I'll run my V as high on sensitivity as I can for the spot..The reason is simple, the town was formed in 1805.While most of the stuff is up top, every once in a while you will get a great deep hit.. The ones not to be missed...I. also, am practicing with the 3 by 18 coil for open field sweeping. There is no set hard fast rule how to set any control or how to play the scene, other than the one stated by Pop Eye..."Yas does whats yas gotta does,Olive"..I went out for a bit playing with the V and the wide sweep coil..The song,"Like a Rock", described the ground....It was cold !! How cold? The local witches were all wearing 5 and 6 sweaters...I quit when my feet started hurting, this was after the fingers cried "Uncle!!!" Below 20 easily,with wind... The V cooking along ,sounding off when we got to a signal..(These were neighbors back yards) The second yard over is going to be a problem.Old Elsey was a black smith, may be iron.But, there still may be the other half of the cast iron elephant pull toy left..Would really like to find it and re-assemble....Keep warm, and send some warmth North,if you have extra...... cordially NAD.
