Bartington offer one which is widely used in the UK for Archaeological purposes. And is very effective at that.

Also, I am not asking about triaxial systems. I do not mean measuring the 3C of the total magnetic field, I mean measuring the gradient (or spatial derivative) at a specific site of the total magnetic field. Instead of calculating the vertical gradient or the horizontal gradient with whatever software in the market, I would like to measure it. GEM Systems / TerraPlus offer vertical arrays with the GSM-19. VTEM offers horizontal arrays.

Hasn’t any one watched the British TV show “Time team” using triaxial mags for archaeology? I think they were fluxgates made by Bartington. Anyway plenty of others . Geometrics?

However, I see that Sergio is asking for a ground triaxial gradiometer.
