Landviser’s on-line store is being re-created

Landviser, LLC is a small geo-consulting family owned company with offices in Houston, TX and Moscow, Russia. We develop and sell Electrical Geophysical Devices & Geophysical Imaging Software and also provide Consulting & Training Services in Geophysics, GIS, and Basic Soil Science. Our exclusive hand-held LandMapper devices are geared toward near-surface geophysical explorations (<25 m depth), and most suitable for archaeological, forensic, engineering, agricultural, ecological and hydrological applications. Current model, ERM-02 - electrical conductivity (EC), resistivity (ER), self-potential (SP) - is highly portable, accurate and very competitively priced (<2,500$US). Basic model, ERM-01 - electrical resistivity only - (<1,600$US) is also available. We have expertise in other electrical geophysical equipment, used for deeper geophysical prospecting, such as AGI and ABEM systems.
Our on-line store is being re-created. Meanwhile, you can still place orders for LandMappers ERM-01/ ERM-02 and accessories, GIS consulting, or geophysical software RES2DINV / RES3DINV. Download our Catalog or contact us for personal quote. We ship worldwide and accept PayPal, VISA/MC and wire-transfers to our US bank account.

Landviser develops innovative non-invasive technologies (hand-held equipment and software) for mapping and monitoring core biosphere components: soils, plants and groundwater. We provide custom research system integration and consulting on electrical geophysics applications in agricultural and environmental sciences; GIS; geostatistics; and remote sensing. Depending on your project we can assist with equipment/software procurement and develop training courses in geophysical equipment (ERM-02 and ABEM) and software (GIS, seismic and resistivity imaging). We are an international consulting company with headquarters in Texas, USA and business contacts in Canada, Russia, Malaysia, Philippines, Middle East, China and South America. Please, do not hesitate to contact me, Larisa Golovko (Pozdnyakova) - info@landviser.com

LandMapper ERM-01 is a hand-held resistivity meter which accepts Wenner (as well as any other four-electrode arrays, dipole-dipole or square ones f.e.). It can sense down to 15 meters in most soils. You can use hyperlinks to download our publications about LandMapper and popular geophysical freeware/shareware. 
LandMapper ERM-02 measures electrical resistivity (ER), electrical conductivity (EC) and natural electrical potential (EP) from soil surface down to 25 m depth as well as in soil pits, pots, samples, pastes and water solutions. Don't let the small size fool you - LandMapper ERM-02 measures electrical parameters in a widest range possible (from ultra-pure water and rocks to ocean waters) with the accuracy comparable to the standard devices used in electrical geophysical prospecting, like ABEM, Syscal, etc,  but weights and costs TEN times less!
The applications of LandMapper are not limited to soils but can be extended to any semisolid media and even live plants! Download new LandMapper ERM-02 brochure or complete manual.
We now have limited quantities of both models in stock - basic ERM-01 with resistivity mode only for $1,579 (sug. retail) and ERM-02 (resistivity, conductivity, and self-potential) for  $2,437 (sug. retail).  Probes and arrays can be easily constructed from common hardware, but we can build probes to your specs for very reasonable price and can provide other accessories.
Note, that we also offer dealers' and academia discounts on equipment and software!

Setting up RES2DINV/RES3DINV (DEMO ver.) for the first time

Download DEMO version of RES2DINV from http://www.landviser.net/webfm
Visit hyperlinked pages to download DEMO versions of RES2DINV and RES3DINV and supplemental publications.
Note, that you can use RES2DINV without RES3DINV, but not other way around - RES2DINV have to be installed first. This demo software has decreased functionality, but it might be enough for your research and the DEMO versions never expire.
However, if you decide to purchase software, please request a formal quote from us ASAP before contacting GEOTOMO directly, as we will meet or beat price of other dealers, but we cannot guarantee it unless you secure order from us first.
Now, installing the software…
Click setup.exe and follow directions. When you run through set up series of questions, click OK to the question about dongle installation.
Setup will quit.

Then run the program from Start\Programs\RES2DINV or from folder where it has been installed.

Without a dongle you will see SemiDemo version. Click OK.

Big white screen will be there with menus on the top. If you see white screen only, my guess it is screen resolution on your PC system that makes it blown out of proportion. I did installed mine on VISTA Ultimate 64-bit using same file without any problem before, but today I happen to have Win XP 32-bit computer without RES2DINV, so I run setup.exe on it step by step. Works fine.

Go File/Run Jacobwin if you using a program for the first time. It will calculate partial derivatives for most popular arrays. You will not need to run it again ever on the same computer.


When you decided to purchase and receive your USB dongle in the mail, follow directions to install the dongle published in manual book. You will not need to un-install DEMO versions, the software will pick up dongle if it attached otherwise it will continue to run in semi-demo mode.

If you run into any problems with installation, please, do not hesitate to contact Landviser or post a comment in this blog.
