Geocaching Honor

Recreational Activities

Requirements

  1. Define geocaching.

    Answer: A worldwide treasure hunt via GPS: caches (containers with a logbook) listed online with coordinates. Participants locate them and record their visit; started in 2000 in the USA, with 3 million+ active caches. — Created in 2000 when President Clinton released high-precision civilian GPS (removing Selective Availability). The first cache was by Dave Ulmer in Beavercreek, Oregon. The community generates 'logs' (records) with date and nickname. It differs from letterboxing (no GPS) and Munzee (QR codes). It teaches navigation.

  2. What is a GPS receiver?

    Answer: Um receptor GPS é um aparelho eletrônico que capta os sinais de rádio emitidos pelos satélites do sistema GPS (Global Positioning System). Ao receber o sinal de pelo menos 4 satélites, ele calcula a distância até cada um (pelo tempo que o sinal levou para chegar) e, por triangulação/trilateração, determina a posição do usuário na Terra: latitude, longitude e altitude, com precisão de alguns metros. Existem receptores dedicados (GPS de mão usados em trilhas e geocaching) e também embutidos em smartphones e carros. O sistema completo tem cerca de 24 a 31 satélites orbitando a Terra a aproximadamente 20.200 km de altitude. — An American system operational since 1995. Others exist: GLONASS (Russia), Galileo (EU), BeiDou (China), GNSS (multi-system). Civilian receivers post-2000 have an accuracy of 3 m (without Selective Availability). DGPS (Differential) reaches centimeters. Garmin is a historic manufacturer (1989).

  3. Demonstrate two ways to find the location of a cache in your area on the geocaching site ( http://www.geocaching.com/. Note: the site is in English, but you can find the necessary information at the site: http://www.geocachingbrasil.com.br/).

    Answer: 1) By GC code (the unique ID of each cache — direct search in the bar). 2) By address/zip code or by browsing the interactive map. Filters by difficulty, terrain, size, or cache type. — Official site groundspeak.com (owner of the Geocaching brand). The API allows apps such as c:geo (Android, free) and Cachly (iOS, paid). The map uses the Google Maps API with its own layer of points. Important filters: 'My Finds' excludes those already found; 'D/T 1/1' are easy ones for beginners.

  4. Demonstrate how to enter latitude and longitude coordinates into the GPS device to locate a cache in your area.

    Answer: Access the 'Mark Waypoint' or 'Find Coordinate' menu. Enter in the DD MM.MMM' format (degrees/decimal minutes) — the Geocaching standard: e.g., N 23 32.456 W 46 38.123. Save it with a name (GCxxxxx). Start 'Go To', which shows the distance and a directional arrow to the point. — The Garmin eTrex (main line) and a smartphone with c:geo accept coordinates. Formats: DD.dddddd° (decimal); DDMM.mmm' (geocaching); DDMMSS.s" (sexagesimal). Brazil is in the southern (S) and western (W) hemisphere. Display accuracy of 5-15 m outside the dense urban environment. WAAS/EGNOS improves it to 3 m.

  5. Define the following terms
    • Traditional cache
    • Micro-cache
    • Virtual cache
    • Multi-cache
    • Travel bug

    Answer: 1) Traditional cache: a container with a logbook and, usually, small trinkets for trading. 2) Micro-cache: a tiny container that holds only the logbook, with no room for trinkets. 3) Virtual cache: has no physical container; the goal is to visit and observe a specific place, usually by answering a question to prove the visit. 4) Multi-caches: a cache with several stages, where each point provides clues or coordinates that lead to the next, until you reach the final container. 5) Travel bug: a trackable item (with an ID tag) that travels from cache to cache, carried by participants, and whose route can be followed online. — Official types: Traditional (most common), Multi, Mystery/Puzzle, Letterbox Hybrid, Event, EarthCache, Wherigo, Virtual (rare). The Travel Bug is a registered trademark of Groundspeak — a metal tag with a unique number. There are also Geocoins (custom coins) that travel the same way. Nano-caches hide in a magnet under a bench.

  6. What items can be left in a cache? What items cannot?

    Answer: Allowed: small toys, geocoins, foreign coins, photos, stickers. Prohibited: food (attracts wildlife), scented items, drugs, weapons, large amounts of money, liquids, and live animals. — Geocaching.com has clear rules (Cache Listing Guidelines): nothing that could cause harm, attract wildlife, or be illegal. Fast-food toys are classics. Geocoins travel between countries like Travel Bugs. Items prohibited in Brazil follow the penal code: weapons (Law 10,826), drugs (Law 11,343).

  7. Know and practice etiquette rules regarding Travel Bugs.

    Answer: Take the TB to another cache within 2 weeks, register it online on the same day (Grab/Drop), respect the destination indicated by the owner, and never keep the item or trade it for another. Do not take a TB out of the country without authorization. — TBs have a 'mission' — visit country X, photograph landmark Y. Hijacking (theft) is a serious problem: lost TBs amount to ~30% according to Groundspeak. The online logbook has 'Retrieve from cache' and 'Drop in cache' buttons. Each move adds km to the bug's public journey.

  8. Search for three caches in your area; at least one of them must be a traditional cache.

    Answer: Choose 3 caches on geocaching.com — 1 traditional (T 1.5/D 1.5 for a beginner) + 2 free choice (multi, virtual, or others). Enter the coordinates into the GPS, go to the location, find the container, sign the physical logbook, and register 'Found It' online on the same day. — A beginner should start with T (terrain) and D (difficulty) ≤ 2. Caches in urban parks or on bike paths are easier. Bring a pen (a wet logbook smudges), a spare GPS/cell phone, glasses, and a flashlight. Always put the cache back exactly where you found it for the next geocacher.

  9. Write about your found cache in your logbook on the Geocaching site ( http://www.geocaching.com/).

    Answer: Valuable logs describe the route, environment, and curiosities without spoiling the exact location. 'TFTC' (Thanks For The Cache) is a standard greeting. 'TFTH' = Thanks For The Hide. The CO receives an email notification. Rude logs or those that reveal the location can be deleted by the CO.

  10. Discuss Matthew 6:19-21 and Jeremiah 29:13 and then compare them with the practice of geocaching.

    Answer: Mt 6:19-21: 'Do not store up treasures on earth... where your treasure is, there your heart will be also.' Jer 29:13: 'You will seek me and find me when you seek me with all your heart.' Geocaching illustrates the sincere search for something eternal. — Mt 6:21 teaches that the heart follows the treasure. Jer 29:13 is in the context of the Babylonian exile — God's promise to those who seek with all their heart. Lesson: the effort to find a cache (hours, maps, patience) should also be directed toward eternal things. A typical reflection in an Adventist youth devotional.

  11. Discuss safety issues you should consider when practicing geocaching.

    Answer: Go with company, tell others your destination, take water, a snack, a flashlight, a cell phone, and repellent. Respect the wildlife/flora, do not trespass on private property. Beware of snakes, bees, and unstable terrain. — Geocaching has terrains from T1 (accessible) to T5 (extreme, requiring climbing). The most common accidents: ankle sprain, fall, insect bite. Always download an offline map. In urban areas, watch out for social dangers. Caches on railways and abandoned tunnels are prohibited by Groundspeak due to lethal risk.
