With xi Eridani at the upper left of your field of vision you should see the two omicron Eridani stars just off centre. They resemble a faint version of Castor and Pollux (being of 4.0 and 4.5 visual magnitude).
Before passing through the 'narrows' here, you might pause briefly and study omicron2. The star, also known as 40 Eridani, is the primary of a triple system. Its ninth-magnitude companion, a white dwarf, may not be visible in binoculars, but it is easily seen in medium sized telescopes.
If your scope is large enough, you'll also find an eleventh-magnitude red dwarf gravitationally attracted to the white dwarf, making it one of the more compelling trios in the heavens.
Now -- with the naked eye or binoculars -- look to the southwest of the twin omicrons and you'll find gamma, Zaurak, a rather reddish star which also has a faint companion.
From Zaurak you climb once more, up to delta: fourth step.
