Mobile/Cell Phones

Hi Everyone

any ideas if having a mobile phone in my back pack will affect my detector while I'm detecting?

cheers
 
Tip, leave it in your car or turn it off.
 
i think you are right only took it last 2 days and have had to back gain off 10% who knows what else its doing!
 
I don't carry mine afield any more. I always had the feeling that even off, it had an effect.??? HH jim tn
 
I have a version 2 and it is more sensitive to emi and electrical interference than the newer versions most places I cannot run at more than 50 % sensitivity. IN the gold fields 100% is not a problem as I am away from emi sources. My cell does not effect my unit. Take you cell phone call your voice mail and hold it over your detector lower it slowly to the coil. At some point the detector will pick it up as a signal just like any other piece of metal. I have never had a problem with my cell causing Emi on any of my machines. Even the higher frequency ones.
I hear this allot on forums but have yet seen anyone prove its a problem.
Food for thought try it for your self and see what happens. Maybe the reason you have to turn your sens down is emi interference due to locality. Power lines, transformers and underground lines all drive my GB crazy. Phones nothing? How the other Gbs can run at full sens indoors I don't know. But seems to me they should be even less effected. Please let me know what you find out. Oh and what phone you use. I use a military grade Casio Gz rock (Carrier is verizon) as I have dunked a couple phones by accident fishing I finally got a water prof phone. Dave J has said that this unit has the best front end he has ever designed Hands down. Front end means the signal transmit and receive. That means allot to me coming from him and knowing the units he has had a hand in designing.
It would be great if lots of us try this and with all the different units on this forum some might defiantly be effected and or the cell phone types might be found to be the culprits. Would be nice to be able to Id the phone most desirable for a detectorist.
HH Everyone
 
Good post. I have the earliest IPhone produced. I have a new GB Pro version 4. I have just started using it in local parks with the 5 inch coil. I keep the phone turned on in my left shirt pocket for safety reasons. (Los Angeles area). I have been running at 100 gain in both AM and Disc with no problems so far. One of the parks ground balances at 87 and the machine still runs great. John
 
yes i am unsure if it affects anything, but i did have to use lower gain the last few days ( beach) but its been a full moon with bigger tides so maybe the sand below is still wet hence the lower gain?

i think i will carry mine turned off just so i know its with me for what ever reason i may need it.
