If Warren Hewerdine has his way, the next hot item on children’s wish list for Santa won’t be a PlayStation, Xbox or Nintendo, nor will it be an iPod, iMac or iPhone. Hewerdine, who is the senior director of marketing for Berkeley-based Apisphere, is co-inventor of the Geomate.jr, a $70, first-of-its-kind GPS device that is shaking up the world of geocaching.
Geo-what? Geocaching is a high-tech version of treasure hunting. Geocaching relies on the same network of GPS satellites used to guide ships to their ports and cruise missiles to their targets to enable these treasure hunters, called geocachers, to find containers of varying sizes that have been hidden by others and recorded in an online database by their latitudes and longitudes. Armed with this lat-lon data, geocachers head out with their handheld GPS devices to find the hidden treasures, which usually consists of nothing more valuable than a few trinkets, if that much. But for geocachers, it’s all about the hunt.

Designed to make geocaching fun for kids.
And so today I went hunting with Heweredine. Armed with our Geomate.jrs, we headed off from the Apishpere headquarters near downtown Berkeley to the wilds of Cesar Chavez Park and the Berkeley Marina to track down the geocaches others have hidden there.
Before we left, because this was my first experience with geocaching, Hewerdine gave me a quick introduction to the sport, and showed me how much easier it is to do with the Geomate.jr instead of using a general purpose GPS device. Without going into details, suffice it to say it is like the difference between driving stick and an automatic.
Heweredine fired up his Geomate.jr as we were driving down University Avenue, and before I knew it, the thing started displaying distances to all the nearby geocaches stored in its internal database. To me, it was like looking through a magic portal into a parallel universe. I had passed by here so many times, completely unaware that these things even existed, yet here was this gadget telling me the closest geocache at the moment was just 90 feet away.
We had decided to start at Cesar Chavez Park, which contains several geocaches of varying difficulty to find, but because I was a novice at this, the first one we sought was a relatively large geocache that was not particularly hard to find. We entered the park, and my Geomate.jr indicated the target was about 1732 feet away in a northwest direction from where we were standing. As we walked, the distance displayed decreased, and the arrow started pointing in a more westerly direction, so we turned left at the next trail and headed down towards the bay.

Successful capture of my first geocache.
Like most GPS devices, the Geomate.jr’s accuracy is good to a radius of about 30 feet, and so when the display showed we were about 50 feet away, it became obvious we were going to have to head off the trail into the brush and then start searching the old fashioned way. The people who hide these geocaches can be quite tricky in their choice of containers and hiding spots, but in this first simple example, the much more experienced Hewerdine quickly found the old Army ammo box we were looking for hiding under a nearby bush. Inside were several trinkets, some log notebooks, a pen and a few other items. Fortunately, there weren’t any muggles – nosey, uninitiated spectators – around to bother us, so I simply signed and dated the log book, closed up the box and placed it back into its hiding spot for the next geocacher to find.
By its nature, geocaching is something best done unobserved by others. As geocaching has grown in popularity, however, there have been several unfortunate incidents of muggles calling the police after observing geocachers uncovering their hidden treasures and then placing them back. In many of these cases, the bomb squad is quickly called to the scene, and they subsequently blow up the geocache, even though most of them are clearly marked at such. Hopefully, as this sport becomes better known, people won’t find this kind of activity so unusual, or suspicious.

Nope, not under there. Sometimes a geocache can't be found, or is no longer there.
Our next attempt was not as successful as our first, and after checking the Internet with Hewerdine’s iPhone – cheating, really – we determined the geocache was probably missing, possibly stolen by a muggle. And so we next decided to try something a bit more challenging, and set out to find a micro-geocache, the smallest of the breed, and one that had been designated as difficult to find. Pushing the button on the Geomate.jr a couple of times brought up this entry in the built-in database, and the display quickly told us to turn around and head off in another direction.
And more difficult it was. After zeroing in on the approximate location with the Geomate.jr, we both spent the next 15 minutes looking under bushes, into trees, behind rocks, around discarded beer bottles and in other potential hiding spots with no luck. Hewerdine cheated again and checked the geocaching.com web site with his iPhone for clues, and found two hints associated with this particular geocache. We learned that whoever hid the geocache “would be nuts to give a hint,” and that it was in plain sight, but hidden. Nuts? What could that mean? Looking around, we decided that meant a pine cone. After another 10 minutes, Hewerdine, again, found the geocache, this time hidden inside a pine cone lying on the ground in plain sight next to a tree. In retrospect it should have been obvious, as this kind of pine cone could not have come from the kinds of pine trees in the area, and this is precisely the kind of experience that makes you a better geocacher.

Sneaky geocache hidden inside a pine cone.
Heading back toward the civilization of the Berkeley Marina, we decided to hunt for one more geocache hidden nearby. This one turned out to be the easiest to find, but it also showed how you have to really pay attention while hunting instead of just burying your head in the display and following the arrow. This geocache turned out to be at the very end of a pier jutting out into the bay. The pier is only about 50 feet long, but the Geomate.jr was telling me the geocache was about 60 feet away. You do the math.

When geocaching, be careful of long walks on short piers.

Geocaches can be hidden almost anywhere, and probably are.
Hewerdine is quite active in the geocaching community, recently attending the Geo-Woodstock VII gathering in Bell Buckle, Tennessee, where he mingled with some of the truly hardcore geocachers, and he has lead numerous local school outings to introduce the students (and most of the teachers) to the sport. Beyond the obvious goal of selling more Geomate.jrs, Hewerdine feels strongly that geocaching is an ideal venue for getting children off their behinds and into an outdoor activity that is much healthier for them. Families who have purchased the Geomate.jr are starting to “complain” they can’t drive anywhere without the kids screaming to stop the car so they can run out and find the geocache the display is telling them is nearby. And with 250,000 geocache locations stored in the Geomate.jr out of the box, the kids will be screaming for a long time to come.
