I have been using my stick detector made from a this https://newhobby.eu/en/home/172-54-p...ound_coil_6_cm a Teemo design. Works well especially with the LED lights blue for ferris and red for non ferris when detection is found, so simple with out a LED display just basic. Very discreet with folding head with the coil shaped into a oblong to make more compact. I have found quite a lot of things with this design, Its only problem is depth, it could do with about have two more inches of depth added or more for it to be perfect. A friend of mine suggested replacing the 6cm search coil with a 4.5 inch sniper coil, could this be done or would i have to change anything on the circuit board and battery voltage etc. The 4.5 inch coil could be incorporated into the walking stick design as a walking stick seat though it wont be used as a seat.

"Very discreet ... with the coil shaped into a oblong to make more compact"
This will make the coil perform more like a coil the same size as the width of your oblong. If you are going to try experimenting with larger coils, I suggest making the width 6cm or 7cm ( and the length presumably 9 or 10cm ). I don't think 'large' coils will work well on this design - you may get undesired responses from electrical interference, or the Earths magnetic field, for example. -
Looks like the circuit design is not going to be suitable to upgrade to go deeper with small sniper coil to keep it discrete to the stick project. I most probably need a circuit design or kit or made up board, that i can use such a coil but also have the discriminator feature showing the led lights picking up the ferris and non ferris finds. I find this feature plain and simple than showing a led screen. Any such circuit discriminating boards about?
Would this design work better with a sniper coil and is Teemo still currently selling these kits, anyone bought one.Comment

He did reply to a email i sent him if i could fit such a coil here is his reply,"you cannot use a standard coil from MD - the coil for pinpointer must have inductance 1500 uH. It is used for generating frequency, not for emitting signals.
I tested this model with a large coil (not remember - 15-20 cm) - the distance increases very little. That's why I sell it only as a pinpointer"
Great pinpointer, though i could get a little bit more depth but not to worry, if i could find a similar sized board with the light features with a bit more depth using a small coil like a sniper coil, that would be great.

I made a 10cm coil a while ago just for testing and it worked perfectly only the wire should be firm if it moves it gives a false signal
