Hi everyone, --- I recently acquired a Deus, and of course really love it. --- It has the 9" coil with version 4 software. ---- Would spending nearly $500 on the 11" coil be money well spent? --- I have watched the Youtube videos, and some say it is super, while others say you may gain only an inch.( I do like covering more ground, but separation and recovery speeds are important to me as well), probably more so than depth. ---- I mostly coin shoot, with a little relic hunting thrown in. --- Is there a market for a slightly used 9" coil if I decide to buy the 11"? --- Is there a dealer who will work with me on a trade in? ---- Appreciate your help, Thanks, Dennis
