OK- I'm getting a little on in years and love my Ace. I've finally decided imaging is for me. Do I understand this correctly? The 1350 DOESN'T have DSP like the 1500? Finally, would smaller than coin-sized targets show up as coin-sized on the profiling of the 1350? Also, I read in the reviews that the 1350 isn't as good on nickels. Thanks, guys & gals.
