Hi Mister Bee, In my opinion the only difference is the ID Edge has 3 pre-programmed hunt modes for Old Coins, New Coins, and Jewelry and notching. I would say they both have the same depth capability and sensitivity. Also I think First Texas is trying to liquidate present old stock and these and other models will be gone. I only have one NIB IDExcel and a 1236x2 left. I hope this has helped you. God Bless.
