EFFECT: The most impossible looking card trick you will ever perform! The spectator shuffles his own deck of cards and selects one (no force). He opens the prediction and it matches his card! The prediction has been on the table the entire time and never touched by the magician! Everything can be immediately examined!

This book begins with the original version of Duotech as performed by Bob Strickland for over 30 years. This is the time tested performance that Bob used to fool some of the best magicians in both England and the United States. You will also learn how to construct your own Duotech II, along with many variations devised after the release of these products!

The "method" on this is virtually identical to Duo-Tech II, but of course D-T II comes with some gaffs, this is just a booklet.

And there are some other methods in the booklet that don't use a wallet/notepad, but even with those, things aren't examinable.

I would rate this effect as good, but the description is very misleading.

It is virtually identical to Duo-Tech 2.

You can only use a borrowed deck if you can manage to get some time with it alone and remove a card from it. So you can't just ask a spectator if they have a deck of cards, have them get it, and perform it.

And, although the ad copy exclaims "Everything can immediately be examined!", that's completely untrue. The wallet/notepad can't be examined immediately (really, to be safe, at all).

I figured out the method from watching a couple of demo videos of Duo-Tech 2, so I find the claim that this fooled lots of magicians a bit suspect.

So, decent effect, misleading and exaggerated ad copy (which is much too common, in my opinion).
