Firetacks are a great way to make a night cache. They are low tech and low maintenance. The following tutorial will identify some things you should consider when using FireTacks.
The first thing you should do is make sure the area you are placing the FireTacks is accessible at night. Many municipal parks are closed at dusk. Look for signs at the trail-head to find the information you need.
FireTacks use a retroreflective material. This means that the light shown at the firetack will be reflected back to the SOURCE of the light. For this reason headlamps are recommended. When using a headlamp your eyes will follow the beam of light. The FireTacks may not appear as bright to someone standing next to the person with the light. If you are using handheld flash light hold it to your eye level. When placing your FireTacks pay attention to the area around the tree you are using. Are there likely to be trees or bushes that grow up in front of the fire tack you have placed? FireTacks should be placed at about eye level to minimize the issue of new growth.
The retroreflective nature of FireTacks combined with the diameter of the tree they are placed on create a natural blind spot behind the FireTack. It is important to remember this when placing FireTacks in the bush. The searcher can follow the FireTacks in to the cache but what do they follow to be back to the trail? It is very easy to get turned around in dense foliage when searching for a cache. If you are using flat trail reflectors you should place one on each side of the tree. One for the way in and one for the way out. This safety procedure means you will need more markers if you are using flat reflectors.
With FireTack reflective trail markers you can place the marker perpendicular to the direction of travel. In this way you can see the same reflector on the way in and on the way out. When placing a complicated cache it is always a good idea to have someone test your geocache placement before it is published. I have had to amend several cache placements based on tester feedback. Keep in mind there is still a blind spot behind the FireTack. If your path to the cache turns you may have to augment your egress path with additional FireTacks.
Variation One – Counting FireTacks
There is more than one way to lay out a FireTack trail. The most common is just lay out the FireTacks exactly where you want to lead the cacher. A slight variation on this type of cache is where you count the number of FireTacks you see and at a certain number you turn or do something different. Another way to approach this type of cache is have the cacher go until there are no more FireTacks and then count back a small number. At that point is where the cacher turns in.
In this example the cache location is marked by a different color FireTack. You can use colors to mean different things.
The fact that you aren’t sure where you are going or if you’ve seen all the FireTacks makes this kind of night cache fun. There is something about feeling a little lost in the woods, at night, that heightens the excitement.
Variation Two – Pattern Change
An alternative to making geocachers count FireTacks which is not as easy as it sounds. Night Caching in the rain or the winter tends to inhibit one’s ability to accurately take notes. Using a pattern change is a good way to tell cachers that you expect them to do something different.
As with the previous example extending the FireTacks past the turn off point adds a little more complexity to the cache, from the searcher’s point of view.
How far apart should you place your FireTacks? There is no easy answer for this. FireTacks are visible from hundreds of meters when using a bright LED light. In practice the effective distance is much lower because of obstructions. Trees, branches and leaves all play a part in making your FireTacks harder to see. You should place the reflectors far enough apart that the searcher has to be on the look out for them but not so far apart that a small branch will obscure the view. In the real use you can expect to place FireTacks every 40-80 meters. This is another example of why having someone that didn’t help you place the FireTacks should test your cache before it is published. Feedback from the trial will allow you to add more reflectors if required.
Variation Three – Color Change
You can take advantage of the fact that FireTacks come in multiple colors to introduce some complexity into your reflector trail. Different colors may mean change in direction (that might include looking behind you),
You could also create two paths using different colored FireTacks. One path could be a red herring and the other is the target path. Adding a color hint to the cache description would let the cacher know which path to take.
The examples provided in this tutorial are a starting point. Expand on these ideas to create a unique cache that other geocachers will enjoy finding.
Firetacks are made of durable materials and will work for many years. Mother Nature has a way of reclaiming her turf and some firetacks will go missing. While FireTacks are a low maintenance way to build a night cache you should expect to replace about 10% of the FireTacks each year.
