HT Marine LCD - UHF

Overview Features Accessories Technical Specification

Superseding the multi award winning HT series 1.0 was a challenging task considering its success with the fire & rescue services, major blue-chip petrochem organisations, as well as shipping companies worldwide. The HT Series 2.0 marine portables build upon this success.

Utilising the latest intelligent Lithium-Ion battery technology, these marine portables give you the option of displaying a battery cycle count each and every time you power-on your radio.  For your convenience it will even alert you to imminent battery life expiration.

The commercial grade HT Series 2.0 portables, with their exceptionally loud audio, are also designed to withstand the every day rigours of life at sea, with superior MIL-STD 810/C/D/E/F construction and IP68 submersibility making them the most robust and durable marine portables on the market.
