Should You Use 1D, 2D, or 3D ERI For Groundwater Exploration?

Posted by Sean on May 16, 2022

We’ve discussed groundwater several times on our blog and educational series. We’ve discussed how to find it and shared a few successful cases of finding it with ERI techniques. We’ve also compared 1D, 2D, and 3D survey types in a...

Quick Tip: Using an AGI Soil Box for Soil Tests

Posted by Sean on Aug 27, 2021

We’ve covered the ASTM G57 soil test and IEEE standard grounding test on the blog before. In many cases, these standards will be your go-to solution for your soil test/grounding project. However, in some cases—the ASTM or IEEE tests show too high values so grounding wells need to be installed for power systems. Dry and arid soils typically found in desert environments can often produce these kinds of results.


In order to get a more accurate reading of...

The difference between True 3D and Linear-Measured 3D Resistivity

Posted by Sean on Jun 22, 2021


In a previous post, we briefly spoke about the difference between 1D, 2D, and 3D Electrical Resistivity Imaging (ERI) surveys. In our recent blog post about the amount of channels you need for your Resistivity system, we touched upon the two types of 3D ERI surveys one can do—that is, true cross line measured 3D and linear-measured 3D. Let’s dive deeper into this topic and see what the difference is between the two types—and which is better suited for your...

How does a marine electrical resistivity survey impact fish?

Posted by Sean on May 12, 2021


Perhaps you’ve seen our April Fool’s Day video for this year, where we joke about our cables being used for high-octane fishing. While our cables cannot take down a 400lb (181kg) swordfish, you may be asking yourself—how do the electrical currents used in marine resistivity surveys impact smaller fish?

As we’ve seen in a previous post, animals tend to have an attraction...

Why having more than 8 channels does not mean better surveys

Posted by Sean on Apr 06, 2021


In a previous post, we emphasized that Electrical Resistivity Imaging (ERI) surveys don’t need a lot of power. In today’s post, we’re going one step further. We also believe that resistivity metering instruments don’t need more than 8 channels to complete fast, quality surveys. 


Now, you may be saying “But AGI, you said that 8 channels are faster than 1 channel in this blog post. Shouldn't 12 channels be faster...

The Benefits of a Weak Dollar (UPDATED)

Posted by Sean on Oct 13, 2020

The original article was posted 2/27/2018. 

[Update 2/13/2020]

With the Euro trending upwards again, we thought it was time to remind everyone that a weak dollar can get European customers new—American-made—geophysical equipment at a fraction of the cost.


Let’s face it, no one wants to hear that their currency is weak—especially Americans who may not want to hear that, as of right now, the US dollar is weak and the Euro is on top....

Power vs. Signal: Why more power doesn’t mean better resolution

Posted by Sean on Jun 05, 2020


We know it sounds crazy, but more power output doesn’t mean you’ll have better surveys. 


It’s understandable that most of our customers don’t initially believe us when we tell them this. In most industries—especially electronics—more power equals better, right? But ultimately they understand when they see the proof. Today, let us explain why we say that power isn’t the most important spec that you should be looking for when shopping for an Electrical Resistivity meter. Ok, let's get into it.


So what spec is...

Using Electrical Resistivity to Detect Leaks in Pond Membranes

Posted by Sean on Apr 08, 2020


In this blog post, we’re discussing ponds with leaking geomembrane liners. And more specifically, flexible and impermeable plastic liners. If the techniques in this article interests you, you may want to check out a similar article about detecting leaks in earthen dams and levees.


Ponds can serve as an attractive asset that adds value to your property. In industrial applications ponds can hold strong solvents. Whether it’s for practical or aesthetic purposes, the whole point...
