First off the Berkut is one of the best ID screen detectors I have used when it comes to locating and ID'ing Canadian clad coins.
Most Id machines have difficulty with the with the coin composition being a nickel plated steel type coins.
The tones are the best I have listened to, they are pleasant, not irritating that get on your nerves.
You can customize the audio dept. to the extreme, way more than most can imagine.
The Berkut is as deep or deeper than the Etrac depending.....
The detector as a whole is customizable to just about any situation and to individual liking, it's one you can make it just to your liking.
You want a Tesoro adjust it so. You want a Minelab, adjust it so. Want a relic machine, or a coin and jewelry machine.It can be what you want it to be within reason.
Download the manual off my website and you'll get the scope of what you can do with it.
Coil frequency 2khz to 25khz. Wide coil selection.
Plus you are able to update your software thru your computer if you computer literate.
The 4 factory preset programs are perfect for the new user if the Berkut. Once you learn how the machine works you can start playing with all the parameters and
extensive sub-menus for all metal and disc modes.
Think the best way to describe the Berkut is its like a high end digital camera with countless menu options. Kind of like driving a Rolls Royce on a Sunday afternoon.
The Sorex menu system is not as extensive from what I can see, perfect for the fist time AKA user as it is also mentioned by others. It runs like a fast sports car on tight twisty mountain roads.
Just an all around faster machine and better in trashy areas. Most get the Sorex.
The Signum is for those that want the fastest deepest machine who think they can use all the horsepower, adjustments have to be more precise to use it.
Anyways, these days I like trying products outside the mainstream. Tired of the same ole stuff. AKA machines seem to bring back excitement into detecting. You actually have the power to control
how the machine behaves and functions.
The Berkut is one I have meshed with, as a target screen ID machine. I like it, many may not.
Added note the Berkut has an interesting hunting mode called analog, it operates like a digital camera that shoot RAW file photos. Completely operates and responds raw mode, unprocessed target signal.
It's up to the user to determine and let your brain process the raw information. Kind of cool.
Not trying to hype or force anyone to buy and try. If you would like to try something different.......take a look at these detectors. Read all you can about them, watch all the videos.....then decide.
The AKA Sorex is a good alternative to the Minelab E-trac, some like the Sorex much better and some may say they like the E-trac better. Personal preference.
