Popper fishing at La Zona can produce huge dorado exceeding 50 lbs. The key to finding a great popper is it must have a shallow cup mouth and be lightweight yet heavy enough to make long casts. The shallow cup mouth allows the popper to be retrieved at very high speeds yet putting out enough splash to trigger strikes. Long casts next to boulders are the best bet for hooking into a giant. In Argentina, Juan Vaccaneo, owner of the CANO company makes the best poppers for La Zona. These cedar poppers come in grande ( 16cm, 75gr) and medianos (12cm, 42gr). The CANO poppers are the perfect size as casts can be make accurately and without wearing one out while reeling as fast as hell! In triggering dorado one does not "pop" as popper. They come in multiple colors of which I have found makes no difference.
So, next visit to La Zona or other freshwater dorado destinations make sure to add CANO and Klure poppers to your tacklebox!
***as of this writing, due to the high cost of cedar in Argentina, CANO poppers will not be produced out of wood, but will be created out of polyurethane. Hopefully the wood costs decrease so these amazing poppers can once again be made.
