For researchers documenting wildlife in northern latitudes or high-altitude alpine zones, the Followit Tellus is the most reliable choice for overcoming the thermal limitations of traditional hardware.

How to Choose the Right GPS or VHF Tracking Tech

Selecting the right technology depends entirely on the resolution of data required versus the logistical reality of the field site. GPS/satellite collars are essential for mapping large ranges and studying behaviors in remote areas, but they require a higher budget and carry more weight. VHF transmitters, conversely, are lighter and cheaper but require the researcher to be within a specific distance to capture the signal.

Consider the “Data-to-Weight” ratio during the initial design phase of the study. A heavy, data-rich collar may provide excellent information but could negatively impact the natural movement of the subject, leading to biased results. Always evaluate the trade-off between the depth of information and the welfare of the animal before finalizing a hardware selection.

Sizing Collars Safely for Animal Comfort and Care

The physical fit of a collar is the most important factor in maintaining animal health and project integrity. An ill-fitted collar can lead to chafing, tissue damage, or, in the worst cases, restrict the animal’s ability to forage or socialize. Ensure the collar leaves enough room for muscle expansion and natural movement, while remaining snug enough to prevent it from snagging on external obstacles.

Standard practice dictates that the collar should be able to rotate slightly around the neck without sliding off. Always consult with veterinary experts or experienced field biologists regarding species-specific sizing guidelines, as neck anatomy varies drastically across mammals. Never prioritize data collection over the physical well-being of the specimen.

Maximizing Battery Life During Remote Field Studies

Battery depletion is the most common reason for premature study failure. To mitigate this, implement a “duty cycle” that adjusts the frequency of GPS fixes based on the animal’s expected activity periods. For example, programming a higher frequency of location pings during active hunting hours and reducing them during known rest periods can double or triple the total operational life of the unit.

Utilize onboard solar panels if the animal lives in an open-canopy environment, as this can offset daily power consumption significantly. However, remember that forest cover and dense brush will render solar panels ineffective. In such cases, opt for high-capacity primary batteries that are specifically rated for the temperature range of the study area to avoid unexpected power death.

Retrieving and Maintaining Your Collars Post-Study

Planning for retrieval is just as important as the deployment itself. If the collar does not have a programmed remote-drop mechanism, ensure that the study design accounts for the physical recovery of the hardware. Many researchers use timed release mechanisms or biological degradation materials to drop the collar automatically, which eliminates the need to recapture the animal.

Once recovered, the maintenance process should begin immediately to preserve the data and the hardware. Clean the housing of mud, salt, or organic debris and inspect the seals for any signs of moisture ingress. Even if the collar is not meant for reuse, extracting the raw data logs directly from the internal memory is a crucial step for verifying accuracy against the satellite transmissions.

By investing in the right tracking technology and respecting the needs of the animal, researchers can turn complex field challenges into clear, actionable data. Stay focused on the integrity of the work and the safety of the wildlife, and the insights gathered will inevitably contribute to a deeper understanding of our natural world. Good luck with the field season.
