Out yesterday from Carlingford; the fishing was pretty poor with one mark producing lots of small codling and coalfish, only 1 mackerel the whole day. This left plenty of time to play with the fishfinder. First picture shows the track from crossing a large lorry ferry wake with disturbance reaching to the bottom; I wonder if this disturbs the fish?
Next picture shows the water column and seabed devoid of fish. Third image shows small codling(up to 1lb) tight to the bottom. Fourth image shows a set of feathers jigged on the bottom. The recording shows one "wave" above another, the top is the swivel and the stronger lower trace is the lead. Conditions were a flat calm sea with little background "noise".
