What others are saying about NavDive...
NavDive was featured in Maritime Heritage Minnesota's Lake Minnetonka Nautical Archaeology 2 Project Report (downloadable here). In this report, Dr. Ann Merriman and Chris Olson, founders of MHM, reported the following regarding a wreck found using NavDive and later confirmed via side scan sonar:
"MHM did not recognize the acoustical signature of the St. Louis Bay Wreck during the sonar survey or during sonar review because of the fragmentary and buried nature of the wreck. In simple terms, she does not look like a submerged cultural resource in the sonar footage. Kelly used an underwater navigation system he designed and developed through his company Applied Logic Engineering, Inc., to record the wreck's precise coordinates. The diver controls NavDive underwater, connected to a GPS unit at the lake surface that is attached to 'diver down' inner tube. The unit travels with the diver and the GPS coordinates are relayed in real time to the diver through a cable. The coordinates provided by Kelly through NavDive allowed MHM to pin-point the wreck in the sonar footage. In short, if Kelly had not found Anomaly 41.2 she would have evaded detection by MHM."
