Mesotech Systems Ltd. founded in North Vancouver, BC by four local entrepreneurs. The original office was located at 1174 Welch Street, North Vancouver. The name "Mesotech" was derived from the Auguste Piccard "mesoscaphe".


From 1973 to 1974, Mesotech Systems develops the first Underwater Telephone, first Pinger (27kHz), first Pinger Receiver, first Acoustic Release Transponder, and first Transponder Interrogator.


Geophysical Logging Trucks for uranium exploration: Downhole probe with resistivity and gamma sensors, and a van with a winch and boom and instrumentation for recording and control. Custom design for Wyoming Minerals.


Recall Buoy: An acoustic release system built for Dome Petroleum and deployed in the Beaufort Sea. These recall buoys were attached to the drillship anchors before they had to leave before freeze-up. The anchors were left in place and in the spring, the buoys could be recalled and would pop up with a rope attached to the anchors. This way the drill ships could be anchored in the exact position they left, and the drill shaft would line up perfectly with the drillhole.


EEL: Geophysical Logging Instrumentation similar to the logging trucks, but deployed in a 20’ flexible tube (which we named “EEL”). It was pulled by a boat along the bottom of a lake in Saskatchewan.

The 952 Profiling Sonar released: Sonar for bottom profiling with plotter records 0.225 deg resolution using stepper motor.


Mesotech Systems moves to 2830 Huntington Place, Port Coquitlam.

The 515 Microprocessor-based Transponder released: Modular system with motherboard and plug-in boards (like the 1071 stack but the boards were about 6” in diameter).


The 961 Profiling Sonar released: Fast sector profiling using a DC motor and encoder for angular position; profiles displayed on a monitor.

The 440 Navigation System was developed, consisting of: 440 Processor, 520 Telemetry Module (for tethered submersible of tow fish), 516 Range Module (long baseline), 518 Bearing Module (short baseline), 517 Orientation Module (compass), 515 Transponders, 519 Responder, 265 Remote Responder, and 315 Power Supply. This was a huge and challenging project for Mesotech. We had an order from IOS that covered some of the development cost and they also provided their research vessel for sea trials.


The 965 released: High Precision (0.1deg beam) Dual Axis Profiler, nicknamed Underwater Theodolite. Designed to place seabed mats and install locks in the Netherlands.


The 514 Ice Keel Profiler released: An up-looking sounder deployed on the seafloor over the winter to measure the depth of icebergs floating by.
