Landlubber saying "ahoy!"

[Bellman]

Kurushio as MaHuJa said some excellent players have never learnt/mastered manual TMA.

Coming fresh to DW I would address manual sonar first taking the Kilo which simplifies the process as
the absence of a TA removes the complication of sorting-out ghost contacts. Learn all the stations and practice
with Quick Missions. Move on to the 688 (some say Akula next) to get used to the waterfall then on to
the Ak where now familiar with the circular sonar and 'ghosts' you can now make better progress.
Finaly take the SW where the WAA is a benefit but the fiddly inter- phase takes some getting used to.

The QMs are a superb way of practicing and I would stay there initialy - its like a golf driving range -
get into your swing before you cut out on to the course.
