Hydros Large Arbor Fly Reels Take on the big game with the outstanding performance of our largearbor fly fishing reel. There is not another true large arbor, biggame flyfishing reel out there that carries this drag system performance. It's unheard of until now. The new Hydros Reel Series features a sealed drag surface that increases total drag surface by model: The larger the reel, the larger the drag surface and the more resistance available to handle larger fish. Using stacked carbon washers, controlled by a positive click adjustment system, the Hydros can be finetuned to handle any fish from a trout to a tuna with sustained and infinitely durable drag pressure. HYDROS IIIV have a four carbon washer drag system Multiplies retrieval rates Eliminates line coil New Mirageâstyle handle Color: Gold Note from Orvis: This reel has undergone a running change we modified the design in 2013 to minimize the issue of running line slipping through the line guard / spool interface. A reel with exceptionally tight tolerance is prone to rubbing under pressure. A slightly larger tolerance, as intended in the Hydros Large Arbor, allows for more operational clearance, but does allow running lines smaller than 0.029" to potentially slip through. For those using running lines less than 0.029" in diameter, please take this into consideration.
