许多爱好野钓的钓友,大概都遇到过这种情况:由于天气预报不准,我们骑自行车跑十几公里处去钓鱼,想不到钓着钓着,天突然刮起了五六级大风,整个水面波浪滚滚,两只手连竿都稳不住。鱼不能钓了,想回家吧,偏又遇顶头风,连推着自行车走都困难,没办法,只好无可奈何地干熬着,等风小下来。要是这时知道鱼儿躲在哪儿,把竿伸过去,岂不是一件大快事! Many fishing enthusiasts who love fishing, probably have encountered such a situation: due to the weather forecast is not allowed, we run a bike to run a dozen kilometers to go fishing, can not think of fishing to catch the day suddenly scalped 56 winds, The entire surface of the water billowing, both hands are not stable even rod. Fish can not catch, want to go home, partial encounter the head wind, and even pushing the bicycle are difficult to walk, no way, had nothing to do with the dry, wait for the wind down. If this time to know where the fish hiding, stretched out the rod, would not it be a big deal!
