A common sight in Havana Cuba, fishing off the Malecon (sea wall).
The Malecon as a entry point is easier to get to for Havana residents, but normally it's slim pickings.
A wood speargun is very unusual to see in Cuba. Band spearguns are rare in general. Cuba is the land of the pneumatic speargun, usually homemade.
The following pic is typical of parts of the northern coastline. High cliffs with deep water close by. My favorite place to dive and we had to climb down those cliffs and lower the gear with a rope. At other spots you had to throw the gear in the water and jump in from a height of approx 30'. I used to have pics of my water entry from just such a place and pics from the top of the cliff of the speargun floats disappearing in the distance.
