微型化深水设计
采用小型化流线型设计,直径仅25毫米,空气中重量0.56千克,最大限度减少对载体设备的影响。

MMA-7500 is a deep-water, compact, lightweight self-contained ARGOS positioning beacon in the NOVATECH series, belonging to the new Mini Beacon product line. This beacon adopts a titanium alloy shell, with a pressure resistance depth of 7500 meters, designed specifically for long-term marine asset recovery. The device is controlled for start and stop through an internal magnetic switch and integrates a conductive sensor to achieve a fully automatic activation mechanism. Powered by lithium batteries, the MMA-7500 can support underwater deployment for up to 2 years and continuously transmit ARGOS positioning data messages for up to 90 days after surfacing, making it an ideal choice for deep-sea equipment tracking and recovery.
