This is the second reincarnation of Delco Magneto:
- Version 1 was accidentally hurled to its death
by e_gadgetgeek.
- Version 2 disappeared, likely stolen and was
archived.
- Version 3 has an additional stage and is now a
microcache. What was originally the final (and evidently
"not-so-good") hiding location is now a second stage with
coordinates to the final stage in another park.
Some important info for your mission, should you choose to
accept it:
- This cache requires a compass and
basic compass skills. A compass with a rotating
dial is best. Even if your GPS has a built in electronic compass, I
recommend you use an "old-fashioned" compass instead.
- If you don't know how to use a compass, try this link:

- This cache may be time consuming. Probably not a good cache to
tackle on your lunch hour.
- Best attacked with at least two people
Let's get started...
The second stage cache coordinates listed below
have three significant digits removed.
The missing digits are represented by variables A, B, and C.
In order to obtain the values for these variables (and
ultimately get the final coordinates) you must walk a prescribed
course which, once completed, will reveal the missing values for
A and B in the form of
track log art. Value C is the
average of A and B.

-
The starting coordinates are for a drain grate in the middle of
a grassy field where you'll have plenty of room to walk around in
circles and look silly to the uninitiated. You can perform these
steps just about anywhere really but this particular location is
close to the second stage for convenience.
-
Reset the track log in your GPS. Enable track logging if it is
not already turned on.
-
Refer to the table near the bottom of this page for heading and
distance instructions.
-
Set your compass dial to the first listed heading, turn your
body in place until the North index line and compass needle align,
and then walk the heading the prescribed number of paces.
-
Once you have completed the first leg, dial in the next heading
and walk the prescribed number of paces.
-
Repeat Steps 3-5 until you complete the entire course.
-
Once you have completed the course, zoom your GPS display in or
out as needed to view the entire path you just walked. You should
be able to discern values for A and B.
-
Calculate C using the following formula: (A+B)/2.
-
You now have the missing numbers needed to complete the second
stage coordinates. The second stage is a tape marker affixed to a
stationary object that records the final coordinates.
-
The final cache is in a different park. It is a backup tape case
with a small log book. Bring your own pen. Since you're in
the neighborhood, why not bag Ushio's Portal too?

Helpful Tips:
- Ask a helper to escort you and call out heading and distance
numbers at the completion of each leg.
- Your escort should carry the GPS too. You should be looking
only at the compass and counting your steps, not trying to guess
what you’re drawing as you go. If you get distracted and lose your
place on the list, you'll have to start over.
- Walking slowly with short pauses between legs will greatly
improve the quality (and readability) of the track log.
