Well thanks for all your help with my "coil best suited for prospecting" question but i am still not sure. Talked to someone at kellyco and he thought maybe the 5" excelerator coil as it is a DD. Garrett tech. was not sure about the excelerator but thought the 5x10 scorcher would be well suited for the highly minerilized ground. Has anyone tried the 5" excelerator or heard of anyone who has used in any situation. Thanks for all your help. Rob
