What the different between First Edition 2012 & Second Edition 2015

I think i proposed this much earlier somewhere on these forums; but here it is again that i will repeat it:
ideal would be if some legendary model of metal detector is taken and analyzed in smallest details in such book.
Some model that "changed the history" of metal detectors.
From the coil, through front end, across the each possible stage in it, ending with audio out and speaker... if you understand what i mean?
Explained literary in each possible aspect... something like; " this resistor value is there because of... this capacitor value makes the signal to act as..." etc...etc...

The plan is for a more advanced book on metal detector technology, but your idea does have some merit, and could [possibly] be the subject of a different book. In many ways, the Raptor design in ITMD already satisfies some of the criteria in your request.

Alright, that's factually a truth.
But in addition i wold like to see complete disclosure of some legendary (yet obsolete and discontinued (for obvious reasons)) model which had influence on md industry or was (and still is) very popular among hobbyists worldwide.
Reading patents (obscure and mostly plain gibberish, just to fill the form of patent) is one thing but reading "human" article from ee "who did it" is quite another thing.
I find rather exciting to read such indeed rare articles and collect them on my disks.
Would be much better to have those organized and refined in form of a book.

To prevent exactly that; i made extra protective covers.
My book is still in very good shape.
Parts i want to reread again from time to time; i scanned.
That's the way how to preserve it for good.

Well I didn't have that chance, the binding on mine cracked/split on the first opening (I think glue was to dry or something), it was only a matter of a couple days till all the center pages fell out.

I'm gonna try to get another of the first edition just so I have one in complete solid condition to keep on my book shelf. The new one is on the "list to buy" as well..

You only need to correct manipulate with such type (paperback) of books:
