Sage Thermo Fly Reel // Heavy Duty Big Game 

It’s disorienting—there is no land, only sea and sky, and everywhere marlin blitz and tuna dive and mahi swarm weed patches. There are no beaches or mangroves to stop them, only you, a reel, and a piece of tippet that you can only pray will hold.

When entering the world of big game flats fishing and bluewater behemoths, heavy-duty is the name of the game. That lifetime tarpon, monster trevally, or massive shark could come into sight at any second, and for the angler hunting these big game fish, knowing your tackle can handle the fight is paramount. In steps the THERMO - heavy-duty in every sense. Designed to handle any tippet-busting, finger-cutting, hard-charging fish one may encounter. With the stopping power to keep a Giant Trevally out of the reef and the smoothness and endurance to outlast a blue marlin, the THERMO’s robust heat dissipating SCS drag, rigid frame, and burly feature set will have you covered like never before. The new leader in big game reel performance and reliability.

Starting with a new ultra-robust SCS drag package specifically built and tuned for the extreme, the THERMO delivers 0 to 20lbs of drag with unparalleled consistency of drag pressure throughout the entire run of the fish. No drop-off, skipping, or wear out because of overheating, the THERMO handles the extremes with ease, as the drag efficiently dissipates the heat across its fully sealed extra-large carbon brake discs. 20 easy-to-see drag settings sit atop a large-diameter drag knob that is incredibly easy to grip and adjust in the heat of a battle, while 39 detents allow for fine tuning adjustments for any leader and tippet combination.

The extra sturdy frame and spool are designed to hold up to the rigors of boat fishing where a knock on the gunwale or pounding run through breakers is not unusual. With a hefty large diameter ergonomic handle for maximum grip and control, and large arbor spool for quick pick up and 500+ yards backing capacity, the THERMO is the ultimate powerhouse of big game fishing reels.
