Bristol Undersea Systems  Ltd was founded to supply top quality lighting and video equipment direct to divers at affordable prices, Based in a city famous for its engineering excellence and maritime traditions we can draw upon skills normally used for aerospace and defence engineering.

Our products are designed by divers for divers, to be practical and durable as well as using the latest battery and LED developments.

As divers we are keen to protect the environment, and so we take care to avoid using harmful substances in our products. We only make rechargable torches, as disposable batteries can seriously damage sensitive sites.

We now offer a design consultancy service, making our wide experience available to assist other companies. Our team has worked with television transmitters, particle accelerators, air traffic control radio, magnetic resonance body scanners and a variety of of radar and communication systems. We can do a whole product service, including enclosure, power supply and built in test equipment, but our speciality is high power RF amplifiers, using GaN, GaAs, LDMOS and VDMOS devices.
