Gidday to all.
This just in from Fish-On-Marine
Humminbird units will work perfectly in Australia. They will just display imperial units, no metric. There is also no background map but mapping like Navionics will work fine. There may be a small message on the bottom of the gps screen that this unit is not designed for use outside of the US.This is what the Humminbird calls geo-fencing. They do it to protect their overseas dealers.
Because of this, our company has decided to suspend shipments of Humminbird and Lowrance products overseas. For our overseas customers we highly recommend Garmin, Raymarine, Furuno, and Standard Horizon products. They offer metric units and there is no geo fencing in their products. Plus they are of the highest quality available on the market today.
