Answers:
1. The Gold Edition (w/U-Boat Expansion Pack) is the latest version (i.e., 1.5).
2. If you click on the base of your Depth Meter, you'll see it change to deeper settings, the red line being the test depth. They can go deeper but each sub has it's limits. There was a thread here somewhere that listed the max depth of each sub type but I don't recall where it is.
3. The range of your current type of radar can be found in the Weapons and Sensors station (Click on the bottom clipboard tab followed by the gears tab on top). Then just click on the radar and it's specs will appear in the box. As far as the radar coming off sweep every time you visit the station, well, that's such a minor inconvenience as to be null on the annoyance meter.
4. You have a position keeper and relative
bearing meter at the periscope station. Have you taken time to explore your new boat?
5. I rarely get detected during my approach and after my attack. I never played SH1 but I'm willing to bet the realism in SHIV is more refined. You have to develope new tactics and that won't happen overnight. SHIV is not so much a game as it is a simulator.
6. The IJN became more aware of Fleetboat depths after the May Incident of June 1943. I believe all the major mods address this with accuracy, maybe even the stock version too but I'm not absolutely certain.
Tip: Take some time to explore your sub in earnest. SHIV is a sub simulation, not a shooting game. Each successive game is (should be) an improvement upon it's predecessor. This sim takes time and alot of patience. Hope this all helps some. Good luck.
