There are many different types of traps available on the market. However, Crotrap is unique in its shape and features, and there is nothing like it. It is a clover-shaped fishing rod that its manufacturer Dario Marinov named Crotrap. Since he also has his own fishing trade, designing this tool that will serve both professionals and amateurs was not a problem for him. Crotrap is characterized by a unique shape and, as Marinov claims, the fact that there are no defects that appear with similar tools. The existing tools on the market have some disadvantages, an inefficient shape that confuses the fish so it cannot find its way into the tip, a size that prevents quick manipulation and work with a larger number of traps, and also unnecessarily takes up space on the boat, a complicated design that requires a lot of material, but also time, which makes the product more expensive, and many are even improperly made, which puts fishermen at risk of misdemeanor charges. As he says, the tools that can most often be found on the market are not adapted to today's way of fishing and cannot cope with the needs and legislation of modern fishing. This is precisely why he decided to make a tool that he would use himself, and he emphasizes that he worked on the development of the idea for several years, but he successfully achieved his goal and created a tool that will have a perspective in professional fishing.
