I had trouble with CZs in the park because the only info I could get was those three tones. Bing Bong Bing BONK. In another post you mentioned that "aluminum will eat you alive" with a CZ...that's what I mean.
I'm sure the CZ pros out there didn't get stuck at my level with the machine, but I just could not relate to the audio.
I preferred to hit that junk with my old original Bandido, which only had one audio frequency, but the info was there in subtle inflections of the single tone. I got half-decent at telling ring tabs, foil, etc. from good stuff. I would never mistake foil for a nickel, for example.
The Tejon, in my very limited experience, has the nice sweet distinctive sound on brass and lead and so on. I think this is part of their appeal for the serious digger.
I'm hoping the 1270 packs some distinctive sound characteristics in either disc or all metal that will allow reasoned judgements to be made about probable ID...crackles on iron, sweet sounds on lead, etc.
If I'm going to be digging holes deeper than knee-height--like Bill Ladd promised
-- I want to know if it is a Mountain Dew can.
I like the concept of tone ID and I use a two-tone Cobra II and multi-tone Mark 1 to get some of that, but what I'm really looking for for woods hunting is a deep machine with some TONE CHARACTERISTICS --even if only one audio frequency.
I'm hoping this is what the 1270 will deliver. Reading between the lines on other threads, it appears that it just might do the trick...
