47 +* Include a detailed site description in your notes, specifying distances and orientations from nearby landmarks (e.g. Richards garden, Te Mini steam field eastern side)

49 +=== **3- GPS Considerations** ===
50 +
51 +(% class="wikigeneratedid" %)
52 +The GPS antenna is at the top and center of the unit, and will (usually) only receive signal with a clear sky view directly above. The signal is able to penetrate plastic and terracotta planters and a thin layer of soil, but may struggle if the soil layer is too thick. The BD3C will not start recording without first attaining a GPS lock.
53 +
54 +=== **4- Visibility and Location Marking** ===
55 +
56 +**Flag Placement**: Position a flag, preferably in a bright color (avoid green or yellow), near the instrument to aid in its future location.
57 +
58 +**GPS Marking**:
59 +
60 +* Use a GPS device to mark the instrument's exact location.
61 +* Record this location in both your paper notes and the GPS device.

64 +
65 +* **Charging Duration**: Both types of nodes take approximately 6-8 hours to fully charge from a flat state.
66 +* **Pre-Deployment Charging**:
67 +** Although the nodes hold their charge well, it's beneficial to give them a "top up" charge right before deployment.
68 +
69 +* **Operational Duration**:
70 +** When recording at 250 Hz, with GPS on and Bluetooth disabled, the instruments are expected to last about 30 days per charge cycle.
71 +
72 +* **Post-Retrieval Charging**:
73 +** Do not store the instruments with completely drained batteries.
74 +** After retrieval, charge the instruments to about 50-60% (indicated as "orange" level) for optimal battery health.
75 +
76 +* **Storage and Shipping Charge Level**:
77 +** Maintain a battery charge level of around 50-60% for both storage and shipping purposes.
78 +** This charge level is recommended to prevent battery damage and is safe for transportation.

84 +=== **6- Data Sharing and Metadata Creation** ===
85 +
86 +**GPS Data**:
87 +
88 +* Download the GPS file to a laptop.
89 +* Share this file on a drive accessible to all team members for uniform understanding of node locations.
90 +
91 +**Photo Sharing**:
92 +
93 +* Upload site photos to a shared platform (OneDrive, Dropbox, etc.).
94 +* Integrating photos into Google Maps or Google Earth can be particularly beneficial for easy location referencing.
95 +
96 +**Metadata File**:
97 +
98 +* Create a metadata XML file for each node, which is essential for data organisation and future reference.
99 +
100 +=== **7- Additional Best Practices** ===
101 +
102 +* **Environmental Responsibility**: Ensure that the node placement and the materials used are environmentally responsible and adhere to local regulations.
103 +* **Training and Familiarisation**: Make sure all team members are adequately trained in using the GPS devices, compass, and other equipment to ensure consistent and accurate data collection.

109 +Use a (**landfill**, not //compost//) degradable bag when installing to keep the instrument clean. This will save you many hours of time cleaning them in preparation for their return. [[Here is a video>>url:http://auspass.edu.au/field/bd3c_removal.mp4]] demonstrating its effectiveness.
