The Mag Pro II is so rugged and reliable we back it with a LIFETIME warranty!

The Mag Pro II is the first and only, truly user-friendly, portable, precision single-axis gradiometer on the market!  The LCD panel meter on the top of the unit displays the magnitude of the magnetic field gradient in milligauss. In addition, the unit uses a variable frequency audio output signal that is directly proportional to the magnitude of the external magnetic field gradient.  

Augment the standard audio and visual outputs with a  data logger using the Mag Pro II's output jack and hook up to T and D Model VR-71 data logger or a Lascar EL-USB-3 data logger. The data logger option allows even greater flexibility as to range, sensitivity, and data graphing capability using the Microsoft Excel compatible software. The data loggers are sold separately.

Key Features of the Mag Pro II
• Calibrated Magnetic Gradiometer, Accuracy – 1%
• Three Full Scale Ranges – 2,000, 200, and 20 milligauss
• Ruggedized for extended field use in harsh environments
• Operating Time – 40 hours from 4 “AA” Alkaline batteries
• Data Logger output jack (data loggers sold separately)

• Manual and carrying case included
• Lifetime Warranty
 

We won’t be surprised if the Mag Pro II soon becomes the instrument of choice for Geologists, meteorite hunters, archeologists, hydrologists, and geophysicists. Not only is it a great instrument for professional scientists; but as a geophysical survey tool you can expect to see it in the hands FBI technicians, pipeline survey crews, Crime Scene Investigators, EPA personnel and military EOD personnel, just to name a few.  With the Mag Pro II you can survey a field, meadow or shallow water in minutes and locate any buried ferrous anomaly (Knife, gun, pipe ends...). The Mag Pro II is great for pinpointing magnetic "Hot Spots" and then displaying the magnitude and direction of the individual magnetic field components.

Optional data logger

Lightweight and user-friendly, the state-of-the-art, Mag Pro II Magnetic Gradiometer packs all of its sophisticated electronics in an incredibly light 2-lb package. Shock-mounted sensors maintain proper sensor alignment, even when exposed to normal physical abuse.

Without a doubt, we think you'll agree the Mag Pro II is the definitive instrument for performing precise magnetic surveys of any area.  In particular, you can precisely pinpoint and identify buried iron or steel pipe, survey markers, water valves, water meters, 55 gallon drums, or any other ferrous object covered by dirt, pavement, water, snow or ice.  It's capabilities are limitless.  An experienced operator can find many uses for the Mag Pro II.

The Mag Pro II typically provides over 40 hours of operation from standard, AA alkaline batteries.  The Low-Battery indicator eliminates those unwanted surprises by providing ample warning of fading batteries 2 to 3 hours before they fail, a real convenience in the field. 

Complementing the easy-to-read digital display, the Mag Pro II also uses an audio output which increases in pitch as you approach a magnetic target.
