27 -
28 -* Station name
29 -* Latitude and longitude
30 -* Names of team members present
31 -* Date and local time of installation
32 -* Serial number (SN) of the sensor

36 -)))
37 -
38 -**Protection**: Place nodes inside thick, landfill biodegradable plastic bags for environmental protection.
39 -
40 -**Site Analysis**:
41 -
42 -* Conduct compass measurements away from the node and metallic structures, adjusting for inclination angle.
43 -* Take multiple photographs from various angles to document the site setup thoroughly.
44 -* 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)

46 -=== **3- GPS Considerations** ===
47 -
48 -(% class="wikigeneratedid" %)
49 -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.

51 -=== **4- Visibility and Location Marking** ===
52 -
53 -**Flag Placement**: Position a flag, preferably in a bright color (avoid green or yellow), near the instrument to aid in its future location.
54 -
55 -**GPS Marking**:
56 -
57 -* Use a GPS device to mark the instrument's exact location.
58 -* Record this location in both your paper notes and the GPS device.

61 -
62 -* **Charging Duration**: Both types of nodes take approximately 6-8 hours to fully charge from a flat state.
63 -* **Pre-Deployment Charging**:
64 -** Although the nodes hold their charge well, it's beneficial to give them a "top up" charge right before deployment.
65 -
66 -* **Operational Duration**:
67 -** When recording at 250 Hz, with GPS on and Bluetooth disabled, the instruments are expected to last about 30 days per charge cycle.
68 -
69 -* **Post-Retrieval Charging**:
70 -** Do not store the instruments with completely drained batteries.
71 -** After retrieval, charge the instruments to about 50-60% (indicated as "orange" level) for optimal battery health.
72 -
73 -* **Storage and Shipping Charge Level**:
74 -** Maintain a battery charge level of around 50-60% for both storage and shipping purposes.
75 -** This charge level is recommended to prevent battery damage and is safe for transportation.

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

106 -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.
