Fishfinder or depth sounder
i just bought a Raymarine ST60 tridata for my c-30. the current depth gauge is dead. i few weeks back there was a thread about depth gauges and one or two people mentioned getting a fishfinder instead. i was also planning on buying a handheld gps sometime this summer. looking in the sailnet store, there are color fishfinders w/gps for little more than the st-60 tridata. which would i be better off with. i'll be mostly sailing narragansett bay, block island and up to martha's vineyard. also, any fishfinder/gps that anyone could recommend.
