Shimano Ocea Conquest reels are specifically designed for inshore fishing from boat, mostly for vertical jigging. This Ocea version Conquest reels have power handles to crank much heavier rigs than freshwater fishing. Spools are narrowed from original Conquest for its purpose. Level widners are engaged to spools to move while dropping rigs or lines are pulled(only for 300/301). Level winder of 200 models are disengaging for faster rig dropping. Side plate drilled holes on original Conquest are saved to prevent saltwater gets inside unnecessary. Brake is not variable from outside as this is not mainly aimed at casting, but the reel still have the 4point brake for 200 models, and you may change the brake setting by opening side plate. 300 models doesn't have spool brake, and it is only for dropping rigs from boat.
