unless you hunt by using visual ID first instead of sound...which you probably shouldn't be doing anyway.
The key to learning the Explorers....any of them...is 100% sound and sound alone.
The screen should only be used as a visual aid in helping you decide whether or not to dig only after you have gotten a certain tone that sounds good to you depending on what you are searching for..
The sweet "explorer high warble" on silver coins is unmatched by any other machine.
Even my E-trac doesn't get that same "high warble"...and although it's a super machine...I prefer the Explorers because of their unique sound.
If the processor isn't fast enough for you...you can always run with the fast setting "on".
I don't even do that though...even when hunting in heavy trash.
I just put on a small coil and slow down to a crawl...with fast "off".
The reason I do that is because I feel with it on...the sweet signal I listen for gets "chopped" short.
Just my personal preference...but trust me...there's nothing "slow" about the audio ID on the explorers. It is lightning quick to me.
So much so that when I tried my first explorer 10 years or so ago...I heard so many sounds so fast...I wanted to wrap it around a tree
