Tips on How to Use the Shimano Thunnus Ci4

The Shimano Thunnus Ci4 may appear overwhelming if you’re new to fishing. But with these pointers, you’ll be able to utilize it expertly in no time!

  1. First and foremost, make sure that your reel is properly spooled with line. If done incorrectly, this is one of the most crucial components of utilizing any reel and can cause major issues while fishing.
  1. Attach your reel to your rod once it is spooled and ready to go. Once more, making sure that everything is securely fastened can spare you a lot of trouble in the future.
  1. Now it’s time to start fishing! Begin by casting your line out into the water, then use the handle on the reel to slowly bring it back in. It’s important to keep a steady pace while doing this, as reeling too quickly can cause problems.
  1. If you feel a fish biting on your line, begin reeling it in faster so that you can set the hook and land your catch!
  1. Once you’ve landed your fish (or if you’ve decided to give up for the day), simply wind your line back onto the reel using the handle. Be sure to do this slowly and carefully so that no line gets tangled or damaged in the process.

That being said, here are a few recommendations for Paladin gear:

  • If you’re looking for more damage output, the Excalibur and Wyvern Shield are good options.
  • And if you’re looking for more defensive capabilities, the Platinum Sword and Diamond Shield are worth considering.
  • It’s ultimately up to you to choose the gear that complements your Paladin build the best. But no matter what you decide, always remain focused and keep your eyes on the goal!

Waterproof drag with Dartainium II cross-carbon washers 

When it comes to fishing reels, one of the most important features is water resistance. That’s why the Shimano Thunnus Ci uses Dartainium II cross-carbon washers for a waterproof drag system. This means that you can fish in all kinds of weather and not worry about your reel getting wet or damaged.

The Dartainium II cross-carbon washers also make for smoother drag, so you can fine-tune your settings and get just the right amount of resistance. This is a great feature for both novice and experienced anglers alike.

Front and Rear Baitrunner Drag

Shimano’s Thunnus CI is an incredible reel that provides amazing front and rear drag. The reel’s smooth, powerful drag system and 14 bearings make it one of the best baitrunner-type reels on the market.

Baitrunner drag systems allow for easy adjustment of the amount of drag on your reel. This is especially helpful when targeting big fish, as you can easily adjust the drag to accommodate the fish’s weight and fighting style. The Shimano Thunnus Ci baitrunner drag system is composed of two parts: the front drag and the rear drag. The front drag is designed to be lighter so that it doesn’t impede the movement of your bait, while the rear drag provides more resistance to help slow down fleeing fish.

Six shielded A-RB ball bearings

The Shimano Thunnus Ci comes with six shielded A-RB ball bearings, which are designed to provide smooth operation and long-lasting durability. The bearings are also resistant to corrosion, making them ideal for use in saltwater environments.
