If you’re interested in Archaeological Diving in the Caribbean it would be worth you looking at the ADMAT website http://www.admat.org.uk/ for further information. We have been working with Simon Spooner for several years. They’ve made some great finds and are always looking for divers to help with the work. If you’re a BSAC diver, they’re Branch number 2349 !
It would also give you a chance to try out the AQ1B metal detector and DX200 hand held magnetometer.
