I recommend you BaoFeng UV-5R Dual Band Two-Way Radio.
The dual-band two-way radio from the brand BaoFeng includes a strong antenna that is 7-inch high and can be easily bent over. Its channel step ranges from 2.5 to 25Khz. This radio is engineered with a battery saver mode and a low battery alert so you can be aware when it is running out of power.
I enjoy its commercial durability, which makes the radio much more compact to be used as a BaoFeng UV 5R airsoft setup equipment. The frequency range it can receive in Mhz is VHF (136-174) and UHF (400-520). It contains a large push-to-talk key along with two other side keys for alarm, flashlight and monitor.
What is more impressive about this UV-5R radio is its sturdy body made out of high-quality dense polycarbonate. This feature helps to enable its overall durability in such a competitive team sport like airsoft. It is capable of resisting pressure; thus, it would not become a big deal in case you drop it during the game.
You are free to have tri-color background light choices from a built-in VOX feature of 0-9 grades. Its output power can be up to 5W with a high level of safety. Should you plan to use the voice companding function on this radio, it has a 50 CTCSS and 104 DCS coder, which includes 128 different channels.
