If you're looking to unlock the Hacker Avi Schwartzman for the Diamond Casino Heist and earn extra rewards in GTA Online, you'll need to destroy all 50 Signal Jammers hidden across Los Santos and Blaine County. These jammers were added as part of the Diamond Casino Heist update and can be found on rooftops, towers, billboards, and other high locations across the map.

This in-depth guide to GTA V Signal Jammer locations will help you track down every jammer quickly so you can complete the challenge and claim your rewards.

What Are Signal Jammers?

Signal Jammers are small electronic devices scattered around the map by the Duggan security network. Your objective is simple: find and destroy all 50 jammers. They emit a faint electronic buzzing sound and have blinking lights, making them easier to spot once you're close.

You can destroy them using:

• Guns (sniper rifles work great)

• Explosives

• Homing missiles from vehicles

• Aircraft weapons

Many players prefer using helicopters or flying bikes like the Oppressor Mk II, as the jammers are often placed high above ground.

Rewards for Destroying All Signal Jammers

Destroying all 50 signal jammers gives you several useful rewards:

• Unlock Avi Schwartzman as a hacker for the Diamond Casino Heist

• $150,000 total GTA$ reward

• Additional RP

Avi is one of the best hackers available, giving you more time inside the casino vault, which means you can grab more loot during the heist.

Where to Find the Signal Jammers

Signal jammers are spread across the entire GTA Online map, including:

• Downtown Los Santos skyscrapers

• Construction cranes

• Radio towers

• Billboards and highway signs

• Industrial areas and docks

• Blaine County mountains and facilities

Because many jammers are placed high above ground, flying vehicles make this challenge much easier.

Pro Tips for Finding Them Faster

• Use a helicopter or Oppressor Mk II to reach high locations easily

• Listen for the buzzing electronic sound when you're nearby

• Bring a sniper rifle to destroy distant jammers

• Follow a map route to avoid backtracking across the map

Once you destroy the final jammer, you'll receive a notification confirming that Avi Schwartzman has been unlocked.

Final Thoughts

Tracking down all 50 GTA V Signal Jammer locations might take some time, but the rewards make it well worth the effort. With a flying vehicle and a good route plan, you can complete the challenge in under an hour.
