Just an update on the BCRF website showing our new cave sonar (pingers) being used to create an interpretive trail above the amazing underwater passages in Dan's and Ralph's Cave on Abaco Island, Bahamas.
This work is possible entirely due to the use of equipment designed and donated by Australian Ken Smith. Thank you Ken!!
