Global annual sales are projected to reach several thousand units by 2025. Product pricing depends on factors such as frequency range, sensitivity, depth, and application scenarios, with prices ranging from $500 to $2000. The industry's gross profit margin is in the range of 30%–45%.

As global competition for marine resources intensifies, high-sensitivity, wide-bandwidth hydrophones with in-situ digital capabilities have become a core competitive advantage in the market. The industry focus is shifting from single sensor manufacturing to acoustic sensing system integration, particularly driven by MEMS piezoelectric technology. Miniaturized, low-power hydrophone arrays will gradually replace traditional, bulky sonar elements, becoming fundamental nodes in the deep-sea Internet of Things.
