Any feedback about quantrosensing Discovery underwater handheld magnetometer????

[Pascal Prado]

Hi everybody,

I'm interested in handheld underwater magnetometers.

I found a promising product called Discovery, from quantrosensing (http://www.quantrosensing.com/handheld.htm).

However, I'd like to get some feedback from previous users about:
- the product,
- the company (are they still around?) and
- the ease of use of this kind of survey equipment.

Anybody can help me?

Thanks,

PP.
