Some two-way radios get into more trouble than others. Employees drop them onto concrete warehouse floors, into mud at job sites, and in the snow during a ski trip! When durable radios are a concern, look for two-way radios in the "brick" format that don't feature a digital display. Brick format is usually the best choice when you know the radios will be treated roughly. Please note that brick format radios may still be used with similar radios that use a display. Often, construction workers and forklift drivers, for instance, might get a brick format radio, while the supervisor might use a digital display for channel-changing convenience. The brick format also makes the radio simpler to use, as there are no displays or additional information.
