If you're not satisfied with the Bluetooth detector on your PC then try BluetoothView which simplifies connecting to Bluetooth devices.

BluetoothView is a small utility that runs in the background and monitors the activity of Bluetooth devices around you. For each detected Bluetooth device, it displays the Device Name, Bluetooth Address, Major Device Type, Minor Device Type, First Detection Time, Last Detection Time and other minor details. The program works very discreetly and only notifies you in the taskbar with a popup when it has discovered a new device. However, if you don't want the balloon in your taskbar, you can always instruct it to use a beep sound instead. To be honest, unless your bluetooth detector on your PC is really poor you don't really need this utility but then again, if you constantly work between Bluetooth devices, then you'll find it a much better way to find and connect than manually searching for them.

If you're a heavy Bluetooth user, then you'll find that BluetoothView makes life easier in finding the devices you need to connect to.
