40 -
41 -**Protection**: Place nodes inside thick, landfill biodegradable plastic bags for environmental protection.
42 -
43 -**Site Analysis**:
44 -
45 -* Conduct compass measurements away from the node and metallic structures, adjusting for inclination angle.
46 -* Take multiple photographs from various angles to document the site setup thoroughly.
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)
48 -
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.

81 -
82 -=== **6- Data Sharing and Metadata Creation** ===
83 -
84 -**GPS Data**:
85 -
86 -* Download the GPS file to a laptop.
87 -* Share this file on a drive accessible to all team members for uniform understanding of node locations.
88 -
89 -**Photo Sharing**:
90 -
91 -* Upload site photos to a shared platform (OneDrive, Dropbox, etc.).
92 -* Integrating photos into Google Maps or Google Earth can be particularly beneficial for easy location referencing.
93 -
94 -**Metadata File**:
95 -
96 -* Create a metadata XML file for each node, which is essential for data organisation and future reference.
97 -
98 -=== **7- Additional Best Practices** ===
99 -
100 -* **Environmental Responsibility**: Ensure that the node placement and the materials used are environmentally responsible and adhere to local regulations.
101 -* **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.
