We started this business in the mid 90’s because it was apparent that the industry had stagnated. Innovation was at a standstill, established organizations were complacent, and customers lulled into accepting the status quo. We saw an opportunity to carve out a niche for ourselves by raising the bar.

That worked, so we decided to keep doing it.

Focus

As engineers dedicated to the singular goal of creating smarter sensors, we don’t make geoelectrical equipment, seismographs, or even land or airborne magnetometers – our best minds are zeroed-in on the task at hand.

Why? Because designing mags that boast the highest independently tested sensitivity in the world takes focus.

Our Secret

Our success is rooted in the combination of Technology and Design that takes the user experience into account. We know exactly what you intend to do with our products. We’ve researched the conditions and situations in which they must perform. And we’re realists: Accidents happen. People make mistakes. Our systems are built to survive them.

Technology

The Overhauser Effect

Our Overhauser magnetometers measure nuclear magnetic resonance spectral lines that exhibit excellent accuracy and long-term stability characteristics. Our mags are easy to use, and get you better quality data.

Design

User Centric

Accidents happen. People make mistakes. Weather is unpredictable. Our systems are built to survive in all kinds of conditions.

Instant Awareness

Power LED’s let you see, at a glance, the status of the tow system, if a connector is unplugged, or even if there is a short in the tow cable. A separate blue LED flashes when communication is detected over the link, showing that the towfish is ‘alive’ and collecting data.

Power Protection

The topside unit regulates power to the towfish, ensuring that the power reaching the towfish is always safe and reliable. In case of an overload, the transceiver automatically shuts the system down, avoiding damage. Towfish power is also isolated by the topside unit, preventing any possibility of ground loops or towfish corrosion, regardless of the quality of electrical power on board the vessel. And the towfish itself is protected against reverse voltage, in case the tow cable is wired incorrectly.

Leak Protection

The towfish contains a sensor that is triggered by the smallest drop of water. In the event of a leak, the towfish instantly sounds an alert, so the faulty seal can be repaired with no damage to the instrument. Because the electronics and sensor are individually sealed, they are not damaged by the presence of water in the main housing.

Maintenance-free

Our sensors don’t degrade over time, require no recalibration, and contain no consumable parts. Our towfish are constructed with strong, durable materials that withstand even the toughest conditions. Any protruding elements, such as fins, are designed to break away in the event of a snag or strong bump, with no damage to the rest of the unit – and are easily field-replaceable as spare parts.
