With the pulse timing adjustment you will lose depth. It can be used to eliminate some reaction to iron and with heavy mineralization. If you are looking for large objects, just learn to listen to what your machine is telling you, you can generally tell the size of an object based on the size of it's reactive field, and can easily skip anything that is small. Remember though, the machine will only go so far down, so if you are looking for something at 3 feet down that is large such as a pipe, you will probably need a double box machine.
