Airmar EchoRange

The Airmar EchoRange is a compact marine sonar and depth-finding transducer designed for vessel navigation, obstacle detection, and seabed mapping across shallow to moderate water depths. The transducer emits acoustic pulses and measures return time to calculate water depth and identify submerged objects — logs, rocks, wrecks — that pose collision hazards to surface navigation.

Operating specifications on the EchoRange typically cover frequency ranges around 192kHz or 235kHz in the ultrasonic band, providing fine range resolution suitable for detecting objects as small as 15cm to 30cm depending on transducer model. Range coverage extends from near-field dead zones of 0.3 to 0.5 metres up to maximum detection ranges of 60 to 150 metres depending on water clarity and seabed composition. The transducer mounts through-hull or on a transom bracket, with electrical connections via a single-pin or multi-pin connector to a compatible marine GPS/fish-finder display unit or standalone depth gauge.

Transducer construction uses high-grade piezoelectric ceramic elements in a corrosion-resistant stainless steel housing, rated for continuous freshwater and saltwater immersion. Typical transducer weight is between 200g and 800g depending on mounting style, with no moving parts to require maintenance or replacement.

In Pakistan, the Airmar EchoRange serves Pakistan Navy patrol craft, commercial fishing vessels operating along the Karachi and Gwadar coastlines, inland waterway navigation on the Indus River system, and private marine vessels across coastal Sindh and Balochistan.

Tactical Supply Pakistan stocks Airmar EchoRange transducers and compatible marine display integration for naval, commercial, and private maritime navigation applications across Pakistani waters.
