Best sonar ping mod

[RConch]

I play GWX 3.0 and I was wondering if there was a better ping for the sonar than the stock game supplies.
What do you guys use?
Please provide a link and if any problems with the mod.
Thanks:salute:

I made a mod based off of an actual recording of a ping hitting a submarine in the 1940s or 1950s. Link in my signature.
