With my eye on it's automatic zone-larm I am planning on installing a
Furuno 1623.
Some time ago I have read somewhere that users drilled a hole in the
fot of the dome in order to let condensed water pass. Anyone here with
experience regarding this allteration? Or with experience with
problems due to condensed water?

Fair winds,
Len.

My JRC and Raymarine radars both had drain holes in the bottom of the
raydome. Are you saying the Furuno base has no drain hole? I would think
its there somewhere.
