Ocean reef IDM

Very true words from the president of ocean reef yesterday about using underwater communication units: yes you don’t want to hear talking all the time bu. when you go into the mountains you take communication with. When people fly they take communication with, when they go into remote areas they take communication with, but when they go dive they don’t take anything with. How do they tell the boat or other divers there is a problem, and for that reason ocean reef came up with the IDM and communication systems. Not so your wife can talk to you all the time
