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...
The Gold Mining Industry is Geared to Ramp Up
Posted by Sean on Sep 23, 2019
At the time of writing this blog post, over 70% of economists are forecasting an economic recession within the next 1-3 years. This forecast is due to all sorts of geopolitical happenings right now. At this point, we’ve probably all have seen the articles on Forbes, the Washington...
Dodging Disaster: How To Monitor Dams & Levees With Geophysical Methods
Posted by Sean on Sep 10, 2019
A quick note before we begin, this blog post is specific to earthen/embankment dams and levees. The electrical geophysical methods we mention below aren't used to monitor dams made of concrete, rubber, timber, or non-conductive materials. If you’re questioning if a geophysical survey is needed for your dam, contact us for a quick chat. Our team of geophysicists will be happy to help!
Before we discuss geophysical safety measures, let’s look at some reasons why dams and levees fail.

What Array Is The Best?
Posted by Sean on Aug 14, 2019
We’ve gone over several electrode arrays and resistivity methods in a recent 11-part blog series. We’ve covered common arrays like Wenner, Schlumberger, Dipole-Dipole, Pole-Dipole, and Pole-Pole. We’ve also covered some uncommon array types like...
Bipole-Bipole Array: Electrical Resistivity Methods, Part 11
Posted by Sean on Jul 29, 2019
It’s been a long journey, but today we’re at the end of our 11-part series discussing Electrical Resistivity Methods. In this final discussion, we’re going to give you an overview of the Bipole-Bipole Array.
Don’t worry though, we plan to do more long-form series like this in the future about different topics!
And if this is your first time joining us, you’re in for a treat because we’ve also covered all of the following methods:
EarthImager Demonstrations with Hasan Aktarakci and Eduardo Rodrigues
Posted by Sean on Jul 23, 2019
Throughout July, our Madrid office has been hosting webinars to demonstrate the basics of EarthImager™ 1D, 2D, and 3D. Some of our customers—especially those who signed up for webinar alerts—were lucky enough to attend the free webinars. There, they could ask questions and watch the hosts use the software in real time. We shared a lot of useful information during these webinars so we don't want to keep them hidden away! Below, you can find all of the webinars—including the ones hosted in Spanish.
And if you ever...
