How to Choose the Right Tour Guide System for Your Group Size

Buying or hiring a tour guide system is a straightforward process — once you know what to look for. The most common mistake people make is focusing on price first and finding out too late that the system doesn't fit their group, their environment, or their schedule.

This guide walks you through the key factors to consider, with group size as the starting point.

Start with your group size

Everything else flows from this. The number of participants in your group determines how many receivers you need, what kind of charging solution makes sense, and how much you should budget.

Small groups (2–10 people) For intimate tours, almost any system will work well. You have plenty of flexibility on range, charging, and cost. A basic 1-way system with a 12-slot charging bag is typically all you need.

Medium groups (11–30 people) This is the most common range for guided tours. You'll want to think carefully about receiver count, battery life (can you get through a full day on one charge?), and how easy the system is to distribute and collect at the start and end of a session.

Large groups (30–100+ people) At this scale, logistics matter as much as audio quality. You need a system with a large enough charging solution to power all devices overnight, a transmitter with good range, and receivers that are robust enough to handle heavy daily use.

Transmission range

Tour guide systems are typically rated for ranges between 30 metres and 150 metres. The right range depends entirely on where you're running your tours.

30m range — suitable for indoor use in relatively contained spaces: small museums, showrooms, offices, and factory floors where participants stay close together.

100m range — the most versatile option, covering the majority of indoor and outdoor tour environments. A good default if you're unsure.

150m range — for large open outdoor spaces, big industrial sites, or anywhere participants might spread out over a wide area.

One thing to note: walls, machinery, and other obstacles can reduce effective range. If you're touring in a complex indoor environment, go for a system with more range than you think you need.

Battery life

Most modern tour guide systems offer up to 20 hours of battery life on a full charge. For a typical 2–4 hour tour, this is more than adequate. But if you run back-to-back tours throughout the day, you need to think about your charging strategy.

Key questions to ask:

• How many hours of tours do you run per day?
• Do you have time to recharge between sessions?
• Are you running tours on consecutive days without a break for charging?

If you run intensive multi-day tours, look for a system where all devices can charge simultaneously overnight — which brings us to charging bags.

Choosing the right charging solution

A charging bag or case is what keeps your entire system powered up between uses. Getting the right size is important.

12-slot charging bags are ideal for small to medium groups. Compact, easy to transport, and quick to set up.

35-slot charging bags are designed for larger operations — conferences, big group tours, or organisations running multiple sessions simultaneously.

If your group is larger than 35 devices, you may need multiple charging bags. Factor this into your budget and logistics planning.

Number of channels

Channels determine how many separate groups can operate in the same location at the same time without interfering with each other. This matters if you run tours at busy venues or alongside other operators.

• 16-channel systems allow up to 4 groups to operate simultaneously
• 18-channel systems offer slightly more flexibility
• 42-channel systems are designed for complex multi-group environments

For most operators, a 16-channel system is perfectly sufficient. If you regularly work alongside other tour groups at the same site, opt for a system with more channels.

Hire or buy?

If you run tours regularly — weekly or more — buying a system will almost always be more cost-effective within 6–12 months. If you only need a system for a one-off event or occasional use, hiring is a smarter option that avoids the upfront investment and storage considerations.

We offer both. Read our full guide to hire vs buy if you're weighing up the options.
