How many people think the GPS is giving you accurate location? Don't you know there is a WAR going on?
Do you believe the War Department will give "them" an accurate targetting system right on the retail shelf for direct application? Think again.
GPS signals have "changed".
In pease times, the GPS gives you 30 meter accuracy and more with differential, about 25% more, by slitghtly correcting the signal for the covered distance from 0 miles to 4 miles out for the super- tanker to come in. The corrective effect is good up to 40 to 65 miles, but gets modulated farther, or appears as an error. But in war time Falcon Air Base introduced a jumping beans instability ramping, plus or minus 100 meters. Try to find your wreck now, if you can. Better than 30% of the mature divers retained their LORAN-C computers, specially if they are NOT the China-made type. The American made product such as the SITEX-EZ-7 and the EZ-97, was made in Clearwater FLA.,
even today shows their 20 foot accuracy, as the best performing computers available, for the buck. However, the recent price today reflected this quality attitude. One EZ-7 just sold for $1,400.00 and the EZ-97 for $1,800.00. These units also translate GPS to Loran-C and back, and is one of the best cross-track directors made.
The Sitex in ON in 45 seconds anf fully navigating before you even leave the harbor. In the last decade, the "chinese" run, if ever, after a one hour warm up? Some GPS units take tens of minutes to two hours to aquire signal. I'm using Garmin GPS and EZ-97. If just used, it takes 5 minutes. You can flip on a 25 foot circle with Loran, and get proper heading. But yesterday the GPS, even after a 150 run, was heading South, and took the 400 foot run to re-direct the very expensive Garmin, as the Loran was on point. We dive late, the water is just fine, the camera worked fine,
had good time, no regulator freezing, and no waves to make for a bumpy ride. Out and back, right to the dime.
