HOLOHIL

Choosing the right transmitter settings is all about your study priorities...

🔋 Longer Lifespan – Maximize battery life for longer deployments.

📡 Stronger Signal – Improve detection in dense vegetation, rugged terrain, or when greater tracking range is needed.

🔔 Faster Pulse Rate – More frequent beeps make animals easier to locate and track.

Each setting offers advantages, but optimizing one typically means making trade-offs with the others. If you don't have a specific priority, our standard tuning provides a balanced combination of lifespan, signal strength, and pulse rate for reliable all-around performance.

Meet Ember the hawk! 🦅

This magnificent hawk is wearing a Holohil BD-2 transmitter, captured by one of our longtime falconry customers. We love seeing our equipment in action alongside such incredible birds.

Come stop by our booth at the SEPARC conference held in Black Mountain in North Carolina! Make sure to say hi to our representative Mike Legare, who can answer any questions you may have. 🐸🐍

Kind words like these mean the world to our team 💚

At Holohil, we believe great customer service should feel personal, helpful, and human. We’re always happy to help support the important work our researchers do every day.

Thank you, Alicia, for your thoughtful feedback!

This blind mole rat is fitted with a PD-2C collared transmitter — a popular choice for tracking small to medium mammals and rodents. Lightweight and reliable, collars like these help researchers monitor movement, habitat use, and behavior in the field. 🐀

When reviewing transmitter specifications on our website, you may notice both 'Standard Lifespan' and 'Potential Lifespan' listed. So... what's the difference?

Standard Lifespan is the expected battery life under typical operating conditions, using standard factory tuning with balanced signal strength and pulse rate settings. 🔋

Potential Lifespan is the maximum battery life that may be achieved by reducing signal strength, slowing the pulse rate, and incorporating duty-cycling schedules. ⏳

The best configuration depends on your study requirements, including range, tracking frequency, and desired battery life.

A big thank you to Taggert for sharing his experience! 🐢📡

We’re thrilled to support your turtle research and are glad our transmitters can assist you in the field. From demanding conditions to unforgettable wildlife moments, it means a lot to know our technology is helping power your work.

We're always excited to see the real-world impact that wildlife telemetry can have on conservation efforts 🐢

This incredible episode by , highlights the work researchers and biologists are doing to help preserve the Mojave desert tortoise, and we're proud that Holohil transmitters can play a small part in supporting this important work.

It's also so nice to see some familiar faces! Several of the researchers featured in the episode are longtime Holohil customers, making it even more rewarding to see the important work they've been doing with our transmitters in the field. 🙌

The dedication and innovation behind these conservation efforts are truly inspiring. Be sure to check it out here: https://youtu.be/pSgLBWrlQJ4?si=TBC2NaEoh4w0mdKM
