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...

Is it ok to remove noisy data?

Posted by Sean on Nov 08, 2019


Here in North America, we're moving into the colder months of the year. And while some of us will brave the elements this season and do some cold-weather surveys, many of us will be indoors looking through the data we collected over the Summer.  So it’s a good time to start talking about the kind of work that's done off of the field—like data inversion. In this post, we want to discuss data filtering in particular.


Over the course of our...

A look back on 30 years...

Posted by Sean on Oct 24, 2019


As you may know, we’re currently celebrating 30 years in business. And as we were looking back through the past three decades, we were struck with all of the things that have come (and gone) since we started doing business in 1989. 


From technological advancements like HTML and Wi-Fi, to cultural touchstones like Emojis and Y2K—so much has happened in 30 years. So we thought we would have some fun and put together the graphic below showing some interesting things that have...
