Hi
If you are there, you may try http://www.fishpanamatoday.com/
I hope it will be fine. I never tried them but I heard good things about them: they do spearfishing trips too even though they don´t advertise it too much.
Have fun

Hello! I am visiting Boca Chica, Panama from 12/27 - 12/31 and am REALLY dying to go spearfishing both Inshore and hopefully Offshore on 12/29 or 12/30 or both days. I have found very little luck finding a charter that does spearfishing, do you know anyone or do you have friends that would be looking for one dive partner who can pay for gas etc? 1-424-333-6080
