Unfortunately cabo is not fond of spearos, I went there last year and had no luck gettting a boat to go out on, and I have heard the same from others. I made a few beach dives at Santa maria bay, but other then that you have to east to go spearing. If you call mako spearguns, they are very nice and full of info, they might be able to point you into a direction of a panga you can rent in the area. Hope that helps.
