hi all, i am currently looking for a deepseeking md, able to cope with heavy iron trash (small) and consider a 1236x or a 1270. anyone familiar with the differences between the two? the fields i hunt are roman (lots of mineralisation and small iron junk)and the new line of tesoro which are usually used for these fields are just not deep- seeking enough. thx, jack

1236 vs 1270

Jack,
I doubt the 1236 would do any better than the Tesoros on depth and probably a little less on the small silvered but it will do well in the small iron. I'd grade it a tick better than the C & V for iron see thru. Depth on the 1270 will vary depending on the type and amount of mineralization due to its having a preset GB in disc mode. Small iron is no problem for the 1270, it handles it much better than the 1266 for example. it does take a little while longer to get used to the 1270 vs the 1236 when hunting iron trashy sites at low disc settings as it is noisier on the disced out iron but not too bad when you get accustomed to it. Just something you gotta put up with on most deepseekers nowadays.
When you say "lots of mineralization" do you mean the the preset GB machines like the Cibola loose a lot of depth? I have seen other UK detectorists use that phrase when it seems to mean something other than what we consider bad iron ground over here.

Tx for answering my question. as to your question: the problem with the tesoro's is that the factory used to concentrate more on discrimination than on depth. now that they "beefed up" the power, they seem to get better depth on mildly mineralised soil but tend to get unstable, thus forcing you to use less sensitivity. I wonder if anyone was looking for that solution, since in Europe, most interesting sites contain a lot of mineralisation caused by both iron particles, bur also by composted garbage etc, thrown on the land for centuries. BTW: the newer tesoros have one more questionable improved ability: they are so extremely sensitive that you dig all kinds of super small pieces of lead. the older tesoros were also the preferred MD because of its good disc and ability to cope with mineralisation. the older fishers (like the 1266) were not used often on these sites because of the loss of depth and the "poorer" disc. from what i understand, the 1270 and 1236 should be better in coping the mineralisation nowadays, thus making them worth a try over here. on the other hand: i do not feel like digging deep iron, which i do now with the cibola. anyway, your answer seems to lead me to to the conclusions to buy a 1270 (BTW: i have used a 1266 for a few days at a roman site, and apart from the problems it had with all the rusted roman nails i did find a very nice roman brooch then).

Perhaps you should consider the ML Advantage. According to all reports it handles iron mineralized ground as good as anything going here in the states. In ground that forces you to cut way back on the HOT Tesoros it is reported to run smooth and deep. You will give up some sensitivity to the small stuff. I think I would go that route and include the 1236 for picking thru the areas with a lot of small iron. When it comes to seeing small low conductors in iron where depth is actually a hindrance I can tell you for a fact that the 1236 is one of the best. If hitting the tiny bits is a concern you might want to rethink the 1270 as Its every bit as sensitive as the Tesoro's to that stuff. However, you can make use of the expanded iron disc mode to fine tune it to reject most of the smaller bits. It very much like the progressive disc the Cibola has in the iron/foil range but even more so.

i ll stick with the 1270 then, since i understand its a bit deeper than the 1236 (correct me if i am wrong!). i own a minelab sov GT for relichunting flooded medieval villages that turn up at low tide. NO MD can match the sov there, esp. since PI MDs are unusable, due to the iron and salt laden bricks still abundant there. i trust the sov on wet sand, but i NEVER use it inland. in my opinion its just no good inland. i have been thinking about the minelab advantage but read some reports that its keen on iron, esp. deep iron. thanks a lot tom for thinking with me about this one. as soon as i get the 1270 i will be taking it out and i will let you know if i am pleased with it.

situation trying to cope with iron plus the mineralization factor. Be sure to get the 5" coil for the 1270, as it helps immensely. I have done well "cleaning up" after the Lobo ST with that combo. 
Let us know how it goes.

The 1236-X2 to me works better in the iron infested areas. As far as the mineralized areas the 1270 would be a better choice as it does have a manual Ground Balance. Either detector will take some getting use to and the 1270 is a little more chattery than the 1236. When you figure the 1270 out you will do good with it. HH, Ron@ Dixie
