There are multiple treasure hunts that are available in GTA Online. They all have varied rewards and reasons why you should do them. However, hunting for signal jammers might be one of the most difficult hunts yet, but it is also the most rewarding.
This is especially true for players that want to take on the Diamond Casino Heist in GTA Online. So if you want to give yourself the biggest payout possible for the Diamond Casino Heist, we have a guide to help you do so here.
Where Are The Signal Jammer Locations In GTA Online?
Out of all the collectible missions in GTA Online, the signal jammer hunt is one of the most difficult ones to do. One of the reasons for this is that the signal jammers are not often on street level. Players will have to look up to find the signal jammers. The signal jammers are almost always in a high location.
The jammers could be on billboards, on tall buildings, and on other high locations. The jammers also have to be destroyed to progress with this scavenger hunt.
To make this easier, we suggest you use The Oppressor MK2 to find the signal jammers and use it to destroy them. The Oppressor can both fly and shoot weapons out of it, making it the perfect vehicle for this hunt. As for the actual locations, the picture above has the exact locations where you need to go to find the signal jammers.

What Is The Reward For Finding All The Signal Jammers?
The base reward for such a difficult mission is pretty small. The immediate payout is that you will get around $150,000 and around 50,000 RP. That in itself does not really make the signal jammer mission worth it.
The actual real reward that makes all the effort you go through worth it is Avi Schwartzman. He is a hacker that you can recruit to help you with the Diamond Casino Heist who is better than the rest of the other hackers. For just 10% of the cut, he will give you a full 3 minutes and 30 seconds in the vault. That is an extra 15 seconds in the vault which is absolutely essential if you want to clean out the vault.
