EMI

[gabbyhayes]

My wife just got one of those little LED flowers with a solar cell to charge a little battery. It is besides my test garden, and it really drives my detector nuts!
I wouldn't have expected it to be a major source of emi but it sure loves to mess with my detector.
It pretty much makes the CTX unusable within about 5 or 6 feet.

Does selecting other Noise Cancel values increase or decrease the EMI noise?

Are you running in manual or auto sensitivity? One place I have problems with EMI, I have found that switching to Auto Sensitivity, almost totally eliminates the problem, leave it in manual and it falses until I am past the source. Doing a frequency scan does help out in manual along with lowering my sensitivity although switching to Auto allows me to hunt in that area easier.

Wow, that is surprising with a small lawn ornament. I have detected underneath power lines and only noticed slight interference. I have detected right up next to an electric fence around horse paddocks (it was on ) and did not notice any interference. However, I have posted in another thread that at a local ball field, there are times when my detector is almost useless. It will be working great then all of a sudden it freaks out. It will least for a short while, 10 min or so, and then it stops and all is back to normal. I have not been able to figure it out.

I find the CTX more prone to EMI than my E-Trac ever was.

Last spring during a trip to the UK the were running high frequency over the regular electric lines buried and over head and it was a nightmare for all brands of detectors! It would be fine and all the sudden complete shut down not a pleasant experience when you can't control it!

I tried detecting an old church awhile back but my Explorer wouldn't settle down at all. This church was in the middle of nowhere with no power lines above or below ground. I couldn't figure out what was causing all the interference. The next day I was told the whole lawn had just been sprayed with fertilizer. Never heard this could cause problems but it's the only reasonable explanation for that location. Any thoughts?

Here's a thought around here they burnt a lot of coal so when they cleaned out the Klinkers they threw them out in the yard and they are Hot rocks on steroids Turn down your sens in manual and I enable salt to smooth out the chatter then concentrate on repeatable signals. Good luck

How far is it to the nearest cell tower? I can't get within view of them or they make it impossible to hunt.
