There is a shop called OPSIMAS near to the Essencia Hotel which has a decent amount of fishing tackle. 30 metres south of the hotel, same side of the road on the highway.
"ZEBCO SPECIAL"? I like those "ZEBCO SPECIAL" also. When I get pissed off and throw it in the ocean I'm not out a lot of pesos. I got my first Zebco as a teenager (14) and a bunch more over the last 57 years. Caught a lot of fish over those years with them also.
