From the end of 2020 all Easy Swings sent will be the new MK111 version with minor modifications to the end elastic fittings.

This is our most popular product by far. 
The Easy Swing Bungee Harness was  designed to help stop repetetive injuries and sprains whilst using  a Metal Detector. 
After having problems myself whilst swinging in long corn stubbleI needed  to try and help stop things  like tennis elbow developing through continuously  using  a detector for several hours in such situations.   The Easy Swing is the result and I have used one ever since even on the lightest of detectors like the XP Deus. Its not the weight so much causes the problem but the swinging.

Here is a short video made by England History showing how to wear Easy Swing
