A lot of the settings are common sense ....Then again , you can change them up if you like .....Some like the settings one way, and some like it another .......For example ....When I'm on the beach , I run a certain program that is pretty wide open as there are so many different targets that one might find on the beach ....I would not set it for high trash as there is not a lot of trash like parks would have ..... I would not have the recovery fast ON .....I don't need it to recover fast as there are not a bunch of targets .....I would have deep ON because there is a good chance that I am running a higher sensitivity in the sand on my beach because I can , and could also use the deep on as well as raiising the gain , so that the deeper targets will sound better .... .......On the flip side of the beach , we go to the park ....There is plenty of targets all over the place and the ground is full of trash .....I would NOT have deep ON because I'm trying to find good targets in the trash ....I have to get past the trash before I can go deep .....Recovery from one target to the next would be of importance to me because there are so many targets , so I would have Recovery fast ON ..... Trash Density would be HIGH ...... It looks overwhelming when you are starting off with the ETrac , but basically , once you know where you are going to hunt , you will already have a preset ready to go that has all these features already in it , and you will scroll to that preset , and hit the button, do a noise cancel and you're off to the races !!..... All the work is done , and presets are made BEFORE you start hunting ..... You will make programs/presets for various types of hunting that you do ...... A lot of the stuff is going to remain the same anyway .... You will try a lot of things in the beginning of owning the machine , but once you get thru the early stages , you will know how you want your machine set up for certain applications , and 90% of the time , you already have a preset all set up for that particular hunt !!..... It's like the radio in your car ....There are 50 different stations to listen to, but you already know the stations that you want to hear , and you hit the preset buttons depending on what station you want to hear ...If you want to hear country music , you hit the first button ....Easy listenning , you hit the 2nd button ........Same thing on the E Trac ....You have your programs already made up, and all you have to do is select them .......I fully understand that the entire menu looks overwhelming , but once you set the machine up , you actuallly hit less buttons and turn less knobs than you would on the Sovereign ....I'm serious !!.....
