I switched with a buddy once on a hunt and used one for awhile.
Good machine, but like most Minelabs here is the best tip I can give you with my limited experience...
Swing slow...this is not a super fast machine and you need to give it time to acquire targets and the correct swing speed is paramount.
I use faster units because I am a naturally fast swinger but even with those when I finally forced myself to slow down I started to find way more.
Learning good habits from the beginning is way easier than attempting to relearn them later.
