1. Shell:

Professional machines generally use PC+ABS, plastic materials with very good performance, good appearance gloss, not easy to age, wear, durable products; Commercial machines often choose engineering plastic ABS, which can meet the requirements in appearance, strength, wear resistance, aging and other aspects. The buttons are made of silica gel, resistant to wear and aging, and feel good. The aluminum shell is made of aluminum ADC12, which is light weight material.

2. Host:

Generally, it includes case, PTT key, earphone and power socket plug, PCB component, LCD part, volume/switch knob, coding knob, indicator light, MIC, etc. The PTT button ACTS as a transmitter switch, usually on the side. Indicator light indicates working status, usually at the top. The top of the interphone also has a volume/switch knob and a code knob (to select the channel). The LCD part displays the working status of the walkie-talkie. PCB assembly is the core part of VHF Marine Radio walkie-talkie, all the important parts are on PCB, non-professionals are not allowed to remove. Most walkie-talkies have special shielding cover, aluminum shell (fixed PCB), etc. Professional machine also waterproof requirements, more complex structure.
