Here is a photo of the After market Anderson balance shaft for the Infinium and Sea Hunter. They also manufacture a long shaft for the Infinium that places the electronics way back and also a short scuba shaft too. I know these have been around for awhile, but any Infinium accessories are welcome. I wish Garrett would produce an elliptical 10 inch DD waterproof coil for the Infinium. That would be easier to work with in shallow water, plus provide the benefits of DD coverage. CC.
