The Australian Monitor LH25P is a highly-versatile 25-watt handheld loudhailer (megaphone) engineered for clarity and reach. With a pistol-grip handle design, it is lightweight (approx. 1.0 kg excluding batteries) and easy to operate, making it perfect for crowded or noisy environments. It incorporates a built-in tone generator offering fog horn, whistle and siren signals, enabling the user not only to speak clearly to large groups but also to issue attention-getting emergency or safety alerts. The LH25P runs on replaceable C-size batteries and can operate for up to approximately 6 hours of typical use, providing effective communication coverage of up to 400 metres under suitable conditions.
With its robust design and accessible form factor, the LH25P is ideal for event marshals, safety coordinators, sports coaches, educational environments, factory or warehouse supervisors, or any situation where a portable, powerful voice projector is required.
