Responsive, comprehensive assistance to meet your specific tracking needs.
Holohil Systems has spent over 35 years redefining the standard for wildlife tracking and telemetry. We know well that the wildlife research community requires consistently reliable equipment that produces precise data. We also know that wildlife researchers are not necessarily experts on VHF transmitters and related tracking equipment. That is why we pride ourselves on providing responsive, comprehensive assistance to the scientists who use our equipment. We make sure their questions and concerns are addressed immediately and we will develop custom solutions where needed. It is also why we put every piece of equipment we produce through a rigorous quality control process and guarantee that we will repair or replace any transmitter that malfunctions or operates at less than peak performance. We are proud that we can assist the crucial work of wildlife scientists and it is a responsibility we take seriously.
Working with Holohil was easy!
We got our products on time and all functioning perfectly. Folks at Holohil were always responsive, happy to answer questions, etc. Could not have asked for better.
Great products, great company, extremely responsive customer service!
Thank you so much for all your help and support for our projects over the past few decades!
My favorite thing about Holohil is that calling customer service is like calling a friend!
Someone answers within the first few rings… no “dial this number for sales”, no voicemail… It is a person every time (usually John :)) who has all the answers to my questions.
The best radios.
We have put RI-2B radios on over 70 turtles in different parts of Mexico. We have lost a couple of turtles that walked out of our field site, we have had turtles that were predated by a jaguar or puma, we have even had turtles die during an extreme drought, but we have never lost a turtle due to radio… Read more “The best radios.”
Transmitter signal strength is absolutely incredible!
These transmitters have not disappointed and continue to impress! I ordered Holohil RI-2D (with a mortality sensor) transmitters per my advisor’s suggestion for my graduate research on small mammal and Burmese python interactions in the Greater Everglades Ecosystem. We’ve attached them to cotton rats to look at cause-specific mortality and survival in areas with pythons compared to areas without pythons.… Read more “Transmitter signal strength is absolutely incredible!”
Everyone at HOLOHIL is
Everyone at HOLOHIL is extremely friendly and helpful. Their transmitters are always delivered on time (if not early) and the batteries often last well beyond the expected lifespan. I have used HOLOHIL with snakes, birds, and turtles and have always been 100% satisfied with the experience and the product. Thank you HOLOHIL!
Horned lizard research greatly enhanced by transmitter longevity
I’ve been using radio telemetry in field research with lizards, snakes and tortoises for over 20 years. My experience with Holohil over the past ten has been simply amazing. The longevity of tags, allowing us to reduce impacts through capture and tag replacement, has far exceeded all expectations. In particular, we only recently documented the extreme duration of the hibernation… Read more “Horned lizard research greatly enhanced by transmitter longevity”
Transmitters Exceed Expectations
I have been thoroughly impressed with the quality and longevity of Holohil’s transmitters! The transmitters are well-designed and very durable, even despite blazing heat, below freezing temperatures, and degradation from acidic swamp habitats. The battery life has been reliable and often far exceeded the estimated life. Several transmitters estimated to last 6 months were still signalling 12 months later! The… Read more “Transmitters Exceed Expectations”
We’re batty for Holohil!
In the consulting business, you don’t always know what you need for a project, or even how many projects will require telemetry! We rely on Holohil to provide the best quality radio-transmitters for tracking small bats in the eastern US and the best customer service. Our business-to-business relationship with Holohil is superior to any other, and we are able to… Read more “We’re batty for Holohil!”
Thanks a million to the Holohil team for providing such excellent transmitters!
Barbastelles and wind power – a project to improve knowledge and provide guide lines. The world is a dangerous place for bats. One serious threat in Europe and elsewhere is the wind turbine industry, which is growing fast.
The research was focused on the western barbastelle (Barbastella barbastellus), a rare and threatened insectivorous bat suspected to be vulnerable at… Read more “Thanks a million to the Holohil team for providing such excellent transmitters!”
Holohil is simply the best
I have been conducting radio telemetry facilitated research on snakes since the early 1980’s. During that time, I have used transmitters produced by several manufacturers, encountering many problems along the way. In 1997, I changed to Holohil transmitters and I’ve never looked back. Holohil is clearly top of the line, and they stand behind their products no matter what. The… Read more “Holohil is simply the best”
I will never buy transmitters from anywhere but Holohil!
The product quality and customer service they offer cannot be matched by any other company. I can depend on their transmitters to perform better than promised even in harsh environmental conditions. Battery life typically exceeds the advertised life span so I never have to worry about losing study animals to early transmitter failure. In the extremely rare event that something… Read more “I will never buy transmitters from anywhere but Holohil!”
It’s Holohil or nothing!
I’ve used Holohil transmitters for my snakes for 10 years, and would never consider switching to a different company. They provide a high quality product at a fair price and will customize your order. Their customer service is top notch. Having met several of the staff, they all treat you like family and genuinely care about you and your research!
Using Holohil transmitters is a no-brainer
The stellar service and quality of product provided by Holohil just simply cannot be beaten. I find the ease with which I can communicate technical specifications and shipping complexities remarkable.
Superior Quality Transmitters
I have used HOLOHIL transmitters for many of my projects over the years. We first used them for our spatial studies of Eastern Massasaugas and found their implantable transmitters to be far superior compared to other manufacturers. We were so impressed with the longevity of their transmitters we have since used them on our Blanding’s Turtle and Alligator Snapping Turtle… Read more “Superior Quality Transmitters”
There’s simply no need to look anywhere else for your telemetry needs!
Our organization has worked with Holohil, mostly through John Edwards, for years now and for good reason: John and the entire Holohil team have never disappointed us. They consistently offer friendly, professional service and their products have never faltered. And the extra swag is of course always welcomed.
Amazing service and reliability
I’ve been ordering from Holohil since 1997. Whether my orders are large or small, I’ve always been impressed with the quality, reliability, and turn-around time of the transmitters. The units are well-designed, hold up to everything from raptors to snakes to turtles, and last as long or longer than quoted. I can always rely on great advice for attachment and… Read more “Amazing service and reliability”
I wouldn’t trust my data – or my turtles – to anyone but Holohil!
When my research hinges on reliable telemetric data, I rely on transmitters from Holohil Systems, Ltd. Durable and dependable with a long battery life (WAY longer than promised), Holohil transmitters deliver reliable data year in and year out in the most challenging of tracking environments, from the urban environs of the concrete jungle, to blistering deserts, to remote bottomland forests… Read more “I wouldn’t trust my data – or my turtles – to anyone but Holohil!”
