Lightweight and the power to stop big fish. Not a sentence you are used to hearing! Seemingly against the laws of nature. Thunnus takes a page from our Bicycle division using Carbon materials in high impact situations. Thunnus CI4 is a response to all the anglers out there in love with the ease of use and functionality that wanted the reel to shed some weight. Thunnus CI4 is up to 7 ounces lighter than its predecessor without sacrificing any power. Quite the opposite!! Due to new drag systems for the Main Drag and the Baitrunner drag Thunnus CI4 is the most efficient live bait spinning reel on the market with unmatched adjustability for fishing any bait in any condition as well as the smooth stopping power that this generation of Thunnus will be known for.

great offshore reel
Bought this with a loomis pro blue, use it in south florida for live baiting dolphin and tarpon. Handles the tarpon under the bridges in excess of 100 lbs and is great for drifting live bait offshore with the bait runner feature. it overmatches the schoolie dolphin but easily handles the larger gaffers. I would buy 10 more if they didn't update the models every few years making parts to previous models obsolete. I have a dozen shimano reels (more?) and take care of them. when they finally need parts, you can't get them a few years after they come out. Good news is if you take care of them, you can give them to your kids. Smooth and strong, good drag and love the bait runner feature. kids can put it in the rod holder and walk they do, turn the crank and your fish is still on and they do not have to adjust the drag, just crank in your fish. I use it more than my stellas because they are several generations old and can't afford to have them break. not much of a drop off in performance.
Conseventually parts will not be available as newer generations of this reel come out

Super Easy
Used this reel for fly-lining Sardines and the bait-runner feature worked well. Caught some nice 20-30 Yellowtail and drag worked great. The clicking feature of the bait-runner is annoying, but does a great job of keeping just enough pressure to keep your line sung. it was especially helpful on a full boat with others getting all tangled up. I used the bait-runner on its lowest setting the entire time and it was fine for the larger sardines I was using, but for smaller anchovies I think the drag might me a little too much.
ProsEasy to cast, holds plenty of line, bait-runner feature, smooth drag, , as fool proof as it gets, great for my wife
ConsIts a spinning reel, so you feel a little wimpy

Best Reel for the Money!
I'd purchased a Thunnus C14 8000 about a year earlier for striper fishing and loved it, but wanted to go one size up for my annual Florida tarpon trips. The Thunnus 12000 "filled the bill" perfectly. Rugged, reliable and for what it's worth, a perfect match for my Shimano Telavera spinning rod. I'd never owned a "bait runner" reel before, now I wonder how I ever lived without one. I'm already planning to buy a second one!

Pricey but worth it.
I use this mostly for saltwater bottom fishing (in Rhode Island), but will throw a plug on if the bluefish are around (they are fun to catch). Fished with this reel 8 straight days on the saltwater and don't see any signs of corrosion anywhere on the reel (I did give it a freshwater wash down after every trip). Casts great, and the retrieve is very smooth. So far the biggest fish I have caught was an 8 Lb. bluefish and a 6 lb. skate (but hope to get some bigger ones in the future).
ProsVery smooth Casts great

I Have several baitrunners dating back to the 4500A 16 years ago, which still works.... This is the best yet, the power grip is a great improvement and the infinite anti reverse is awesome.
ProsShimano Baitrunner super smooth infinite anti-reverse power grip
Consnot too crazy about the color, its like blue metalic. I would like to see like a brushed or satin silver finish and of course nothing ever wrong with black or charcoal

Great drag system
I paired the reel with a med Terez rod. Makes a perfect setup for larger fish. Great Tarpon and Cobia setup. Super drag system. Love the live bait feature. Comfortable large handle. Own several 8000 and 12000.
ProsDrag system
ConsSeems to be over rated on .40 line capacity. Have never been able to get more then 275 yards as compared to rating of 320.

Best Spinning Reel
Been switching my reels from Baitcasters to Thunnus's. All in all I am really a huge fan of both. I have the older Baitcaster that have the metal frame verse the Composite that is used in the Thunnus. The 12000\8000 Thunnus does still have some Metal in the Frame. This is the only downside to the Thunnus that I have hit so far. One of the reels I received the composite base was broken and I had to return for a replacement. This makes me worry about the long term durability of the new Thunnus. This does make reels much lighter, though. Time will have to be my judge on if the composite holds up as well as the metal for the older Baitcasters. As of now I am extremely happy with the reel and transition.
ProsEvery feature under the sun!
ConsLess metal and more composite.

Ocean Going Spinning Reel
It is beautiful, smooth, tough and your not going to do any better than this for a big spinning reel. I love the freespool lever.
ProsYou can cast jigs or bait care free with spot on accuracy. Retrieves line back fast and it is a blast catching big fish on a spinning reel.
ConsEvery cast puts a twist in the line. You cannot put the pole on the rail. The flouro topshots have a tendency to unravel off the spool.

Awesome Reels
I love these reels! High quality as always from Shimano. Smooth drag and great baitrunner feature. I love these reels for surf fishing because I can set the reel on my rod holder, flick on the baitrunner switch and I don't have to worry about leaving the bail open or loosening up my main drag. Once a fish is on, turn the handle and the reel automatically switches from baitrunner mode to fighting mode. This allows me to set my main drag and not have to mess with it again.
ProsHigh quality, great looks, smooth drag

Best baitrunner reels
I purchased Thunnus 6000 to pair with my star rod Paraflex 10'. It is by far the smoothest reel I ever used. I learned through hard knocks with other live liners reels. Please do yourself a favor and skip other live liner reels and buy the shimano baitrunner. You get what you pay for.. Smooth, great casting and dependable reels. I have caught 40 inch Stripers off the pier with breeze. Highly recommend! I just wished I got the 8000.

I have an 11' Avid surf rod that I will be using a lot on the Outer Banks, NC, which Thunnus would you recommend...
1 Answers
You could get by with the 8000 size and not have to go with the huge 12000. However this would probably be my last choice of reel for this application. Check out the Ultegra from Shimano.

What would be the best rod for the 4000 model ?
1 Answers
A medium to medium heavy rod in the 7'-8' range would fit that reel very well. The "best rod" depends on what you are fishing for and what method you use.

Is this reel made in Japan?
1 Answers
Product of Malaysia. I have been fishing the 8000 and 12000's for a year now for white marlin and sail fish. the quality has done nothing but astonish me. they are ultra light with very smooth drags. What i like most is how quickly and securely it will shift from bait mode to your primary drag, a big improvement from the last generation.

What is the difference between this reel and the bait runner other than $100.00 I need to buy (4)
1 Answers
The Thunnus CI4 reels are lighter than the Baitrunners, since the frame and rotor on the Thunnus reels are made of CI4 material and the Baitrunner's frame is made of graphite. The Thunnus is a lighter, stronger version of the Baitrunner.
