Hi Bjorn,
Dave Emery 4/5/2006 - "Question: Does the Pulse Devil discriminate? The Pulse Devil sports a VLF type of discrimination control. You can adjust it from iron and nails through foil and pull tabs all the way to bottle cap reject if you wish. The audio tone varies for accept and reject targets. All non ferrous targets indicate as non ferrous and all ferrous targets indicate as ferrous".
Dave Emery March 2007 - The LCD display now displays the target ID in super large, easy-to-read numbers. The number is negative for ferrous and positive for non ferrous. The TID provides the same number for the same type of target just as the TID circuits found on many high end VLF detectors do. The TID is quite accurate. The TID will output a negative number for a ferrous target and a positive number for a nonferrous target. Low conductivity targets such as cupro nickel coins will provide a low number such as +50 while a high conductivity target such as a
silver coin will provide a higher number such as +180. The full range discrimination control is provided to allow the
detector to be used for coin and relic hunting in addition to its use in prospecting. The discrimination control settings start at iron rejection and goes to foil rejection and then all the way up to pulltab rejection".
Dave Emery February 2008 - The other detectors I will soon be selling include the original Pulse Devil. This is a tri-mode detector. The modes are coin and jewelry, Relic, and prospecting. I have delayed this model as my potential customers haveindicated that they prefer a dedicated gold detector over a multi mode
detector. This made a lot of sense to me so the Nemesis was born.
The Surf Devil is a waterproof version of the basic Nemesis except that it is
designed for beach hunting and diving to a depth of one hundred meters.
The Nemesis is the first detector scheduled for sale. There is also a virtually identical model which is designed for coin and relic hunting in
Europe. I will be demonstrating this version in France and England in the next month. After this I will be in Australia to do the same.
The first Surf Devil will be tested in Hawaii by a well known surf hunter".
Dave Emery February 2008 - "The US version has an additional discrimination control as it will be used for coin hunting. The control is full range and acts just like a VLF's discrimination control. There is also an extra switch to select a relic mode".
So there you go. Full range VLF style target id in a pulse induction detector. But hey, the Oz prospectors have priority so let's just shelve this thing. It does not make sense to me.
