The T704 Micronet Race Master System is part of the wireless range by Raymarine. Offering versatility, simplicity and reliability, the Raymarine wireless instruments are easy to install without drilling large holes in your bulkhead or wires to thread down your mast. Lightweight, portable and solar powered with integrated lithium batteries that power the unit for life and can run autonomously for up to 300 hours. Included in this system pack is the T070 Race Master which contains a two-tier display that shows your heading, how far you're above or below the mean course, and how much you're being headed or lifted. Enabling you to quickly establish the favoured end of the start line with ease and also allows to sail the shortest distance to the windward mark. This truly is the ultimate race compass and wind shift indicator.
