I didn't have one when you posted in late December, but I bought a new T[sup]2+[/sup] last month and have made a couple of calls for verification to FTP about a two detectors I own, so here are some answers regarding the T[sup]2+[/sup] and my personal experiences with T[sup]2[/sup]'s and F75's.
First, I started handling the T[sup]2[/sup] when it was introduced in 2006 and ended up using four of the original T[sup]2[/sup]'s between then and mid-2014. During that period I also had an F75 Ltd. Both could get a little noisy in bigger cities or other places where EMI sources are greater. In the field, meaning out-of-the-way places such as homesteads, pioneer and military encampments, old dance hall sites or report sites. both models were not a problem to operate and were not really bothered by EMI. By the way, I run ALL of my detectors at full Sensitivity at start-up then reduce it should I need to deal with EMI and instability.
Since mid-2014 I have also owned four T[sup]2[/sup] 'Classic' models, including two of them a year ago, and I had another F75 Ltd. a year ago, and in the past six months I also had an updated T[sup]2[/sup] SE Ltd. In my house, especially in my TV Room or in my Den, every detector suffers from EMI! But taken out hunting, in town but a bit distant from nearby power and interfering sources, they all behaved just about the same. Perhaps a slight edge in less EMI with the F75 Ltd. and updated T[sup]2[/sup] SE Ltd. but nothing immense.
Fast forward to the T[sup]2+[/sup] which I wanted for a few reasons. One, I happen to prefer the Green color instead of the basic Black color. Second, I wanted the 'bP' function that was missing on the original and the 'Classic' model. But I was also curious about the DST feature that is selectable on the new release F75+, so I called to get a direct answer. Yes, the T[sup]2+[/sup] has DST, but No, it is not with an On or Off selector. It is simply designed-in and is permanently On in the new T[sup]2+[/sup].
In my house the new model, like the older versions, the updated version and both the F75 and F75 Ltd., all show the same noisy behavior. But when I get the new T[sup]2+[/sup] out into some of the local urban locations where I have used the F85 and F75 Ltd. and the T[sup]2[/sup] Classic and updated SE Ltd., the new T[sup]2+[/sup], like the two DST features 'Ltd.' updated models I had, is a little smoother. Personally, I live with it because where I usually hunt and am well distanced from most EMI sources, or away from transformers and power lines in urban locations, I find the new model is working just fine.
Since late '71 I have never relied on owning only one detector, and I usually have a few detectors that can complement each other. Also, I seldom, and I mean very seldom, use a 'standard' size search coil. My T[sup]2+[/sup] keeps a 5" DD mounted full time, and that's how most of my other detectors are set up. With their smaller-size coils for the trashier places I hunt. I do make use of mid-sized coils on some models and will be ordering a 10" elliptical DD along with another T[sup]2+[/sup] to keep both coil sizes at-the-ready. I do that with my Nokta CoRe and Relic models and a Fisher F44 that sports a 7" Concentric and the other a 5" DD. If I am in a locations where one model I want to use is really bothered by EMI, I simply select on of the other models I have brought along that has the least amount of annoyance.
Now, it's a little past 7AM, it will be daylight soon, and should warm up to about 45° but me mostly cloudy but dry, so I have my T[sup]2+[/sup] at my side here in the den and we're about to head out and have fun. Best of success to you when you get out yourself.
