The meter is very helpful for at least two reasons that I can think of:
1. It helps you identify trash and treasure that you see over and over, like pull tabs, bottle caps, and coins, especially on the beach. The numbers don't lie, but unless you have perfect pitch I don't think anyone can remember the exact pitch of a target. I have an aluminum bottle cap that pops up over and over between 176 and 179, and I can't tell it apart from a coin that comes in at 180. The tones are way too close together for my ears, but I can spot the difference easily on my meter.
2. Targets come in hundreds of different tones, and it's just easier to remember a tone number, than it is the actual pitch of the tone. You can also make a chart showing different targets and their numerical values on the meter. Some meters come with an ID chart as part of the package, showing gold, silver, coins, etc.
Other hunters can add more reasons to use a meter. But learning the timbre of a tone is also very critical to target ID, and it takes a lot of practice to become proficient. But once you learn it, there is no other detector target ID system, computer or not, that can beat the Sov, your ears and your brain.
Good Hunting and Good Luck
