Great learning Compass
Bill from VA
We bought 60 of these and they all worked well. Air filled so they need to be held still but for the price they are great.
Tracy from Colorado
Just what I ordered! Came promptly and all of them worked.
Demonstrating a magnetic field
Jearl Walker from Cleveland State University
Putting a bunch of these small compasses around a bar magnet reveals the magnetic field lines.
Seabee Six from Manns Choice, PA
Good quality for the money. One of the ten ordered pointed South, but it didn't matter as used.
Julianne from Salt Lake City, Utah
This small compass is just what we needed for our unit on magnets. It's easy to read and fairly accurate. I wouldn't try using it if you become lost in the woods, but as a student piece it's just fine.
