Which magnets are suitable for geocaching?

We don't offer customised geocaching solutions, but we are happy to give you a few tips from our point of view as a magnet distributor.

Attaching caches magnetically

Attaching 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 neodymium magnets are not designed for outdoor use because they will eventually rust.

We offer a large selection of geocaching magnets.

According to our customers, a magnet must have the following features to fit into a micro (typically 3,2 x 4,5 cm).
1. Round and flat.

There is no one-size-fits-all solution. The first requirement is best fulfilled 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 bulge left over from the injection moulding 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.
2. A hole or indentation in the center

The second requirement is met by small countersunk disc magnets because they can be placed flush over the bulge left over from the injection moulding in the bottom of the canister. Ideally suited are the two magnets CS-S-15-04-N and CS-S-18-04-N. We recommend glueing the magnet to the bottom of the canister. It is very difficult to attach it to the round canister wall. Since not many adhesives hold reliably on plastic and magnets, attach the magnet with a strong adhesive tape.
If you choose to attach the magnet to the outside of the micro, you may use the following method. Our customer Thomas Mönkemeier came up with a sturdy solution that works well. He used round containers from the lab. These containers have the advantage that contrary to film containers they are water-proof. He attached the magnet to the outside with a heat shrink tube. To prevent the magnet from shifting during the shrinking, he put some adhesive tape under the magnet. He also used scissors to keep the magnet in place to avoid burning his fingers. Important: During the shrinking process, the temperature must not be higher than 80 degrees - otherwise the magnet will lose its magnetic force.
We recommend, therefore, to put the magnet on the inside of the micro to protect it from corrosion and blows.

Attaching small to large caches with magnets

For larger caches (small to large) you should affix 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.

Trade items inside the caches

Our magnets are great swag or trade items for larger caches that are not mounted with magnets. In addition to the colourful magnets listed below, you can find a wide variety of fridge magnets in our online shop.

Geocaching magnet

At a certain difficulty level, caches can also be found in tubes. There is no other way to get to the cache but to "fish" for it with a magnet. Therefore, our customer Nandi gave his nephew (who is a passionate geocacher) a magnet for his treasure hunt.
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 metalworker 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 rope.

If you don't want to go through all this trouble, you can order strong fishing magnets from our online shop. More manageable and lighter is our telescopic magnet lifter:
