I've been using this add on that comes with your mod TDW and have been getting no sound contacts at periscope depth (say 10/15m).I had to go down below 20m for the hydrophone guy to start reporting contacts.
I switched to your UI version included with your UI mod package and reports come in as soon as I'm at periscope depth. Thought I'd report it to you.
The in game action with IRAI is great. Whilst starting out on patrol from France I encountered a German freighter and sailed along side for a while.
Three Beaufort torpedo planes were spotted and came in to attack the freighter. A very intense battle ensued with my boat shooting down 2 of the planes and the freighter getting the 3rd. My boat sustained slight damage and unfortunately the freighter took a torpedo.This type of game play is exactly what I've been looking for in SH5
