There were 3 models
V3, V3i and Vx3.
I had V3i.
Oem battery run time lacking.
Aftermarket li pro was available some time back. Don’t know if one is available anymore or not. Units can be run with AA batteries,
Menu system complicated.
On the heavier side weight wise.
Nice looking screen.
Like pinpoint trigger and location.
Can be difficult to set up per site for maximum performance.
Has a lot of very minute settings for adjustments. For speed,,etc.
Machines will hunt.
New user will expect to put quite a bit of time in to learn.
I don’t recommend for beginner detectorist.
And believe it or not V3i was my first detector.
But I was retired and could spend loads of time fiddling with.
Think there were some counterfeits made too. Be careful.
V3 was more noisy why White’s made V3i.
Vx3 is a dumb down version of V3i and was cheaper.
Support for units I am unsure about,
Good luck
