A lot of sites will give you thousands of reviews that say most products are great. I focus on a few pieces of gear that you really need for the different San Diego conditions and species that you’ll most likely be targeting. The main ocean fishing targets are shore angling, inshore (light-line, surface, bottom fishing) and offshore fishing (heavy or light tackle). Your gear will typically be different based on what you might be targeting. These are just general guidelines as the weather conditions, time of year, and species can make a huge difference. If you are going out on a San Diego Party Boat, call the day before to see what line/hooks/bait they will be using and plan accordingly. You can always rent gear on those types of trips, but its like a rental car, not really specific to what you may want, and barely maintained.
