I designed this simple compass mount for my Genesis DPV. It attaches using a tank strap or bungee and allows magnetic correction for the installed compass. I tested it with the DPV and observed no magnetic interference from the scooter. The STL file is available to download from the Designs listing. Confirm compass accuracy and attachment security with your own equipment before use.
