• 10 Speed Multi-Speed Ratio for Various Fishing Situations: With 10 adjustable speed ratio (e.g. 5.1:1 to 8.1:1) you can choose the best winding speed according to your situation. The low speed ratio (5.1:1 to 6.1:1) is a durable battle against saltwater fishing big fish and is suitable for slow-attracting while increasing drag power; the high speed ratio (7.1:1 to 8.1:1) reduces the risk of rapidly winding up and escaping smaller fishes such as freshwater crawfish and minnow. The speed ratio switching can be operated with a single touch lever on the side of the reel, allowing you to quickly respond to emergency situations while fishing • STRONG MAGNETIC BRAKE REDUCES BACKLASH: Internal high magnetic braking system controls excessive rotation of the loop during casting, greatly reduces line tangling (backlash). Especially baitcasting reels make backlashes a challenge for beginners, but this magnetic brake provides increased stability while providing casting distance and allowing even first-time users to experience smoother casting. The brake force can be finely adjusted from 0 to 10 levels for optimal settings depending on wind strength or loop thickness • Super Drag Power and Maximum Drag Function for Overfish: The maximum drag force of 22.0 - 44.1 lbs (10 - 20 kg) (depending on the model), it allows you to control the large fish such as Thai, Marlin, Tuna and other big fish from saltwater fishing without cutting out. The drag adjustment knob is rubberized to prevent slipping, making it easy to fine-tune to the fish draw, reducing hand fatigue even for long periods of drag. In addition, the "Max Drag Lock" feature (some models) automatically activates a buffer when a load exceeds the set maximum drag force, preventing the loop from breaking by sudden force, so you can rest assured that you will win the game with big fish • Highly versatile for both saltwater and freshwater fishing: The salt-resistant metal body (e.g. aluminum alloy frame, stainless steel gear) is resistant to rust even when exposed to salt water for saltwater fishing, and maintains its performance over a long period of time. Meanwhile, the lightweight design (e.g. main body weight 8.8 - 12.8 oz (250 - 350 g) reduces burden for prolonged carrying and casting operation on freshwater fishing lakes and rivers. In long-distance rafts, motorized drives to easily rewind the loop over long distances, assist in wildlife fishing and the versatility of a single reel allows for multiple fishing styles • Electric Driven to Reduce Work Burden, Improve Durability: Powered by a built-in motor, it saves about 70% more force than manual winding and greatly reduces arm fatigue when pulling big fish, and physical exhaustion during long periods of fishing. Rechargeable lithium-ion battery (included) allows for 6-8 hours of continuous use (depending on usage conditions), making it suitable for long fishing trips. The internal gear adopts precision machined metal gears for abrasion resistance and long service life, and the electric motor is designed to minimize the noise effect on the fish while fishing, and maintain a natural fishing environment
