Fishing is not expensive. For a couple of hundred euros you can buy some nice equipment. You will have a fishing rod, line, and lead fishing weights, a few floats and a scoop net. A little lure and we can start fishing.
Successful fishing starts with the preparation at home. Clean your fishing material every time you come home after fishing. Take the right equipment for every circumstance; different fishing locations have different water conditions (depth, bottom, lure etc.). Also the weather conditions can differ (wind, rain). When you are prepared for conditions like these, you are a step ahead on your competitors.
