Supply Signal

You hate someone? Throw these into their base.
You want action, throw it somewhere close by.
You want distract people from the helicopter, throw this one.
You hate everyone, grap some ladders, get some diving suite and climb up a ice block in the water, where no one lives. Throw it there and get sniped.

Solo tip, grab a boat and get far away from land throw it in the water but dont forget that the airdrop will sink so grab diving gear

You probably don't want to signal an airdrop onto your base because it causes you to get raided.

Be careful if you decide to throw the supply signal, as other people will come and possibly raid you if they see the supply drop falling in the air or if they see the purple smoke.

The icon of the Supply Signal shows a purple stripe on the bottom of the canister, on the model spawned when thrown this isn't present as it is the same as the normal smoke grenade.

If you play solo and want to drop a supply signal very far from coast to be as safe as possible, NEVER, NEVER get past 15 grids from X grid. The boat will despawn and you will instantly die to cold.
