👁️Two-throw Stronghold Triangulator
Combine two Eye of Ender flight directions to estimate where their forward paths cross in the Overworld.
Enter both readings to calculate an estimated crossing.
Quality is based on both your movement baseline and the angle between throws.
💡 How to use:
- Record Overworld X/Z and F3 yaw while looking along the Eye path.
- Move a meaningful lateral baseline, preferably 100+ blocks sideways.
- Take the second X/Z and yaw reading along the new Eye path.
- Travel to the estimated X/Z and verify with another throw.

Travel with fewer detours
Plan portal links before placing obsidian
The Nether compresses horizontal distance. Convert the destination first, then inspect terrain on both sides before committing a permanent portal room.
Edition & scope note
The 8:1 horizontal scale is shared by modern Java and Bedrock play, while exact portal search and linking behavior has edition-specific details.
- 01
Enter X and Z
Portal conversion uses the horizontal axes. Keep Y as a separate terrain and safety decision.
- 02
Confirm the direction
Overworld to Nether divides X/Z by eight; Nether to Overworld multiplies them by eight.
- 03
Build with linking tolerance in mind
Nearby portals can compete for a link, so verify both endpoints instead of relying on rounded coordinates alone.
