Quattro, depth ??

[dimeaday]

We have a 5 acre park, that was a brick yard in the 19th century, WPA turned it int o a park with a pond, more recently pond was filled, ball diamonds established.. most of the dirt has been shoved around, fill brought in.. I have found the clad and alum trash, small amount of silver and wheats.. usually running the machine in relic or all metal with the sensitivityas high as it will go without a lot of chatter..Since the ground thawed and is very wet, I get quite a few deep targets registering solid 37-38, very high tones. Dug on 3 of these yesterday to 12 inches, target is still there no change, but its tough to go deeper with a hand trowel and keep things neat,.. In the past i've dug a few small very old iron or steel targets that register this way. Anyone run into anything similar with good results..Finally turned the sensitivity back to 10 and did the 4 or5 inch clad thing.. I left the deep targets without retrieving it..dlil

had a similar experience the week before last with my quattro. got a good reading in the mid 30's so dug down 10" still getting the signal so dug some more till i got to clay (18") normally I'd have given up thinking it was a rogue signal or whatever but decided to keep going as there are the remains of a temporary roman fort in this field. eventually had a hole 3 foot by3 foot and almost 4 foot deep when my spade struck metal.
cleared away the loose soil and found myself staring at an 18" natural gas pipeline !
as i straightened up from the hole, i noticed a gap in the field hedge about 200yards away exactly on the same line as the pipe, wished i'd seen it sooner !
i did have a chuckle to myself at being suckered and it wasn't till the hole was filled and i was heading home that i realised i should have taken a reading off the pipe to see what it registered. looked to be a regular steel pipe with a bitumen type coating and according to locals, put in about 25 years ago.
on a different note, i kept thinking i'd bought a bit of a lemon with the quattro, was hoping it was gonna be a cheaper version of the explorer, but read posts on the web about slow recovery etc. i was at a rally on sunday with about 200 other detectorists and whilst searching a stubble field i was clearly walking over others footprints and still managed to pull out some finds they had missed.
once you get used to all that chirping (like a canary on heat) and a bit of falsing on iron occasionally i think its a capable machine. not sure what the difference is with the safari tho.
ps I detect mostly in all metal (farmland) but go into coin with pulltabs discriminated out on playingfields.

Have found this machine to be truthful on good solid high tone hits. I'll get one of these deep ones somewhere, other than a park and take a shovel to it, hopefully it won't be a gas line..dl il
