Overview
A 500 meter (547 yard) spool of clear nylon monofilament fishing line rated around 6.7 kilograms of line weight, roughly in the 14 to 15 pound class.
The line weight is given in kilograms rather than pounds, converting to about 14.7 lb test, and the spool holds 500 meters, listed elsewhere in the data as 1640 feet. It is a clear colored monofilament suited to general spinning or casting spools rather than a specialty line.
- 500 meters (547 yards)
- About 14.7 lb test (6.7 kg)
- Clear color
- Nylon monofilament
Who it's for
Anglers who need a bulk clear monofilament refill in the mid teens pound test range for everyday spinning or casting reels. Not the choice for anyone needing a heavier saltwater class line or a low visibility fluorocarbon leader.
Strengths and trade-offs
Drawn from this product's published specifications.
- 500 meter spool covers multiple respools
- Mid teens pound test suits general freshwater use
- Clear color works across most conditions
- Line weight listed in kilograms requires a manual conversion to pounds
- Nylon monofilament only, no braid or fluorocarbon option
Performance notes
At roughly 14.7 lb test, this line sits in a versatile middle range for freshwater spinning and casting applications. Clear color keeps it usable across most water conditions without the added cost of specialty coatings or camouflage patterns.
