I hunted with the previous version of this detector, the F2, and had a blast plus found several thousand dollars worth of clad, coins and silver and gold jewelry.
It looks like this one has all of the same abilities plus a few more features on top.
Lots of detectors out there nowadays and I am sure you will get all kinds of advice about buying many including many that might tell you to save up more and get a more advanced tool for more money.
It looks like you have some hours under your belt but this could still be a blast to use, maybe different than that Time Ranger but how different I don't know.
Could be the same...or better.
It uses AA batteries, sips power and is weatherproof so all nice features among others.
I already had an upper end detector when I bought my F2 just to take on vacation with me.
After I got it and started to use it I found it was so good at what it did and was so much fun to use and found me so much I made it my prime detector for over 3 years and sold tons of them for Fisher after people read about what a so called "starter unit" could really do and posted about what I found.
I assume this Fisher would be no less capable.
When I decided to upgrade I stayed in the Fisher line and went to an F70/Patriot model because I learned the Fisher language so well.
If I was just starting in this hobby and had a certain low price point I wanted to stick to I would be looking hard at this one, too.
Here is just one review on one site about the F22.

Another to consider is a Bounty Hunter Land Ranger Pro which is aka the Ameritek Liberator
Also a very great value if you can pick one up at a similar price.
All of these are cousins, different labels but under the same company banner, First Texas, with a lot of the newer DNA features running through all of them.
