Well I've done an awful lot of research (translation: Youtube reviews) on metal detectors and I ordered a Minelabs Vanquish 540.
Seems about dollar for dollar the best metal detector going.
Guess I've gone and stumbled onto a new hobby... and I'm damn sure i'm going to recover that dang crossbow bolt too!

It's time to go hunting and quit all this ballistic masturbation."
