gamma 6000: very satisfying once you get use too it.

[johndoe1]

I've had the 6000 now for a few days, in the beginning I admit it was frustrating. I knew it would take some time and I'm still learning. But I must say I'm a very happy customer and glad I purchased my gamma. I've read some stories about people finding a couple coins next to each other and their detector id'd them both and didn't expect to actually have that happen to me, being still new to my gamma.

I do have one question I haven't figured out yet, if some one reads this and knows the answer please help me out. As I'm sweeping some times I get a real faint high pitch and a loud high pitch ding over a object and some times when I swing back over that object I loose the loud ding and only get the faint. Volume set to Max, in disc. Mode with iron and foil notched out, sense at 80-5, it's a very distinct and noticeable difference. It's almost like what you would hear on a speaker with a loose wire, lose of strength, not cutting out.

I would guess you are getting iron wrap aka the eddy currents on the edge of an iron target, since you have it notched it is attempting to remove the iron signal, but the edges do odd things to the signal so some makes it through the filter.The best way to figure it out though is to dig it all up, until you figure out what each target sounds like. I've only had my omega for a couple months and still am digging up pretty much every target, sometimes you get lucky and have a good target next to trash and you will get two tones.

I ran into this scenario not too long ago. I was hunting a trashy park and had dug a few pull tabs when I got a signal that started as a faint high tone and was consistent in one direction of sweeping but when sweeping the other direction got a combination of high tone/pull tab but was also a consistent signal. The depth was at 5" and I was running sensitivity at 65(due to some EMI:veryangry. I dug the target and found a pull tab then swept the coil back over the hole again and then the high tone came in crystal clear and about an inch further down was a quarter. I was impressed to say the least but more than that got an important "hands on" lesson.

just to give you guys a heads up, if you ever get a deep 40ID reading on the faint side and target is small dig it, i have found 8" dimes with this readings for some reason?

 

[ramairnut]

WOW! 8" and a 40 ID huh? That is weird but good to know. If I get a faint high tone, I will just crank up the sensitivity and swing over the target again and verify it. I read somewhere, maybe here, that a 10kt ring can hit at a solid 40 also if I remember correctly.

Thanks every one for the info. When I air tested a gold ring, men's its I'd was 59 , 24k. I thought it was possibly iron wrap. And thought about digging it just to see but didn't. I will next time though. I found a large rock today lol that threw me for about 20 min. Couldn't figure out where the signal was from, didn't figure on the rock. About the size of a ostrich egg, little bigger and heavy, not sure of Id off hand but i did keep it just incase it might be a meteorite. Thanks every one,

 

[ramairnut]

Meteorite=$$$$ Hope you have one there.

 

[johndoe1]

Yeah me too lol. My older MD found alotta rocks that give a solid tone, but my gamma wont on them, I wish I had remembered to bring it home to study it but forgot it in my dads truck, so tomorrow ill post its Id, weight and what ever. Thanks ramairnut for all your help. As I'm becoming more use to the gamma all I can say is good stuff, except like you said about the EMI, I found out today just how sensitive it is. And figure this is part of my problem in my yard.

I agree with Ramairnut totally, with the exception: any time its 10K its always a 60 no plus or minus! That my friends is how you know! GB it out everytime 1ST.You'll see what I mean. Bottom line is this....... 10K solid 60( no matter which direction you sweep) or..... pull tab! HH,

Bad memory on my part LOL:blush: A 60 makes more sense for sure. I just really wish the Gamma had a frequency shift to help with the EMI. I guess the Omega 8000 has this adjustment. Overall, I really like the Teknetics brand of MDs. My next machine will most likely be the T2 unless I find a killer deal on an Omega 8000 as I did on my Gamma.Gonna have some good weather here for the next 3-4 days so I will be going out to hunt and take advantage of these nice days while they are here. Then comes the dreaded wait over the winter:veryangry:
