Hi: Considering that a large percentage of the followers of this chat page are divers searching for shipwrecks I'd like to let everyone know that I've placed a Geometrics G-846 magnetometer up for bid on eBay (#1116298596) with a bid price of $800 US. The unit is 1-gamma and would provide an excellent means of 'proofing' a sidescan hit. The same model was used to truth the side-scan target that turned out to be the 'Brother Jonathan' in 260' of water here in Northern California and yielded 1300+ gold coins. Thanks
