Hallo, my December holiday I spent in Sierra Leone. Google the place and you will realize there's not much info and almost nothing about spearfishing. The travel was hard and I decided against the speedboat approuch (well don't have enough money), between hiking and kayaking I finally reached my destination and started scouting for spearfishing spots. Long story short I found a good spot after 7 days went into the water shot a few nice fish. And then I shot a nice 15kg+ fish, it went into a shipwreck (secret spot) and I lost my spear. Holiday ended with extreme dissappointment, mad at myself and all the rest.
I think there's loads of fish the viz is not great and I could not find 1 reef, with that said, if you go in season (August, September, November) you might get some Tarpon, I saw 1 and almost fell on my back. I will not shoot that with my 90cm gun.
Love to hear from people thats done spearfishing in Sierra Leone, I'm going back in December with more heavy dutie equipment.
