Know where you’re going, where you have been and keep in touch. Comms are important to keep safe and connected on the trail.
High quality, offroad-specific navigation is a high priority item as it’ll keep you on the right trails, aware of the weather, and safe if an emergency arises.
CB/Ham radios let you keep in touch with your group and potential support. Most group rides like Jeep Jamboree require CB radios so you can communicate with spotters and the larger group.
If going out solo, or in a smaller group, it’s critical to have GPS-based communications. If you get stuck or have an emergency, it may be your lifeline back to civilization.
