Ok, only this time I will give only one info!
The magnetometer accessory (horizontal part) has 4x FLC-100 type sensors in it.
It works very precisely and realistically.
And that's what drew me to the whole story.
Since 2018, I have my magnetometer project. I have been dealing with this topic since 2004/5.
I really like the 4 sensor setup. It makes a lot of sense. And "some interesting things happen there"!
Perhaps I will devote this coming winter to developing my 4-sensor magnetometer.
It's hard to plan in these crazy times. We do not know what the day brings and what the night brings.
But here... enough "material" for further thoughts.

I guess this is not for magnetometers.
These types of devices are on the market. Magnetometers are good for ferro metals. Are they sensitive to non-ferro metals as well?

The original device mentions a 3km range. = they wish, they even can not demonstrate 5m range.
I think I contacted them a few years ago, they praised the product very much, but when I asked for a video showing how far they can detect a nail, they went silent.
The detection range depends on the sizes/weights of the targets. As claimed by Geometrics for G-882 Marine Magnetometer:
Ship 1000 tons: 0.5 to 1 nT at 800 ft (244 m)
Anchor 20 tons: 0.8 to 1.25 nT at 400 ft (120 m)
Automobile: 1 to 2 nT at 100 ft (30 m)
Light Aircraft: 0.5 to 2 nT at 40 ft (12 m)
Pipeline (12 inch): 1 to 2 nT at 200 ft (60 m)
Pipeline (6 inch): 1 to 2 nT at 100 ft (30 m )
100 kg of iron: 1 to 2 nT at 50 ft (15 m)
100 lbs of iron: 0.5 to 1 nT at 30 ft (9 m)
10 lbs of iron: 0.5 to 1 nT at 20 ft (6 m)
1 lb of iron: 0.5 to 1 nT at 10 ft (3 m)
Screwdriver 5 inch: 0.5 to 2 nT at 12 ft (4 m)
1000 lb bomb: 1 to 5 nT at 100 ft (30 m)
500 lb bomb: 0.5 to 5 nT at 50 ft (16 m )
Grenade: 0.5 to 2 nT at 10 ft (3 m )
20 mm shell: 0.5 to 2 nT at 5 ft (1.8 m)
