Our GS950 Hand Troll Gurdy system was designed with the smaller commercial fisherman in mind. This system gives you a manually controlled descent of the ball or weight, controlled by a simple turn of the handle. It is literally a one handed operation. If you get tired of cranking the handle while pulling in your big bounty, simply stop cranking and the handle stays put and will not spin or hit you. Our units are made out of stainless and anodized aluminum, with Timken bearings and automotive brake pads. These units were designed to handle the daily workload and were built to withstand the harsh conditions that come with fishing for a living.
