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 staff at Holohil is incredibly friendly and professional. I always go out of my way at conferences to stop by and talk with Fred and John, two great guys who are fun to talk to about transmitters, and life in general!

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 does go wrong with one of their transmitters, they replace it quickly and without question. John is extremely knowledgeable and really goes above and beyond in terms of customer service to understand the goals of my projects so that he can recommend the best product and/or possible modifications to fit my needs. I know I’m going to get the same great service whether I’m buying a single transmitter or 100.

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 projects. Both Fred and John are a pleasure to work with and chat with at the conferences. They show great knowledge of their products. John has been great to work with and planning an order with him has been a breeze.

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 configuration trade-offs. When something does go wrong (even if it is my fault – which it usually is), John and his team solve the problem right away. They have a customer for life.

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 and swamps . These transmitters are virtually indestructible – over the years, I’ve had units crushed by trucks and sliced by tractors and they still delivered strong, flawless signals, and I’m still using these units today!

But Holohil Systems, Ltd provides far more than just top-quality transmitters – their dedication to client-centered service is second-to-none. From troubleshooting and special orders to support and transmitter design, the staff at Holohil go above and beyond to provide a level of customer service that is simple unparalleled, and I view them as an integral part of my lab and its successes.
