Explorer

Featherweight

4.5kgs, soaking wet: Explorer is the world’s smallest and lightest high sensitivity magnetometer without export restrictions. It’s ideal for inshore shallow water work, or offshore towed behind Side Scans, AUVs and ROVs.

Applications:

Ideal for precise offshore survey control

Deployments:

AUV/ASVSide Scan

Made to Integrate

We’ve reengineered our total-field magnetometer for neutral buoyancy so it can follow the path your AUV takes without sinking or floating upwards. It’s ideal for inshore, shallow water work, or offshore towed behind Side Scans, AUVs and ROVs.

It’s ideal for inshore, shallow water work, or offshore towed behind Side Scans, AUVs and ROVs.

From 4.5 kg on the deck to neutrally buoyant in the water.

Precisely follow the path your AUV takes without sinking or floating upwards.

Use RS-232 to connect to most AUV/ASV systems.

Build Quality

Specialization matters

Ultra Low 2 W Power Consumption

Explorer can be powered by a single car battery for up to 200 hours.

One Person Operation

4.5 kgs (9.9 lbs) for the mag 6.9 kgs (15 lbs) for a 50m (164 ft) tow cable

High Sensitivity Without Export Restrictions

With 0.02 nT sensor sensitivity and 0.001 nT counter sensitivity Explorer maintains high sensitivity, without requiring an export permit

Maintenance Free Sensors

No realignment and no consumable parts.

Make Explorer AUV a perfect fit for your application.
