The new Casino Heist update brings a lot of new content and a brand new heist approach strategy which is similar to that of story mode heists. However, the fun doesn't just end there, there's a lot more you can do to enhance your Casino Heist experience, including unlocking new casino heist members through a collectible side mission.

CASINO HEIST HIGHLIGHT VIDEOS

Yes, that's right! You can unlock more heist crew members, one of which is a hacker named Avi Schwartzman. He is an expert level hacker and will therefore take 10% of the final cut of the heist. Having a better hacker during the casino heist means you get to have a longer period of time until you need to leave the vault... which means more loot / a higher payout!

You can unlock Avi Schwartzman by collecting 50 signal jammers which are spread through out Los Santos. Just note that the word "collection" in this sense basically means destroying! You need to destroy all the jammers at which point Avi will be unlocked and available as one of the crew members under "hacker selection" on the heist prep board in your arcade basement.

Avi Schwartzman

Fun Fact: You also come across Avi during the Pacific Standard Job - Signal set up mission in GTA Online. He is the hacker you rescue from government agents and that helps you tune into the Pacific Standard Bank frequency.

When you are near a signal jammer, you will hear a static sound effect which will indicate the presence of the signal jammer.

This guide will help you find all the signal jammers in order to successfully unlock Avi as a crew member of the casino heist. If you prefer a video guide then you can also check out our video on all the locations on our Youtube channel.

Frequently Asked Questions

Do you need to have the Arcade in order to find the 50 Signal Jammers?

No, you don’t need an Arcade to find all the Signal Jammers. However, after you unlock Avi, you can only choose him as a hacker for the Casino Heist. Therefore, you need an Arcade to choose him as a hacker for the heists. But unlocking him by destroying the Signal Jammers doesn’t require you to have the arcade.
