I think Strawberry was more on about collisions.

Ahh that makes more sense good idea

Not sure if anyone suggested this but you can buy clamps like those used by clampers to secure your car. Sure i've seen them somewhere!

Both of those take longer to fit than a scrote would take to remove... Keep an

Look for a sold secure rated one if buying.. http://www.towsure.com/product/Neme...argetid=1666233605&gclid=CO34tbzq4rcCFVMetAod 0 esAmQ



Many of the caravan mags do regular security reviews

GPS ghosting from buildings. You serious? GPS is straight up, nothing moves sideways with a GPS signal. If a building blocks a GPS signal then it blocks it, it doesn't start bouncing about.

Actually, it can - and does.

GPS is NOT straight up, unless you happen to be standing directly underneath one of the satellites. However, your GPS position is calculated on your relative position from several different satellites at a precise moment, by calculation the signals sent from several satellites in different locations, and therefore at different lines of sight / angles (including sideways / diagonals).

Also, "GPS signals", are effectively just radio signals (broadcast on 1575.42 and 1227.60 MHz IIRC) - these 'bounce' (scatter, is probably a better term) like any other radio signal.... however while it is indeed true that the best signal will always be with clear line of sight, it's still possible to get a useable and (fairly) accurate signal when there's obstructions in the way - it just takes longer.

For example... go get a hiking GPS, switch it off / take the batteries out... go to the middle of nowhere, into the middle of a forest if you like or somewehre else with no clear view of the sky... stick the batteries in and switch it on.

It'll take a wee while, but it WILL get a fix of some sort, and in most cases it'll still be accurate to ~100m.

To block the signals out completely, you need to be somewhere the radio signals cannot get to - like sitting inside a faraday cage, or something

Most hand held GPS receivers do not work in a wooded area even my t eye looses fix in the woods....

My Garmin GPSMAP62stc does. My old ETREX worked fine too... in fact, even my iPhone works (mostly) fine. I can name a lot of other handheld GPS devices that will work fine too.

I do a lot of Geocaching in my spare time, which often involves walking around in woodland / forests, never had any issues.

It's not the equipment thats the issue, it's knowing it's limitations and how to use it. The same can be said with people that get lost on the hills, even with a GPS.

Yeah well my road atlas works on the sh!tter

And if you run out of bog roll...you can still use your road atlas

(The GPS error is multi-path. And tge frequencies are right L1 and L2 are their designations - L2 being the military band with no option of Selective Availability [which they did turn off when they realised there was a very easy way to get around it where it most mattered]. The Yanks also claim it is accurate to within a few centimetres)
