The whole product is plastic, so won't corrode, and the line is both positively buoyant to avoid snagging, and fluorescent orange of easy visibility.

Small and light enough to fit in a stab jacket pocket so it's there if you need it.

Annoyingly it's just too big to post as a "large letter" so has to go as a parcel, but I'm happy to combine postage for multiple items (any other dive gear I have listed), just select 'collect in person' for additional purchases and leave me a message at checkout.
