Megaphones

Our range of megaphones carries a voice much further than shouting ever will, which is why they are standard kit for marshals, coaches, site supervisors and event stewards. Most run on ordinary batteries and several add a siren or a record function for repeating the same announcement. Found it cheaper elsewhere? We will match the price.

How far will a megaphone carry?

Manufacturers quote a maximum range in metres, and like any such figure it assumes still air and an open space. In practice wind, traffic and a crowd all cut it down, so a unit quoted at 500 metres is realistic across a sports field but will do far less along a busy road. If you need to reach a large area, two smaller megaphones used from different positions usually beat one large one shouted from the middle.

Power ratings and what they mean

Output is given in watts, and the useful range runs from around 8W for a school sports day up to 45W and beyond for marshalling large events or working on a noisy site. Watts do not translate directly into loudness, since the horn design matters just as much, but within a single range a higher figure will reach further. For most schools, clubs and small events, 15W to 25W is the sensible middle ground.

Siren, whistle and record functions

A siren cuts through noise far better than speech, which makes it useful for starting a race, clearing a route or getting attention before an announcement. A record function stores a short message and repeats it, which saves your voice at a car park entrance or a queue. If either matters to you, check it before buying, because the cheaper models often have speech only.

Handheld or shoulder strap

A pistol grip is quick to raise and fine for short bursts. If you will be using it across a whole event, look for a shoulder strap and a separate handheld microphone, which lets you carry the horn at your side and speak without holding it up. Detachable microphones also make it easier to use the megaphone from a vehicle or a fixed position.

Batteries and running costs

Most megaphones take standard C or D cells, which is convenient but adds up if the unit is used weekly. Rechargeable cells pay for themselves quickly in that case. Battery life is quoted in hours of intermittent use, so continuous announcing will drain them considerably faster. Always carry a spare set, since a megaphone that fades halfway through an event is no use at all.

Getting the clearest speech

Hold the microphone close and speak across it rather than into it, keeping your voice level and slower than usual. Short phrases carry much better than long sentences, and pausing between them lets the sound decay so the next words are not muddied. Point the horn slightly above the heads of the crowd rather than straight at the nearest person, and never aim it at anyone at close range.

Frequently Asked Questions

How far will a megaphone carry?
Quoted ranges assume still air and open space, so wind, traffic and crowds reduce it in practice. A unit rated at 500 metres will cover a sports field but far less along a busy road. For large areas, two smaller units in different positions work better than one large one.

What wattage do I need?
Around 8W suits a school sports day, 15W to 25W covers most clubs and small events, and 45W or more suits large events and noisy sites. Horn design matters as much as watts, but within one range a higher figure reaches further.

What is the record function for?
It stores a short message and repeats it, which saves your voice at a car park entrance, a queue or a route closure. Not every model has it, and cheaper units are often speech only, so check before buying.

Do megaphones have a siren?
Many do. A siren cuts through background noise far better than speech, so it is useful for starting a race, clearing a route or getting attention before you speak. Check the specification, as it is not universal.

What batteries do they use?
Most take standard C or D cells. Rechargeable cells are worth it if the megaphone is used weekly. Quoted battery life assumes intermittent use, so continuous announcing drains them faster. Carry a spare set.

How do I get the clearest sound?
Hold the microphone close and speak across it rather than into it, in short phrases and slightly slower than normal. Pause between phrases so the sound decays. Aim the horn just above the heads of the crowd, never at anyone close by.
