Anyone who is good at their job knows that they need the right tools. The same is true for people who work as spies and keep watch. It's important to have the right spy stuff. You need to be able to get the job done and impress your clients with your high-tech looking spy gear and up-to-date skills. You have to spend money to get the right spy gear. If you do a good job with your spy gear, happy clients will send you more work and tell their friends about you. So, even if it costs money at first, if you have the right spy gear you can make all of that money back and more.
Listening devices are at the top of the list of must-have spy gear. You shouldn't only have one kind of tool. In different situations, you might need a different tool. There are many kinds of bugs, from cheap RF ones to more expensive cell phone ones. Also, it's a good idea to have a device that lets you listen from a distance by pointing a very sensitive microphone assembly at the target. This can't be found like a bug that stays in the same place. And people can talk to each other 300 yards away. It's also a good idea to have "wires" that you can wear, like a lapel pin listening device or a pen.
There are also good to have visual recorders. In this category of spy stuff are things like hidden cameras that can be worn and cameras that stay in one place and look at one spot. Also, don't use cameras. Instead, use cameras that look like other things. You can now use digital recorders that can send information through email, so your clients can see your work almost right away.
Last but not least, you need some kind of computer monitoring system to round out your spy gear. This lets you write down what you see or hear, and then you can use the information well. With the right programme, you can also use monitoring to keep track of your goal.
Even though this isn't everything you'll need to be a real spy, it's a good start. And it's this important gear that will help people notice you. With the right spy stuff, you're on your way to a good job.
