Raymarine depth ST40
End of season clearance. This is new old stock, 3 mth guarantee. Can UPS for a tenner.
ST40 depth (display only) £100 + vat + delivery = £130 delivered next day
I also have an Airmar P66 transom mount transducer to suit which is worth £100 on its own.
Both for £150 + vat + delivery = £190 delivered next day
I cant see anyone wanting one on a RIB, but I do also have a P7 "thru hull" transducer which I would do at the same price.
