A friend is considering getting into our hobby after going hunting with me a few times with my cz3d. He asked me for suggestions on what machine I would suggest he purchase that is equivilant to the 3d. Ease of learning was his biggest concern and since I have never used any other machine I could not compare machines. My question is,is the 3d considered an easy machine to learn compared to other Fishers,Whites,Minelabs,etc.? What makes one more difficult to use versus another? Thanks!
