The needle in a haystack finder
SeaQuest is the ultimate magnetic target detection platform. It gives you more information, and helps you see just what you want to see
The Overhauser Effect
Marine Magnetics’ SeaQuest gradiometer measures the ambient magnetic field using a specialized branch of nuclear Magnetic Resonance technology, applied specifically to hydrogen nuclei.
SeaQuest sensors deliver high-resolution output with a noise level of 0.01nT; counter sensitivity is 0.001nT.
Highest Absolute Accuracy
SeaQuest has the best absolute accuracy of any marine gradiometer: 0.1nT.
Worldwide Operation With No Restrictions
SeaQuest is entirely omnidirectional, meaning you never have to orient your sensor because it is already optimized to work around the world. As a result, regardless of where you are in the world and no matter what the magnetic field strength is, your SeaQuest sensors will continue to provide a strong signal and accurate data.
Maintenance-Free Sensors, No Realignment and No Consumable Parts
SeaQuest Overhauser sensors are entirely maintenance free and most importantly, SeaQuest’s specifications do not degrade over time. As a result, SeaQuest sensors, unlike optically pumped sensors, never have to be realigned or recalibrated in order to meet the manufacturer’s specifications at the time of shipping.
Stability and Durability
Accidents happen. SeaQuest’s hard-anodized aluminum frame is ready for them, providing strength and rigidity while keeping weight down. Most of the frame is covered with an ultra-tough and flexible composite that forms the surface area of the wings protects the frame from impact.
All cables are contained within the pressurized sub-housings, or within the hollow free-flooded wings. This, coupled with its sleek, swept design minimizes the ability to snag foreign objects and debris. The entire structure is designed to deflect impact rather than absorb it.
The bottom-wing ballast weight keeps SeaQuest’s center of gravity lower than the towing axis, keeping pitching and rolling motion to a minimum. The large surface area of the wings ensures that the platform will tow straight and smooth, even in high sea states. All this comes together to produce the highest quality data possible in a towed marine gradiometer.
