A game reel is basically built up like a multiplier reel, but of much more robust construction.
They all have a spool in a strong frame, centered between two side plates.
Most modern trolling reels are designed with an variable lever drag system
with the maximum setting pre-set to suit the line being used.
This allows quick and easy changes to the drag during use
and allows the setting to be returned to the original setting after the fish is landed.
Some reels have two speed gearboxes making it easier to fight
stubborn and deep fighting fish like big Tuna and Shark.
Gear changing is instantaneous using a control on the reel handle.
Furthermore all trolling reels are designed with a very loud ratchet,
informing the angler and crew when a strike occurs.
Shimano TRN is a light game reel with star drag mechanism.
It features a heavy-duty level wind anti-jam mechanism,
a strong aluminum spool, strike alarm, main and pinion gears
plus a power knob and handle.
