GPS tracking.

Post by Easylife » Fri Mar 01, 2019 2:20 am

On my permissions I always use GPS tracking and plot the older finds (over 300 years) which may then later show some pattern and warrant a much closer look at that particular area. GPS tracking is convenient and quite good but still does not compare to the accuracy of searching by string lines or similar as some targets will always easily missed.
Use it knowing it's limitations, It's great for highlighting areas that you have not covered but really really thought you had. :D ::g

I used mine and plotted stuff for 2 odd years.... great I thought.... found something of interest at club meet Flo said where did u find it....I said I can do better than that I can give u the position......came out with all the gumph .....o u don't use that one u use the other GPS setting so no good to her at all rl; so make sure it's on the setting they use :D .....silly Billy

I never use gps for knowing where I have detected as for me there is little point. All of my land is pasture and even if you string it out you will never get it all the signals with a single pass. Slight changes to the detector settings, angles of approach, the moisture content of the soil, EMI or, for all I know, the allignment of the moon with Jupiter seem to throw up more signals.

Even when a field eventually becomes quiet it is possible to turn a few of the iron signals into targets by judicious winkling. After that you are probably best advised to try another field while you wait for the technology to advance a bit.

Besides which I enjoy my random strolls in the countryside. :D

Grid reference is the preferred format but any can be easily converted to it. You still had the correct location saved whatever format it was in. ::g

I've been GPS'ing my trails and finds for some years now. I find the signal isn't quiet accurate enough to follow straight lines so I grid the areas with my marker sticks as I go. I then do the same site again at right angles. It can become a bit boring so always do a bit of free walking and go over the hot spots again.

As others have said, plenty still gets missed due to ground conditions etc. I mainly do this on pasture, but have also been slowly doing it on my one arable site. Arable needs re checking as ploughing brings new stuff up.

I have recently upgraded to the Garmin eTrex 20 so I can overlay the 1900 map on the device so I can have a live map of the old footpaths while in the fields on club digs. I found seven coins along the original footpath on this site.

Another reason I like to GPS find spots is over several years coin hot spots can come to light, and makes re visiting those spots easy.

Most of my land is perminent pasture also but I find it especially useful for reference when I return to land that I've not been on for quite a long while. Of course ground conditions etc will affect target response but the majority should still be caught first pass so it helps to know where you have and have not been. I wish I had started using it on my permissions right from the start. :D

Yes they use a weird format :)) , can convert it to their one using this web site

A GPS device is also handy to install polygons on, this part of the site used to be woods, now all pasture, there are very few finds in the old wood section so having this available while detecting helps keep you where you want to be.

Old map (1960's) overlay with a current map shown.

White line is an old footpath (1900's), yellow is a field boundary and cyan is the woods line.

Well you'll certainly not miss those fellas - they put my smaller discrete white plastic sticks to shame. :D ::g
