FAQ - Frequently Asked Questions
Which magnets are suitable for geocaching?
Fastening caches magnetically
Fastening micros magneticallyMany 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 neodymium magnets are not designed for outdoor use because they will eventually rust.
There is no one-size-fits-all solution. The first requirement is best fulfiled by our disc magnets S-10-03-N, S-10-04-N or S-10-05-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.
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. Ideally suited are the two magnets CS-S-15-04-N and CS-S-18-04-N. 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 magnetsFor 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.
Bartering objects in cachesMagnets 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.
For that purpose, he ordered THE GIANT from us. Since the magnet by itself is rather unwieldy, he built a steel casing for it. He went to a metal worker who fabricated the casing for him. The magnet is now embedded in epoxy resin in this steel casing and can be moved with a mountaineering cord.
