Product Description

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.

Size: 12000
Having had such strong performance with the Thunnus 6000, I decided to add the Thunnus 12000 to my collection. I am very pleased.

The 12000 holds about 550 yards (maybe more) of 30 pound test fireline. This capacity is needed when I catch a monster shark or game fish - they love to run!

I use my reel in the surf at Seabrook Island, South Carolina (A private island that offers great surf fishing -- you can rent an ocean front villa for a great price!) It gets splashed with the salt water, and keeps on going! I always use the baitrunner feature.

I did own a Van Staal for a few months, I traded up for the Thunnus, and saved a bunch of money in the process. I also own a Thunnus 6000, and I notice that the 12000 gives me longer cast. It also seems to be a bit more smoother on the retrieve.

Towards the end of the season, my 6000 was completely summerged in the sandy surf water and the gears started to grind. For the low price of $24, Shimano serviced it. It is like brand new! With a strong company that is ready to service this excellent reel, I see this being an easy 5 star rating.

Bottom line - a great reel that is backed by a great company. The service is wonderful and reasonably priced. The drag and strength of this reel will enable you to bring in the monsters of the sea!

This is the 'baby' Thunnus. I bought it because it is reasonably lightweight yet gives me good line capacity. I use it with a medium weight 7-foot Cabela Saltstriker rod for stripers and blues in Long Island Sound. I've spooled it with 30-lb braid and fish with a 5-foot fluorocarbon 25-lb-test leader. It's got an exceptionally smooth drag and the oversized handle makes for an easy retrieve. It won't wear you out after a long day of casting. I like the combo because it's extremely sensitive; I have lots of fun fighting fish in the 2 to 12 lb category but it gives me confidence that I can handle something much bigger. The bait-running feature is interesting but I haven't had a chance to give it a fair test yet since 95 pc of my fishing is with artificials.

These reels are bullet proof. Have 5 of these I use for the Gulf of Mexico surf (Texas side)....Have caught bull reds up to 48 inches and sharks up to 5 feet on these reels and they have more than enough line to handle the Gulf surf fish. Drag system is very smooth. With a 4 ounce lead/leader, these reels (with a 12 ft surf rod) can put the bait out over 100 yards.

I was deciding this or the Shimano Baitrunner and super glad i went with this one. I paired this up with the tsunami airwave and it is by far the best rod and reel combo i have ever owned. The Thunnus is super smooth in casting and reeling. Caught my first salmon on this and it was a smooth and fun fight all the way through.

I purchased this unit in November 2004. It had a tough year as I use this reel to surf fish in South Carolina. I use it with 30 pound test fireline. I always use the baitrunner feature.

This is simply the best surf reel on the market. (I did own a Van Staal for a few months, and traded it in for the Thunnus.)

With this reel, I landed a 4 foot shark and a 6 foot manta ray on the beach. The drag held togther. The reel gets plenty of splashes from the surf, it holds up well.

Towards the end of the season, it was completely summerged in the sandy surf water and the gears started to grind. For the low price of $24, Shimano serviced it. It is like brand new!

My one complaint - I need a lot more line. These large fish will take the hook and run. Even with the very small diameter of the fireline, the 6000 is a bit small. I now plan to use the 6000 as my backup reel, and I purchased a Thunnus 12000 for my primary. It holds about 550 yards of 30 pound fireline!

Bottom line - a great reel that is backed by a great company. The service is wonderful and reasonably priced. The drag and strength of this reel will enable you to bring in the monsters of the sea! (Just be careful to understand your line requirements)

This is an amazing live-bait reel.
Totally exceeds all expectations.
The 6000 Baitrunner is also excellent which I also have and convinced me to spend the extra for this all ball-bearing light-weight model.
If you like live-bait fishing this is the best of all reels.

Everything looks fine. Filled up with Power Pro braided 40lb and managed to put in 300m of line. Next is to put it into action.
