    Staying in touch with your teammates in harsh outdoor environments is crucial. If you spot an emergency, you can notify your team promptly; if you get injured, you can call for help; if you fall behind, you can ask your teammates to wait for you. In short, during outdoor expeditions, we need to stay in constant contact with our teammates to understand each other’s situations. However, mobile phone signals are unstable in the outdoors, and maintaining continuous communication isn’t always practical. So, what device should we use to stay connected with our team?
 

 

    The Rino 650 (Big Rhino) is the latest handheld GPS device launched by Garmin in 2013. Unlike regular handheld GPS units, this model features advanced two-way radio functionality, allowing you to stay in touch with your companions anytime, anywhere. When a team is engaged in activities such as hiking or exploring in the wilderness, the Rino 650’s (Big Rhino) two-way radio feature helps keep track of every team member’s status.

 

 


Quad-helix GPS receiving antenna and high-sensitivity two-way radio receiving antenna

 


Call button and talk button

 

    The Rino 650 (Big Rhino) can store up to 50 contacts. By setting each person to the same channel and code, you can communicate with other contacts, either reporting your own situation or listening to others. To talk, simply hold down the talk button (PTT), and release it when you’re finished speaking.

 


Microphone for two-way communication

 

    The Rino 650 (Big Rhino) supports a maximum two-way radio power output of 5W, with a maximum communication range of up to 32 kilometers. If a teammate goes missing, you can use the two-way radio function to contact them. Even if the missing person is beyond the maximum transmission range of the radio, their exact location can still be viewed on the map, and you can navigate to their position using the map. Of course, if every team member is equipped with a Rino 650 (Big Rhino), the risk of anyone getting lost can be entirely avoided.

 

 

    During outdoor activities, we often need both hands to climb trees, rocks, or other surfaces, making it impossible to hold the Rino 650 (Big Rhino) at all times. You can hang it on your backpack, freeing up your hands for other tasks. Don’t worry about losing communication with your team— the Rino 650 (Big Rhino) supports headset and microphone communication, which not only makes it convenient to stay in touch but also keeps your hands completely free, offering a very user-friendly design.

 


Rechargeable lithium battery pack with up to 14 hours of standby time

 

   In addition to its advanced two-way radio features, the Rino 650 (Big Rhino) can display current altitude via a barometric altimeter, show precise direction with a three-axis electronic compass, and present geographic location through its built-in navigation maps. Moreover, the Rino 650 (Big Rhino) supports multiple coordinate systems and display formats, including Beijing 54, Xi'an 80, and CGCS2000. It also supports track measurement, route measurement, and equal-width measurement, making it useful for surveying and data collection in agriculture, forestry, water conservancy, geology, and related fields.
