GPS satellite signals are no match for the ocean or large lakes, keeping scuba divers stuck in the dark ages, with only compasses to guide them. In low visibility conditions, this can be a real problem, says Gene Bivol, a cofounder of the underwater GPS company DiveNET.</p><p class="EkqkG IGXmU nlgHS yuUao lqtkC TjIXL aGjvy ">“It’s easy to get disoriented when you’re weightless and moving in three dimensions,” he says. “Plus, you have a lot of other things going on: You’re controlling your breathing, you’re managing your buoyancy, and you have no navigation information at all besides a compass.”</p><p class="EkqkG IGXmU nlgHS yuUao lqtkC TjIXL aGjvy ">Bivol’s company has come up with a small-scale solution to that problem.

The divers wear receivers that show them, in real time, where the other members of their group are, where the dive boat is, and points of interest on the ocean floor. “In the future, you might even have an underwater drone videotape your dive for you,” Bivol says.</p><p class="EkqkG IGXmU nlgHS yuUao lqtkC TjIXL aGjvy ">(<a class="zZygg UbGlr iFzkS qdXbA WCDhQ DbOXS tqUtK GpWVU iJYzE " data-testid="prism-linkbase" href="https://www.nationalgeographic.com/travel/article/diving-into-the-first-underwater-museum-in-greece" rel="noopener noreferrer" target="_blank"><i class=" ">Dive into Greece’s first underwater museum</i></a>.)</p><p class="EkqkG IGXmU nlgHS yuUao lqtkC TjIXL aGjvy ">The U.S. military has been working on a similar system of sonar-emitting buoys that can function like GPS satellites, but experts say that this kind of grid is impractical. </p><div class="oLzSq QrHMO fnRUo pvsTF EhJPu vPlOC zNYgW OsTsW RMeqy daRVX ISNQ sKyCY eRftA acPPc MENS nFwaT MCnQE mEeeY SmBjI xegrY rPLsU iulOd NIuqO zzscu lzDCc aHUBM IEgzD OjMNy eQqcx SVqKB GQmdz jaoD VWDdR ONJdw vrZxD OnRTz gbbfF roDbV GPGwb oMlSS gfNzt oJhud eXZcf zhVlX "><div class="natgeo-ad" data-testid="prism-ad-wrapper" style="min-width:300px;min-height:250px;transition:min-height 0.3s linear 0s" data-ad-placeholder="true"><div data-box-type="fitt-adbox-fitt-article-inline-box" data-testid="prism-ad"><div class="Ad fitt-article-inline-box ad-slot " data-slot-type="fitt-article-inline-box" data-slot-kvps="pos=fitt-article-inline-box"></div></div></div></div><p class="EkqkG IGXmU nlgHS yuUao lqtkC TjIXL aGjvy ">“I don’t see them being able to crank up the acoustic levels to a point where they can cover hundreds of square miles of ocean.

But, technology can fail, and a zoomed-in digital map on a phone lacks the local detail and broader regional context of a larger paper map.
