GW2 Sonic Periscope Audio Log guide

GW2 Sonic Periscope locations guide for the Flame and Frost: The Razing Patch.

Sonic Periscope Audio Log

There are 50 Sonic Periscopes found across five areas: Diessa Plateau, Wayfayer Foothills, Snowden Drifts, Plains of Ashford and Iron Marshes. Each zone contain 10 Sonic Periscopes. Destroy these periscopes to loot the audio log. The periscopes reset daily and can be looted again the next day.


When you are near a sonic periscope, you will hear a loud noise and there is an aura around your character


Each Sonic Periscope Audio Log will yield 100 karma when handed to the collector. The collector has the collection icon on the map.

    I don’t understand how to translate them? Agent Badaboom doesn’t want the 12 logs I collected, and I can’t seem to use them on the continuum transfunctioner, or vice versa. I told him I lost it, and he gave me another one so now I have a stack of 2 of those. 🙁

    • Amadahy

      Well, now I realize this has nothing to do with Secret Contact. What then is the purpose of this?

      • Just karma I guess

        • the pigman

          Oh and um, I don’t know, a little thing called story immersion/plot development too, I suspect.

  • Dargon

    There is another sonic periscope that appears just SE of Kevach’s Homestead in Wayfarer Foothills, basically, due south of the lodge, and due east of the wurm cave

  • Biscuithammer

    So where do you take these logs to?

    • Audio log collectors, they are marked on your map

  • the_void

    I’ve been searching Wayfarer Foothills for a few hours and I still can’t find the 10th sonic periscope’s location…

  • the_void

    Is there an Audio Log Collector in Iron Marches?

    • Yes at Village of Scalecatch Waypoint/Monger’s Sink

  • The_Void

    I found the location of the 10th sonic periscope in Plains of Ashford:

    • added it, ty 🙂

  • Wicker

    Hey Dulfy does this have any achievements or just the karma points? Thanks

    • Just karma points

      • Not any more – it’s part of April’s monthly achievement. Turn in 150 logs to complete.

  • digi_owl

    Do wonder what braniac at ANet thought it would be fun to have a periscope sitting on a narrow hill right next to a vista….

    • Michael Clarke

      i TOTALLY agree with you on this point, mate! It is a royal pain in the
      arse to be subjected to this kind of sadistic nonsense from a game
      developer. Especially when one cannot even get within rifle-shot range
      to deal with this incredible nuisance.

  • TY for hints! I can complete monthly now without redoing 12 jumping puzzles or finding a super faster better computer to handle the lag in WvW! <3 <3 <3 So excited to waste my Laurels on Chauncey von Snuffles III! That's exactly what i'll be doing in a few days!! *confetti* *cartwheel* LOL

  • Cataclysm

    Note that these 50 locations can only be looted once a day per account. It’s not character based like other achievements/events.

  • Xaryn

    Thanks for the guide! These things are a real PIA! Oh, and I enjoy when the Vets and mobs that pop up afterwards 😛 Cannot believe they made this part of monthly achievement!

    This event sucks balls. Worst crap so far on Gw2 ugh.

  • Bubbagrim

    28 more to go in T3 then 50 more, be glad when this is in the bag.

    2 Nights in a row ive done Iron Marshes to farm for my monthly and came up 1 Audio short. I know for sure its ether #5 or # 8 sonic pariscopes that doesnt give you the audio. Ive back tracked through the intire map 3 times last night and then checked every other map, took 5 hours. But the same thing happened in this map I came up short again. I carefully kept track of the number of audios I was recovering and found that those Pariscopes arnt giving the loot.

  • BeBeBi

    For those who still need it , guardian with “hollowed ground” and “stand your ground” does wonders. no knockdowns 😀

  • undouble

    #1 in Snowden Drifts can be relocated to “adjacent to the Angvar’s Trove Waypoint (for greater clarity)

  • Bubbagrim

    41 more to go….
