Lobstering middle Keys - 22 Sep, 2019

I have been hunting for lobster many years while staying on Cudjoe Key. We have always gone to the bay side and dove the passes. It was slim pickings this year. I have never tried diving on the Atlantic side and to be clear, I'm not asking for numbers but what do you look for? On the Bay side we look for ledges and holes. For those who dive on the Atlantic side, what do you look for and at what depth are you looking?
