be a formidable jewelry hunter with that super six coil in parks and tot lots.

Onyx around the rim? It is purdy.

What do you mean break? When hunting in all metal I listen for a rise in tone and keep base hum at a minimum. If the hum gradually rises or drops off I know I am out of ground balance.  I can often find faint targets that may not even have an ID and are just on the fringe of detection for the machine/coil combination.

Useful in moderate and low trash areas for deeper searching.

We are able to post 3d files here on the forum. Will be easier for users to access files that relate to the detecting industry.

I just posted final files for the Cibola/Vaquero battery door that I made. Will be posting more models as I make them.

Not a good idea to post files that others make without permission (duh).

Attached is the final files for the Cibola/Vaquero battery door. Pic shows test print in white PLA that I used to check fit from my FDM printer.

.1mm layers is fine for this and recommend ABS or ASA for the material.

Zip has the cad file if someone wants to edit the original and a clean stl file in mm for the slicing software.

Thanks,

Ken

Headphone drop could be interference. On the MK or Gold Racer, and Apex I would change channels and it would solve it.

Can you change channels on BT?? That could be a problem if not.

Does seem pricey especially when the Simplex and other machines are out. The magnetic contacts for charging is something XP should have done ages ago. 7.5khz is a descent frequency for a sf machine though.

Would think it would be much less $$$ since the control box is the phone.

Spec's don't look bad, curious on performance and control features.

Very cool. Need to get some measurements over to Steve, see if I can replace the Kruzer's shaft to one of those.

Isn't the base shaft (without coil and control box) only 8.6oz? Incredible!

Nice run for half hour so you found 4 things, dime, penny, junk ring and some fresh air!

There are home health aids that can help you and your grandma, much better than a home.

Surface is a little rough, have to fiddle with the settings on the printer but dimensionally accurate. Coil cover is semi solid so should be better around undergrowth etc, less hangups.

Printed in PVA, ABS or ASA would be better. If anyone likes I can post a link to the cad file.

Marks on top of my coil is from old glow in the dark duct tape, used to do a bit of hunting at dusk and low like, helped me see where the coil was for digging. Will put new tape on when I get around to it. 🙂

With my Seahunter if I have it off the ground at the beach depth isn't too good but if I skim the wet sand it hits very deep with strong signals. Saw somewheres on noobtube saying it is coil loading. I don't know more than that and results I have.

Might have to test with my pulsedive.

Coil loading?

Ok, my honest opinion:   That machine is jumpy and quivering.   I'm sure you could lower the sens, and get it to "quiet down".   But the amount of quivering and fluttering I saw would not be pleasant , in my book.

 

Who's that handsome guy with the rippling biceps and 6-pack abs that comes in the scenes starting at 9:33 ?  😏

I noticed that too. On the Multi Kruzer if I use beach mode and GB isn't spot on it will get noisy. I usually manually ground balance and can get the machine running super quiet.

Might be worth trying a manual GB on the Legend and see if that does the trick.

I don't keep them fully charged, run the externals then internals. Less cycles on both in the end.
