The VX3 gets better depth than the DFX.I had the spectra v3 when it first came out to be honest it was a little much for me in the way of using the menus,my question is do you guys think the VX3 and the DFX will get the same depth,of course in the same soil conditions .The price is so close to each other one just has to wonder .I have been THing for over 25 years now mainly using Whites and garrett metal detector and on the market for a new detector.How do you guys think the VX3 will fare on a salt water beach I know it has a beach program ....Thanks for the help Guys.....
