Is the spool worth it if I already own a Behemoth?

Yes, if you fish more than one line. A spare spool lets you switch from floating to sinking line in seconds without re-rigging. At $79.99 it is cheaper than a second reel.

Does it fit my Behemoth reel?

It fits the Behemoth 5/6 reel. The spool is sized for 5 and 6 weight lines and about 125 m of 20 lb backing, so check your reel's size before buying.

Can I change it to left-hand retrieve?

Yes. The retrieve converts between right and left hand, so it matches whichever side your reel is set up for.

How much backing does it hold?

About 125 m of 20 lb backing, plus your fly line. That is enough for most trout and bass situations.

What comes in the box?

The spool and a nylon reel case. The reel frame, drag knob and line are not included.

Spare spools rarely get deep discounts. Watch for sales at Amazon and fly shops around spring and holiday promotions; the current best new price is $79.99 at Amazon as of November 4, 2026.
