detector stem

[satdaveuk]

hello,

i has already replaced the lower parts of the elbow crutch with a 25mm cable channel pipe.
Over the cable channel you can place another one cutted in length and over them you place a shrink tube. So you can get a very stiff lightweight and good looking lower part.

But i´m wondering that the professional stems often have a lower metal part.
It can take effect on the magnetic field thats clear but it´s not moved in relation to coil - so it is equal or not?

Interesting one Bernte, I would say its equal but theres some say its proberly not.
All the early mainstream upmarket detectors i came accross had metal shafts, maybe its worth trying with and without, Now you have created another survey for us all to do.
All the best mate
Dave

These work quite well for the upper.

Simply replace the lower stem with PVC.

You can heat the end of the PVC and clamp it to get it to fit within the Coil Ears.

hello,

i´m still looking for the perfect selfmade detector stem.

If anyone has an idea post it here.

I uses most time an elbow crutch.

there are some newer models which you can fold

Another good idea ive used in the past is using exstention telescopic assemblys used for paint rollers, you need to substitute lwr stem with water wast pipe or such like for ovious reasons, but they do a cheap light job and look the business.
Another one is using exstention telescopic rod thats used for car cleaning brushes.
And another option is, if you want to go real cheap and dont care to much on cosmetic, use one of those exstention rods that are used in the middle of wall to wall washing lines, there cheap and chearfull about £2-50 in uk.
All the best

Nice upper parts, but lower part have to be nonmetalic.

I am using mostly cheap bamboo for my testing devices.

For my "hiking" detector I am planning to adapt Portable Telescopic Carbon Fishing Rod for this purposses:
