20 ft. Braided Line + Suspension Hook
Ships with 240 in. of low-stretch braided line and a steel S-hook at the anchor end. Extra 16 oz. mass on 20 ft. of drop steadies the line in wind where a lighter bob sways. Line coils inside the body under the removable cap for compact storage.
16 oz. Solid Brass
Double the heft of the 8 oz. brass bob. The extra weight steadies the line in wind and on long drops where a lighter bob sways.
Hardened Steel Tip
Hardened steel point reads the mark cleanly on softwood, hardwood, and concrete. Brass tips go dull after years of use; this one stays sharp.
2 Replacement Tips Included
Ships with two threaded steel spare tips. Swap a fresh point when the working tip wears or chips on stone, no shopping for a one-off replacement.
