Gayle,
I purchased a straight shaft for my Excalibur II, but found that I couldn't pack the Excalibur with the long straight shaft into my car or motorhome.
I then tried the swingything harness using the standard shaft, and what a big difference that makes.
The swingythingy takes the weight off your arms, and spreads it over your shoulders, chest, and pants ( the swingythingy clips above your back pants pocket).
It makes the excalibur almost weightless, and it allows you to work hands free when digging up treasures.
I use the swingything with both my detectors now, and I can detect for much longer without getting tired.
