How to fish with a sinking line

Sinking fly lines are for getting down to lower levels of the water column where the fish are feeding. Fish feed at different levels depending on factors such as temperature, so it's vital to know how to tell where they are feeding so that you can select the correct type of fly and line.

There are different sinking densities from slow sinking which typically sink at around 2 inches per second, medium with a sink rate of approx 5 inches per second, to ultra fast sinking lines which sinks at up to 8 inches per second.

Alternatively you may wish to use a intermediate or floating line to obtain a different sink rate.
