If you use Firefox, download Garmin communicator plug in and install it. Then you will be able to download direct to the GPS

The benchmark is on this topo map: topo It is about equidistant between but south of OCO770 which I found, and OC0769, which I didn't.

I found it on an abandoned road bed, in southern New Hampshire, near the town of Epping. It's stationed on an old bridge. N 43 01.931 W 070 01.027 bridge

While searching for several benchmarks in a remote area, I found one that was marked on a topo map, but not in the NGS database. C48 It's clearly a USGS mark dated 1934. Is there a way to report this to the NGS?

I recently spent 6 trips up a deserted railroad bed looking for OC0397. It hadn't been touched in 60 years and was buried under mounds of dirt and debris. I finally used my metal detector and dug up the thing. OC0397

Got it. Thanks for clearing that up for me

If a data sheet reads: MY0279* NAD 83(1986)- 42 55 04. (N) 070 47 42. (W) SCALED MY0279* NAVD 88 - 14.109 (meters) 46.29 (feet) ADJUSTED MY0279 ___________________________________________________________________ Does this mean that the adjusted coords are N42 55 14.109 W070 47 46.29 ?

Thanks. I wonder why I didn't see that.

how do you delete some waypoints individually off the GPSr using GSAK? I have a number of found caches that I'd like to strip off the unit. Of course I could manually delete them one by one but am looking for a way to do this from the PC. I use a Garmin Legend.

BTW, I am a doctor. My infectious disease specialist says that one dose (100 mg) of doxycycline is for prophylaxis when you notice the tick bite with the characteristic red circle. One dose is about 75% effective, although some increase that by taking one dose a day for a week. This IS NOT for active lyme disease, only prevention after a suspect bite. I have had Lyme, and it is awful.

Up here in the northeast, it's prime deerfly season. Ticks and skeeters add to the fun. I recently bought a mosquito net hood for when the dadgum things really get vicious despite bug spray. If they are bad when walking to a cache, they are ferrocious when you stop to close in on a cache, or write in a log. Putting the hood on really saves my sanity. (I look like a dadgum burglar, but who cares out in the woods?) Deer ticks are everywhere here, and I get bitten at least once a week caching. I had my doc write out a script for doxycycline 100mg, and keep the bottle at home. Whenever I get one of those red welts from the deer (Lyme disease)ticks, I take one. One dose after exposure is all that is necessary to prevent Lyme disease according to my doc.

After getting a strong satellite lock (may take ten minutes or so at times), I keep holding the unit flat at all times. There are some times when the sats are just not aligned good enough for dense tree cover, though. You wqnt at least two, preferrably three, in the center. When I get within a 100 feet or so, I keep checking the bearing to the cache and mentally note it, because if you stop moving to look around, the heading indicator may start tp wander. If I lose the heading function, I get out my compass and keep following the last known good bearing to the cache. I pretty much use the compass for the direction at the end anyway, and just check the distance at that point.

It's now summer and the tree cover in NH is quites dense. I use a Garmin Legend but have been unable a couple of times to follow a track to a cache in deep woods because of poor signals due to the tree cover. Any suggestions how to improve my reception?
