divers

Nowadays most work at 400m+ is done by ROVs instead of human divers due to cost and safety.

And the USA retail price that divers pay for helium has roughly tripled in the past 15 years.

The dangers in sending down divers to pick strawberries alone make it not practical as a business.

This is something that scuba divers are aware of, because of the way water plays with sound.

It's certainly not being built by dumpster divers managing to convince other people that dumpster diving is somehow noble.

The sign used by divers to alert others is banging your knife against the air tank.

The fact that there are dumpster divers points to there being wasteful behaviour in our society.

A number of divers mitigate that by having a separate independent fourth O2 cell, monitored by a separate computer (from another manufacturer).

Having said that, I think these advantages are mostly important for niche uses - scuba divers for example.

Many of us scuba divers now carry Nautilus radios which include a GPS receiver and 2-way VHF marine radio with distress beacon.

Built with the user in focus, Oceans makes it easier than ever to check-in diving adventures and interact with divers around the globe.

We are building a community for divers and explorers worldwide, allowing them to share and discover dive sites and observations across the world’s oceans.

Divers are trained to watch for any sign that the computer isn't doing its job (and there are certain typical indicators, although they don't cover every possible scenario), and if there's any doubt, switch to an alternative (either bailout to open-circuit, or switch to a fully-manual mode of operation) - either way, the computer is then out of the picture.
