FAQ - Frequently Asked Questions
Which magnets are suitable for geocaching?
We don't offer customised geocaching solutions, but here are a few tips:
Fastening caches magnetically
Fastening micros magnetically
Many geocachers would like to use magnets to attach micros (small film canisters containing a log book and pen) under bridges, guard rails or other metal hiding spots.
Please keep in mind that magnets are not designed for outdoor use because they will eventually rust.

Therefore it is important to protect the magnets well if they are attached to the outside of the micro.
There is a detailed customer application
(available only in German) on this topic.
We recommend, however, to put the magnet on the inside of the micro to protect it from corrosion and blows.
According to our customers, a magnet must have the following features to fit into a micro (typically 3,2 x 4,5 cm):
- round and flat, so it doesn't take up too much space in the already tiny film canister
- bore hole or depression in the center, to fit over the little hump on the bottom of the canister and lie flush against the bottom.
disc holds a film canister and three pens in place with no problem.
Small and flat strong magnets
There is no one-size-fits-all solution.
The first requirement is best fulfiled by our discs S-10-03-N
They are so small that they can be glued next to the hump in the bottom of the canister.
As an alternative, you can use strong adhesive tape to attach them to the side wall of the canister.
Magnets with a whole or cavity
The second requirement is met by small countersunk disc magnets because they can be placed flush over the hump on the bottom of the canister.
We recommend gluing the magnet to the bottom of the canister.
It is very difficult to attach it to the round canister wall.
Since not many adhesives are dependable on plastic and magnets, attach the magnet with a strong adhesive tape.
Fasten small to large caches with magnets
For larger caches (small to large) you should attach several magnets on the inside of the canister.
Depending on the size, weight and thickness of the cache, flat discs or block magnets are suitable.
Magnets for attaching lighter caches
Magnets for attaching heavy caches
Bartering objects in caches
Magnets are good bartering objects for larger caches that are not attached to anything with magnets.
We recommend small neodymium magnets in their original packaging (plastic bag), since this protects them from corrosion.
