Ken, I had my DFX for 3 years now and hunted almost exclusively with it until April of this year, that's when I got my X-70. I did find many good things with the DFX, but not at any great depths. The best depth I got was with my Explorer XS but the X-70 is no slouch in that department either. How's a smallish button at 13" sound? The DFX is a good machine but as you know, there are many adjustments and when I wasn't finding anything, I would fiddle with them, try different programs and that wasted time. You can go out with the X-Terra, turn it on and once it's Ground Balanced (simple), all you have to fool with is the Sensitivity and maybe change Disc. Patterns, that's basically it. You spend more time detecting is what it boils down to. The X-Terra is stable too, and doesn't false nearly as much as the DFX. It's light, has a very fast recovery speed and is almost fun to use. You still have Tone ID if you use that and a large display. The only gripe I have about the X-Terras is they don't come with a rechargable battery pack, but 4 Duracells will last about 40 hours with headphones. So the decision is yours but I thought I would add my 2 cents worth. If you get one, you will want the 10.5 DD and a 6" coil, that lineup covers most site and soil conditions. Ron
