Got my Sea Hunter yesterday and assembled it. The lower shaft is attached using only one nylon bolt and as such wobbles. Why would Garrett not put another hole for a second bolt to attach the heavy coil / shaft to the connector shaft. I heard about some shaft locks. Where can I get them and what are they called.? The shaft really wobbles as well as the arm rest. My other detector an MXT is rock solid using shaft locks on the lower rod. I took it out for a quick test run and found 3 coins and 2 bottle caps in the wet sand. I ordered a pro stock scoop 9 1/2" wide one today so I can go into the water. It does indeed go deep. Any info to firm up the wobble would be appreciated. Thanks. Marty
