Does this reel come pre-chalked or do I need to fill it first?

The reservoir is empty when it arrives — you'll need to add chalk powder before your first layout. Fill it, snap a line to saturate the cord, then you're ready to work.

How accurate is the built-in level?

It's a standard bubble level integrated into the reel housing. Use it as a quick reference for minor adjustments, but always verify critical panels with a dedicated level for precision work.

Can I use this reel with different chalk colors?

Yes — empty the reservoir completely and rinse it out before loading a different color. Blue won't contaminate white or red if you clean between refills, but residue can tint the next color slightly.
