I made this after being mildly frustrated with tracking down cap stashes with the Fortune Finder perk. I disliked how the sound only plays every couple of seconds, having to frequently stop and keep an ear out, walking in a direction for a bit only to hear it in a different direction when it goes off again. With this mod, it's much easier to follow the sound.

Here's a short video preview of the mod in action:


The video only shows off the caps stash version (since that's the only collectible finder perk I have/want), but the sounds for bobbleheads and magazines are similar, just with bobblehead and magazine sounds instead of caps.

To install, first create a "Fallout76Custom.ini" in the following directory (if you don't already have one):
C:\Users\Username\Documents\My Games\Fallout 76\

Then, put the following lines in the Fallout76Custom.ini:
[Archive]
sResourceArchive2List = BetterCollectibleFinderSounds.ba2,

or, if you have multiple mods:
[Archive]
sResourceArchive2List = ExampleMod1.ba2, ExampleMod2.ba2, BetterCollectibleFinderSounds.ba2,

then, simply place "BetterCollectibleFinderSounds.ba2" in your Fallout 76 data directory, which by default is:
C:\BethesdaDotNet\Bethesda.net Launcher\games\Fallout76\Data\

or, if you have the game on Steam:
C:\Steam\steamapps\common\Fallout76\Data\

Enjoy!
