new handheld magnetometer

[Unregistered]

Hi,

I wanted to let everyone know that I have developed a handheld magnetometer. It uses 3-axis magnetoresistors and with filtering it can measure 1e-5 gauss. The unit is sold here:

I'm happy to answer any questions as well as provide support and improvements to the open source firmware.

"with filtering it can measure 1e-5 gauss"

I'm new to magnetometer and was wondering what that meant?

Also how long will a fully charge battery last?

Thanks
