I am very surprised to read there are people throwing their used baits overboard. Everyone I know throws them in the bottom of the boat and they blow out on the way home. Seriously, throw them on the floor and pick them up after you get the batteries on charge. Wow.
On another note, I was reading about a bait made by Jackall. It described the bait as being made from Edum. Then it had a line that said.
About EDUM: The material will dissolve into "water" and "carbon dioxide" within a short period of time (30-60 days).
