Underwater expansion for Bluestone

Plymouth-based underwater electronics company Bluestone Technologies is expanding its business to support increased demand


Plymouth-based engineering company Bluestone Technologies, which pioneered the underwater computer monitor, is expanding its business to support increased demand.



Bluestone used financial backing from HSBC to support the expansion, taking on full-time staff and opening a new industrial unit in the South Hams.


Founders Robert Short and Andy Mawe, who have a background in product design and manufacturing, created a unique range of waterproof, dive-proof and sunlight readable LCD monitors. The company has now developed into a market leader for specialist computer monitors and has recently won contracts from Bristol University, the RNLI and the Ministry of Defence.


Its latest product is a specialist, remote monitor that can connect wirelessly to a PC up to 30m away, which is designed for environments hostile to computers. The company has also developed a PC monitor that can be used up to six metres underwater.


Bluestone’s products are being used in Harrier Jump Jets and the Trident nuclear submarines, and most recently we the company has completed a £65,000 contract from Bristol University to fit monitors in their new anatomy teaching suite.
