Running multi freq is not good for nugget hunting however, if you can pick a specific freq turning others on and off to check before digging now that's something cool Alas the V3I. But like a carpenter or mechanic you should use the tool specifically designed for the job it usually will get the job done better. Not to say others wont do but its like using a SAE wrench on a Metric bolt you can get it to work but its gonna be sloppy and might make things harder in the end.
