Entel HT644 VHF Marine Two Way Radio

Product description

The Entel HT644 has been designed to meet the challenges of life at sea, and comes pre-programmed to 58 marine channels, 10 weather channels with 36 programmable private channels. The 58 marine channels can be switched to comply with USA, International and Canadian channels.

Manufactured to the highest standards, this robust radio has IP68 rating, which means that is completely submersible to 5m for up to 1 hour, and exceeds MIL-STD 810C/D/E/F standards for resistance to shock, vibration, dust and moisture. Advanced noise reduction technology ensures excellent audio quality, and with VOX, it can be used hands free with an ear piece, which can be connected to the radio via its especially designed robust accessory socket. This waterproof socket can withstand any amount of rough use and features a securing bolt to protect the connector.

This radio comes with advanced Li-Ion battery technology. The intelligent batteries count the number of completed charges, alert users to the imminent end of battery life, and the elimination of the memory effect means that you don't have to worry about running the batteries completely dry before recharging.

The large LCD display shows information such as channel names, battery charge count, signal strength, etc., while a 7-button keypad provides direct access to functions such as channel scan, weather channels, etc and can be used easily with or without gloves.
