SwissKNife

Versatile

SeaQuest is 100% compatible with our high-sensitivity SeaSPY magnetometer, both mechanically and electronically. The SeaQuest platform also supports the SeaSPY side scan sonar interface, allowing simultaneous towing with industry standard digital side scan sonar systems.

3DSonar

Multidimensional

SeaQuest is the only marine platform that can measure the complete 3 dimensional gradient vector, quickly, accurately and in real time. The 3D magnetic gradient suppresses geological noise, while showing small, near-surface targets with higher resolution than the total-field data produced by conventional magnetometers.


Crab

Tough Exterior

SeaQuest has a heat treated, hard-anodized aluminum frame that offers superb strength and rigidity, while keeping weight down. An ultra-tough and flexible composite forms the surface area of the wings.


TGV

Real-World Ready

SeaQuest is designed to deflect impact rather than absorbing it. All cables are contained within the pressurized subhousings, or within the hollow free-flooded wings. This, coupled with its sleek, swept design minimizes the chance of snagging foreign objects and debris.


OceanMine

Ideal for Marine UXO

SeaQuest shines when searching for unexploded ordnance, which has a tendency to be buried and requires a high detection reliability for safety reasons. From bombs to warheads to projectiles, SeaQuest’s total gradient data will maximize detection capability, and minimize interference from geology and environmental sources.

Easy Rider

A bottom-wing ballast weight keeps SeaQuest’s center of gravity lower than the towing axis, so pitching and rolling is kept to a minimum. The large surface area of the wings ensures that the platform will tow straight and smooth – even in rough waters.

More information

Horizontal gradiometers measure the gradient in one axis (direction) only. This is their limiting factor. If your heading changes by even a few degrees when surveying with a single axis gradiometer, you are no longer measuring the same gradient.

SeaQuest measures the gradient in all three axes simultaneously, producing a total gradient result that is independent of orientation. No matter how your heading changes no information is lost.


BullsEye

Dead-on

Like all our mags, SeaQuest gives you the highest absolute accuracy available, 0.1nT – with no drift, temperature dependence or heading errors to worry about.


Scope

Performance

SeaQuest’s sensors are synchronized to within less than 0.1ms by a single electronics unit, which eliminates noise caused by steep or quickly changing gradients.

The integrated tilt sensor continuously monitors the tiniest platform movements caused by rough seas, telling you exactly how ‘horizontal’ and ‘vertical’ the gradient measurements are.

The echosounder/altimeter can be useful in finding very small targets by helping you keep the SeaQuest close to the bottom. Some of our customers even use it for bottom-tracking, where an operator operates a winch and pulls on the cable to bring the tow body up while letting out cable to send it down.

The altimeter measures bathymetry with 0.1m precision, and high reliability over soft or hard sea floors. It’s the ideal tool for quality-controlling minimum depth requirements, or for bottom-tracking a heavily contoured area.
