Hi,
i have recently downloaded this mission from subguru's website. So far i really enjoyed playing this "new" mission. Especially the new sound files are very cool and bring a lot more athmosphere to Sub Command. Unfortunately i have been faced with an unsolveable problem:

One of the Mission's objectives is to photograph a north corean sub base with either periscope and the "high frequency mine hunting sonar". The last thing should happen in a deep of 90 feet. How should i do this? The only high frequency sonar, i know, is the HF Sonar, which i can switch on in the controll room (688i Interface). But how can i "photograph" the base with it? The only thing- i remember, is to mark contacts,so that they will be appear on the Navscreen.
