I I have just seen an interesting website suggesting they have come up with a GPS for divers called Navimate
I If this is true then we are about to see major revolution in Diving. Can someone who knows how GPS works shed
some light on the subject. This is the site take a look and see what you think
Hello Lorima,
This is not a true underwtare GPS as the Signals from the GPS satellites won't penetrate water.
The idea is that the signal from a GPS locates the boat and then the boats has a tranceiver that sends (I presume) a sonar signal to where the diver is and thats what is received.
Thats leads to a lot of errors along the way. GPS signal is good for several meters error, sonar tranceivers have also several meters errors (due to things like water temp etc).
Would not use this as a totally accurate method of finding people or getting around. Good navigation skills and a compass work well and are far more reliable.
