Featuring the same hunting action as the previous RkCrawler, SPRO’s new RkCrawler 50DD can dive deeper than its predecessor in a smaller package. The RkCrawler 50DD is 50 mm long and weighs in at just 5/16oz oz. The newer model can dive 9-12 ft. deep. This crankbait is an efficient choice for deep water fishing in such a small model.
