Newer F75 and EMI

[cometguy]

Any of you who know me know I love my Camo F75. I was on board as soon as it was announced and couldn't wait to get my dream relic hunter. I love the weight, balance, feel, and my results. I love the Camo being a limited thing and not seeing a bunch of them. However, I will admit that I have learned to take a back up detector along. Hunting with my club buddies I have found a few places where other detectors or general EMI made the F75 useless. I have also learned to embrace the noise and hunt through it when possible. My F75 is my go to detector. The one I trust in well manicured lawns and tough situations to tell me what is in the ground. My question now is - - - are the newer F75s better about EMI? Surely there are those who have owned both and hunted in the same areas?

Don,

It is a great question. I have never been able to crank up the sens without receiving too much information. Maybe the later versions were tweaked.

Don,
This is my experience...bout a year and a half ago I bought a "used" F75ltd...it was sooo bad due to emi interference in some area's I couldn't even use it so I finally sold it...3 months ago I bought a brand new F75ltd and have yet to find a area I can't use it in...now I can't crank it up to full sens in some area's but you know with the F75's you don't have to run full sens to achieve great depth.....now maybe I had a bad coil with the first one I don't really know....all I know is the 2nd one with a little tweaking works fine in the area's the 1st one wouldn't...

Don,

I keep thinking about sending mine to Fisher for a checkup. It is my goto detector so I hate to let if out of my hands even though I have a F70 and a Deus. I don't have the threshold figured out on the F70 but I can change it and reduce a lot of the flakes and small bits from responding. Some opinions are that the threshold has a large effect on depth.

I have read where the newest models have shielding which helps with EMI....Owned original F70 and F75's and well EMI turned me off and never ventured into newer models but will say my new F5 has little or no EMI problems...Might give them a call for clarification...

well i must say that my new f75se is much better with emi than the f70 and the t2se that i previously owned. i hit a spot yesterday that both of my older units where almost unusable this spot has underground power lines running through the end of a small park, the new f75 did much better i was able to run it with the sense @ 50 there both the other machines i had to turn the sense down to 25 to 30 hh

Well-regarded detectorist Keith Southern says he was told that FT figured out how to lick the EMI issue when a cellphone tower went up right by their factory.

Don't know if it's true or not. But it does seem like something has changed for the better. There are certainly a lot of reports from experienced users that the newer FT detectors are running much more smoothly than the older ones of the same model.

I did not state that right the prior message. The New F75 LTD does not air test as deep as the Camo unit did on a dime. About 1 1/2 inches difference.
The F75 LTD hits all targets in test garden the same as Camo did ............ yet it does not have the EMI like the Camo did.
It was very erratic ( CAMO) unit...... In the country far away from all electronic operations the Camo was fine..you could not use it at any schools where Puters were in operation or Micro wave antenna were on the roofs.

It would hit targets though and hit them deep..if you could stand the noise level... Constant popping and cracking. AT 45 sens it ran smoother and would still hit dimes to 6 1/2 inches....

Bp mode was another story on the camo.. Just could not get it to settle down at all.... May have been a bad coil...
