Stand up rods were originally designed for the West-Coast-giant-yellowfin fishery. These long-range anglers needed sturdy rods that could both handle the abuse a 300 lb. tuna dishes out and succesfully land the beast. This series started around 7 ft. in length and has gradually grown shorter as anglers realized that longer rods transfer more pressure back onto the fisherman. With the innovation of TC4 Construction and proven actions, Shimano has developed the ultimate line of Tallus Stand Up rods designed to stop the baddest yellowfin tuna in their circles. The end result? You catch more fish.
