Compass

Compass points at the world spawn — the coordinates the world was generated around — and not at your bed. That distinction costs people their first base: sleeping changes where you respawn, but it does not change where a Compass points, so a needle that looks wrong is usually right about a place you have stopped caring about.

Binding fixes that. Use a Compass on a placed lodestone and it locks onto that block instead, keeps pointing at it from any distance, and takes on an enchantment shimmer so a bound one is easy to tell apart. A lodestone compass also works in the Nether and the End when its lodestone is placed there, which an ordinary one does not — outside the Overworld the plain needle spins at random, and a bound one starts spinning again if its lodestone is broken or left in another dimension.

It does its job without being held. A Compass reads correctly in your inventory, in your off hand, or hung in an item frame on a wall, where it becomes a fixed arrow pointing home. In Bedrock Edition a map only shows your position marker if a Compass went into making it, so a plain map crafted without one will never tell you where you are standing.

The recovery compass is the same idea aimed elsewhere: rather than spawn or a lodestone, it tracks wherever you last died, and it spins blank if you have not died yet or if your body is in another dimension. Between the two, late-game navigation is mostly a handful of bound compasses in item frames and one in the hotbar for the trip back to whatever went wrong.
