I have fished southeast Florida waters for over 50 years. I rarely go out more than 10 miles for dolphin. When they are around you will usually find them closer in. Look for rips and eddys ,color changes,birds,boards,weed lines. Anything out of the ordinary.
Blackfin tuna are in closer. Try wrecks and reefs in the 120 to 200 foot depths.
There are no 120-200 ft depths on the gulf side that I know of 10 miles out. Where are you fishing?
