SAN SALVADOR – Sometimes it is hard to get a sense of terrain and space while driving. You know you are on a road, in the desert, or mountains, or a forest. You know you are going somewhere, but the overall picture is indistinct, at least until later when you look at the map, your photos, your memories, and piece the whole thing together.
This is not the case for the road between San Salvador and Guatemala City. I had never driven the route in my own car but had taken it several times in a bus, from one city to the other and back again. Leaving Guatemala City you travel up and over the mountains through a misty zone of pines and hardwood, crossing the rim of mountains separating the two Central American countries. When you crest the mountains, you drop down to a hot plain that calls to mind parts of Texas and Mexico, distinct from the cool Mayan highlands. The highway is not straight but somehow feels that way. Up and over the mountains, across the plains and valleys, a stop at the border, across a river, and into El Salvador. The road continues on, close to the coast but never so close as to see the ocean, until you join the sprawl of San Salvador or turn off somewhere along the way.
GUATEMALA CITY — Is the dive watch still valid as a tool for scuba divers? The short answer is yes. It absolutely is. Before I begin to tell you why it is and why if you are a scuba diver you should probably wear one, first let me explain what a dive watch is. There are many “dive style” watches that look the part but are not. To really be considered a dive watch there is a series of standards (ISO 6425) a timepiece must meet including 100 meters of water resistance, a timing device (such as a unidirectional bezel) protected against inadvertent rotation, a certain quality of illuminated markers in dark conditions, etc. Before the advent of dive computers, a watch that could survive the water pressure, track the elapsed time of a dive and/or a decompression stop, and be read in low light, was an absolutely essential survival tool. It, combined with decompression tables, some good old-fashioned math skills, a submersible pressure gauge and an analog depth gauge (which tracks both current and maximum depth) served the same purpose as a modern dive computer. I find it somewhat ironic that most diving kits include an analog console with submersible pressure gauge and depth gauge but exclude an analog timing device. Now before anyone gets in a techno-huff, I absolutely believe in using a dive computer and I own two of them, the professional Shearwater Perdix with wireless Air Integration and the more recreationally oriented and smaller Atmos Mission One (so no scuba luddite am I). However, I also wear a dive watch while diving (and usually out of the water) and I think new students should be trained to use dive tables and analog gauges as well as computers.
GUATEMALA CITY– I remember my first time. That first time sinking under the water and thinking, I can’t do this, I can’t breathe underwater, and on faith in the equipment taking that first breath. The dry air flowed through the regulator and filled my lungs. I heard the hiss of the inhalation and the loud bubbling exhalation and then the next breath and for the first time was able to look around without the immediate thought of getting back to the surface. The thought that followed was, how long can I stay in this place? How long can I make this wonder last? It wasn’t very long, a few minutes, but longer than anyone can hold their breath. There were no fish, no coral reefs and no danger from sharks or kraken or marauding enemy divers. We were safe in the pool at my military school where an Army diver was giving a demonstration and a pitch for his specialty. It might not seem very exciting but if you have never drawn breath underwater then you have no basis of comparison.
