Intelligent Digital Control braking system allows anglers to fine-tune their reel to the perfect setting for each line/lure combination, achieving trouble-free and enhanced casting distance. I-DC5 has two sets of dial adjustments. With the inside dial, anglers can select the type of fishing line being used: Nylon Monofilament (N), Fluorocarbon (F) or Braided Line (PE). The outside dial adjustment is based on the lure type: 1. Big Lures (5/8 to 1 oz) with low air resistance, 2. Medium Lures (3/8 to 3/4 oz), 3. Small Lures (1/4 to 7/16 oz) with high air resistance or 4. Finesse Lures (3/16 to 1/4 oz). The final setting is the ‘AUTO’ function (A), letting the onboard DC decide the optimal brake setting. The I-DC5 braking system uses more magnets to assist braking compared to the previous systems. With the addition of a ring magnet, brake force can be applied more evenly and increases the maximum spool revolution by 12% at the start of a cast.
