Hmmm...thats no good.!.
A fellow would think the majority of the 'target market demographic' for a detector mfg. are 'guys over 50'...Being in that classification myself, most of us are nearly deaf, so it would stand to reason a mfg would make sure the volume strength coming out of the brain box is full power and as loud and crisp as possible, even to the point of pain for younger ears...the younger single guys could always dial it down and balance it at the phones? I do this with my 70, I run it full power from the On/Off knob, and balance the signal accordingly at the phones..If I accidentally put my phones on backwards, or the phone knobs get out of whack, I cant walk a straight line!

.
Any old guy needs a hard crisp clear balanced high volume command to stop a fellow dead in his tracks!...All of us who are long time married know this!...All the tiny little muttered and mumbled annoying signals are habitually ignored as back scatter chatter by old married guys,
example: "I saw Jenny at the Piggley Wiggley today, She said Bruce has a colonoscopy scheduled Thursday and she has to do the laundry" "The Hummingbird feeder needs filled, the gutters need to be cleaned",
"Does this smock make me look fat?"etc.
A rig or Wife has to YELL to get our attention! "Silver Dollar!"
Now I wonder if theres Factory specked max 'Decibel ratings' on rigs, if so, whats the 19 got? What do all F rigs have? All of them should be well over 100db...like a top fuel dragster, or a Wife who sees a spider! Right? Pavlovs dog kind of thing going on here....We really are that audibly tone deaf and simple...
