Remember this one from the eighties. When used with modulated audio, it was supposed to amplify the soft whispers which usually amounted to the deeper targets.

Besides The Compass Depth Doubler, There Was Also The Depth Master:smoke:

A lot of people got lulled into thinking it increased depth that their machine could get . Eg.: "doubled your depth", blah blah That is slick marketing, if not outright deceptive. THE ONLY THING IT DID was amplify audio. Of what your machine was ALREADY getting/doing. So .... if you had a wimpy cheapie set of headphones with low volume, by all means get it. Or if you had a hearing problem, by all means get it.
But a person could accomplish the same thing by simply getting a superior quality set of headphones. The device did not change the depth your machine got. It was only a volume amplifier. Sorry for the rant.

Prior to purchasing that set of Depth Master Superphones I was using the speaker on the detector with no phones. Being new to the hobby (1987) I might have took that bait about increased depth but overall they were well built and fit my head comfortably. I will tell you that at times I used them with no battery and they worked just as well for me with my younger pairs of ears back then

I believe the Bluebird was for the early Whites models. Also Plus models having volume control. Some required batteries and some didnt. Battery ones did better. Some of them did work....especially on analog metal detectors that lacked a volume controlTexadillo said:Yes John I remember those...they also had a model called the "Bluebird" for certain detector models. My first set of headphones were Depth-master Superphones that served me well back in the day
