The AI_Sensors.dat file does indeed get alot of modification from several authors. I have several version depending upon what a person wants. Stock game, Ortega Visibility Mod, or RUB are the big three.
The Snorkel fix is very simple way to deal with the large size of the snorkel being seen. It simply is an one value hex edit to the MinHeight of the AI enemy Visual from zero to 1 meter.
It is one of them things you can add to any mod. I placed in the newer versions of SonarDC. You may notice not as many people having problems with the snorkel attracting planes like a dog to the bone. I placed the new info on the fix in the readmes', but not everyone reads them or remembers.
It tends to be a group effort. Even SonarDC in the original took alot of people testing and helping to get it off the ground. I realize that and realy I should include all those that helped design it such as Berry and CCIP and others. So I guess it was not really all mine to dictate.
(Or mine to give away to X1 when others put work into also. I know stupid me for being fooled thinking I was helping to make an official UbiSoft expansion for SH3 to give the game more exposure and leads to more chance of a sequal -it was an honest gesture

).
Anyway, some people have different styles of play and never have a problem with the snorkel. This is a small change that has no side effects at all I ever found (other than fixing the snorkel from being spotted from an airplane 8 km away).
It is a simple change to MinHeight for AI_Sensors.dat from zero to 1 meter. I think everyone should be credited for helping to create the combined efforts that has gone into that particular version of AI_Sensors.dat. Many mods affect it and need to be integrated.
I can understand what a book keeping nightmare it can become. I am running into it making so many custom mods and tweaks for this and that other persons mod or package.
So what does it mean? If you like the snorkel fix, include it. It does not bother. The more the happier, I am flattered

. I hope it makes the game more playable. The credits are already there for all who works on it and putting it all together into a funtional package.
I have made custom version of AI_Sensors.dat for some people that includes Snorkel fix, similar to the 'clear water' changes to customized versions of RuB.
It maybe 'one' reason no one is complaining about the snorkel attracting airplanes like honey anymore. Hard to say. many use the custom version of AI_Sensors.dat, many do not.
