ok cos. nobody seems to have an answer yet
lowrance HDS series ARE geofenced
the sounder will work. but in US imperial only
the GPS will NOT work. even with local navionics maps
lowrance elite and mark series arnt geofenced
now why i said that as a lowrance retailer. who knows... however when a US unit has issues "and they will..cos... they are lowrance
" aus retailers arnt... ment... to aid in fixing. and navico australia def wont help. so that international warranty is true.... you just have to send it international post back to the US for repairs.
