I am 16 years old and just got into freediving. My maximum depth 60 to 70 feet and i am hopeing to get better this summer. Now u are probably thinking where does he freedive in ontario? well i freedive in georgian bay the maximum depth in this bay is 600ft. The water is crystal clear on a good day u can see 75 feet, there is lots to look at from underwater caves, ship wrecks and some big fish!!
