There is a nice broken pier on Gasparilla Island / Boca Grande, and it is accessible from shore. The pier ends at like 500 feet and turns left to make an L shape. The depth there during a 4 foot high-tide is 20 feet deep and I dove there several times. Now I am thinking. Should I use a dive flag there? It isn't far from shore and boats normally don't come up to the pier. Like what is the rule of thumb when it comes to dive flags? Do you use them everywhere at all times? Or you need to use the dive flag only in certain situations such as when you are in the open ocean or when there is high boat-traffic?
