The Shearwater Research Swift GPS Transmitter is a compact and robust accessory designed for divers who require accurate surface positioning data integrated with their dive computers.

Constructed from high-grade, corrosion-resistant materials, the device features a durable polycarbonate shell and precision-machined metal components that withstand repeated exposure to saltwater, UV radiation, and physical impacts. Its sealed housing meets or exceeds IPX8 standards, ensuring reliable operation in demanding underwater environments. The transmitter employs a low-power, high-sensitivity GPS module that acquires satellite signals quickly and maintains stable connectivity even in challenging conditions such as rocky shorelines or heavy overcast skies.

Functionally, the Swift GPS Transmitter operates on a dedicated 1605 kHz frequency, providing seamless compatibility with Shearwater’s Teric, Peregrine, and Perdix series dive computers. Once powered on, it automatically searches for satellite signals and transmits real-time dive entry and exit coordinates, surface drift paths, and emergency location data via an onboard wireless link. This data is displayed directly on the dive computer’s screen as a simple waypoint or track, enabling precise navigation back to shore or a boat without requiring additional handheld devices. The transmitter’s low energy consumption allows for extended battery life—typically over 100 dives on a single set of common AA batteries—and the smart power management system prevents accidental activation during storage. The device’s compact footprint (roughly the size of a small flashlight) and lightweight design make it easy to attach securely to a BC, harness, or tank strap using the included stainless steel clip or optional screw-in mount. Its intuitive single-button interface simplifies pairing and status checks, while the bright LED indicator confirms satellite lock and data transmission status at a glance. For divers who venture into remote or crowded dive sites, the Swift GPS Transmitter offers a practical solution for maintaining situational awareness without adding significant bulk or complexity to their existing setup. Construction quality is a hallmark of this transmitter, with every unit undergoing individual calibration and rigorous environmental testing before shipment. The silicone rubber O‑rings and pressure‑equalization vents are designed for easy field replacement, extending the product’s service life. Despite its advanced functionality, the Swift GPS Transmitter is positioned as a very affordable enhancement for safety‑conscious divers—offering great value without compromising on reliability or performance. Because there is no price listed in the current catalog, potential buyers should consider this device a cost‑effective investment for any diver who wants to add precise location tracking to their gear. In summary, the Swift GPS Transmitter delivers dependable GPS logging in a rugged, user‑friendly package. Its straightforward operation, long‑lasting battery, and robust build make it suitable for recreational and technical divers alike, whether exploring familiar reefs or navigating complex currents. By focusing on core utility and durability, Shearwater Research has created a transmitter that meets real‑world demands with minimal maintenance overhead.
