White's Surfmaster PI vs Surf PI Pro

[Rollin_sb]

What are the difference between the Surfmaster and the Surf Pi Pro? Are there differences in sensitivity or depth? Any idea of what years they were produced? Which is the better beach detector?

Thanks

I'm preparing to build either the White's Surfmaster PI or the Surf PI Pro. Which is the better beach detector? Your thoughts? Thanks.
