I have had my 5900 Di Pro for I think 5-6 years now...It is STILL the only land detector I have and use regularly....I have grown so used to its adjustments and quality of operation,I could just keep it forever,and use it as my ONLY land detector,FOREVER....I believe its that good-How about you other guys that own this model??There is a co-worker of mine that is getting into the hobby...He said something about he wanted one like mine-I told him"NO-Dont buy one like mine"--I told him for beginning,buy a easier to use discriminator-I told him if he bought one like mine-I dont think they even make it anymore-He would be completely and immeadiately overwhelmed with all the manual controls-Stick with something Turn-On-And-Go easy.He then asked me"What does turn on and go mean"??Keep it simple,indeed....
