Well, I am only a few months old to this hobby and my Outlaw, but so far I have to say that I do not think the Outlaw is a great choice for a strictly coin-only machine. No doubt the no-motion all metal is a benefit for relic hunters and in my experience the Outlaw goes pretty deep. However, I have not found a difference in the sounds of deep bent nails, beaver tails, and coins. Bent nails and beaver tails will often (very often) not Disc out on this machine if they are over 4" deep (at least not in my very mild/neutral Idaho soil). Thats a BIG deal if your concentrating on fairgrounds and home sites. I do most of my hunting with the 8" donut coil so the 5.75" might help with this. I have only a few hours on 5.75 in tot lots and haven't found a big difference betwwen it and the 8" coil, but that's a small sample size. In my limited experience, the Outlaw finds a BUNCH of stuff, much of it well into the 8-12" range, but it has problems letting the user know what it has found prior to digging and has problems ignoring what the user asks it to - especially old pull tabs and any iron bigger than a fingernail. The only clue I have managed to get from it is that if Im into the 9-10" range and still havent located my target, its likely an iron nail or similar sized ferrous item (however, see Stix's recent post regarding target ID using super pinpointing). But its hard to dig 9 inches on a solid sounding target and simply give up! It has NEVER been a coin (out of several dozen digs at that depth) and Ive had the disc maxed out on some of them with a good signal still being sent.
I'm really not trying to bash on the Outlaw, I'm just trying to give an honest opinion on what I find to be a shortcoming if one wants to specialize in coins. Its a great all-around detector, but there has got to be other better Tesoros that target coins only. For instance, I used my wife's Silver uMax when the Outlaw was getting a check-up and I found i could tell differences in audio response of coins vs iron much better with this machine. The Umax seemed (again, only my perception, not an empirical study) to ignore the pull tabs a little better too. I also didn't see any difference in depth, but that's pretty hard to compare when only using one machine at a time and with only a 40-50 hours on the machines combined.
Anyway, I hope that helps with your decision. The Outlaw is a pretty cool machine IMO, but I'm not sure Id buy it with a coin-only agenda. Ive got nothing to add regarding the Tejon, only that Ive been wondering about it myself...
