Lots to choose from there. Still a hundred or two from the Teknetics T2 SE or the Fisher F75, but the F70 is an awesome detector from what my own research is telling me. The Garrett AT Pro is one of the most popular detectors out there and is also waterproof which adds a great deal of diversity to the types of hunting you can do. The Tesoro's are rock solid machines, and the list goes on. The biggest question will be the type of hunting you are doing and your own preferences. The ergonomics are a little off on the AT Pro for my personal liking and the Teknetic's and Fisher machines are a bit more "chatty" than the Tesoro machines. The most popular of the Tesoro machines are "beep and dig" without a VDI. The best thing you can do in my opinion is research. Lots of good videos on YouTube showing the set up and use on most popular machines. Most of us seem to be VERY brand and model loyal, so remember that when others give their opinion. Though I do not own either machine, I will cast my vote for the Fisher F70 or the Garrett AT Pro based on your budget. Don't cull the idea of a used machine purchased from a reputable source. Best of luck.
