Seaweed net

The Seaweed net was released on 9 June 2009 and enabled an alternative method of collecting seaweed with up to 10 seaweed per net, therefore allowing a player to collect for much longer before needing to bank. Making the net requires a Crafting level of 52, and involves using 5 flax with a loom to create an unfinished seaweed net, then adding a bronze wire to complete the net. Crafting the nets only gives experience after adding the wire, which gives 83 xp. Seaweed nets can break at any time, and once broken they disappear. When the seaweed nets break, no seaweed is lost. Instead, it either ends up in the inventory or on the ground and can be easily put into another net. A player can have more than one net in their inventory at a time, so it is possible to collect 270 seaweed before banking, though this is unlikely as the nets break frequently. You can't have 28 nets in your inventory, because you need one space to "pick up the seaweed" - however, all you need to do is click on the seaweed on the ground; it then goes directly to your net without showing up in your inventory. A trick is to bring a beast of burden such as a spirit terrorbird or a war tortoise, and have them carry back-up seaweed nets so that when one in your inventory breaks, you can get a new one without banking.

Full Seaweed nets are not tradeable, therefore Beast of burden familiars are not able to hold filled seaweed nets, yet imp-in-a-box can transport them to the bank.

Function
When carried in inventory, if a player picks up seaweed, it automatically goes into the net. The same does not hold true when seaweed is caught through Fishing, you must left click the net to fill it.

It is a good idea to carry multiple nets because as mentioned before, they can break at any time.

To fill an Empty seaweed net manually, left-click it to "auto-fill" the net, similar to a vegetable sack. However unlike the vegetable sack it can be emptied by left-clicking the net. Note: Left-clicking partially-filled bags, with no seaweed in inventory, will answer "You have no seaweed with which to fill the net" Trivia
 * This item has recently been dubbed the "Gazinta bag" or "Gazbag" for short, named after the Australian spelling G'zinter, because of the way it works.
 * At June 16th 2009 the nets were updated to break less often.
