size matters
The World's Smallest Transmitters
Sure, in some cases bigger is better...but don't go trying to sell that to French Olympic pole vaulter, Anthony Ammirati 🍆 ! Sometimes the best things come in the smallest packages, and that's how we feel about this selection of our tiniest transmitters. Whether you're looking for GPS quality positions in a package that doesn't require recapture or manual download, or you work with a species so small it can only carry something as light as a grain of rice, we at CTT have you covered. All of our units are made right here in Cape May, New Jersey, from the point of conception, to the point where you take delivery.
The Lightest GPS/Cellular Transmitter
The FlickerGPS brings best-in-class telemetry to animals that can carry 3 or more grams, opening the door to thousands of new species. From fully-potted units that are fully submersible to waif-like backpacks for large songbirds and small raptors, the FlickerGPS continues to deliver novel data on many species of conservation concern.
BlūBat
The smallest-in-class battery-only digitally-coded transmitter (2.4 GHz) for species that require transmission in the dark or at night. Great for bats, birds, rodents, and more!
BlūMorpho
The BlūMorpho tag is the lightest-weight radio tracking tag on the market, weighing in at 60 milligrams. That is 0.06 grams—less than a grain of rice.
The BlūMorpho tag is ideal for very small birds, butterflies, bees, and other insects.
This tag's 100% solar, no-battery design means no worries about battery life—these small-but-mighty tags can transmit indefinitely!
