This is where it gets tricky because every device and phone app does this differently.
<h3>GPS phone apps</h3>
<p>
This should work the same way whether you have an iPhone or an Android phone.
<p>We do not have a recommended app as there is nothing we have found which quite does quite what we need. We are using
<a href="http://www.gpsessentials.com/">www.gpsessentials.com</a> and <a href="https://osmand.net/">OsmAnd</a> so try one of these first. If you discover a good app, tell everyone about it.
<p>
Visit the <a href="http://www.gpsessentials.com/">www.gpsessentials.com</a> website and read the manual (top left, on the menu bar: "Manual") for how to do this.
Except that the manual doesn't tell you.
<p>The OsmAnd documentation says:
<ul>
<li>"The simplest way to view a track you've downloaded is to tap on it in your device's file manager and choose to open it in OsmAnd. After that, you'll see the track in My places - My tracks or in the Dashboard - My tracks."
</ul>

<h3>Modern Garmin handheld GPS devices</h3>
<p>
Connect the GPS device to your laptop (or the expo laptop) using the USB cable. A folder will open on the laptop showing the contents
of the device.
You will see a subfolder called "GARMIN". Open the folder "GARMIN" and copy the file essentials.gpx which you
downloaded into that folder.
<h3>Old Garmin handheld GPS devices</h3>
<p>
These can only import cave entrance locations (waypoints) and paths (tracks) using the Garmin communication protocol.
This means that you need special software on your laptop in addition to a USB cable that connects your laptop to the Garmin device.

If your Garmin has a <b>mini</b>-USB socket, rather than the usual micro-USB found in phones, then you might have an "old" Garmin handheld, but some modern handhelds still use this old socket.

<h1>Placeholder</h1>
<p>This is not the page you are looking for.
<p>This will be replaced with the information you want as soon as someone gets around to writing it. Why not find out how to do this yourself ?
<h1>Charging your light (and phone)</h1>
<h2>Top camp</h2>
<p>Top camp has no mains 230V electricity.
<p>Top camp does have solar-powered car batteries, so you need to bring a <b>12V car-type charger</b> for your caving light and phones.
<p>At top camp there is one USB-charging socket (a pair of USB sockets) provided. This just plugs into one of the 12V sockets. Since this is not enough for everyone's phones, you need to <b>bring your own</b> 12V-to-USB plug-in. (Providing proper permanently-wired USB charging is on our to-do list.)
<p>USB to multiple-USB (e.g. 1:4) expander boxes don't work for charging lights. Even for charging phones they are very, very slow. So if you are using USB to charge your caving light <b>you must</b> bring a light charger which <b>plugs directly into the 12V socket</b>.
<h2>Base camp</h2>
<p>Base camp has mains power and UK-style 230V mains sockets as well as EU-style mains sockets. So your usual UK chargers will work and you don't need to bring any converter plugs.
<p>We have no permanent USB charging sockets. People bring their own mains-to-USB chargers so you may be able to borrow one, but this does mean that enough people bring one. So to be sure, <b>bring your own</b> (and label it with your gear tape).
<h2>USB cables</h2>
You need to bring your own USB charger cable for your phone (typically big USB to micro-USB). Yes, there are a lot of them about, but they are all personal gear. So <b>bring your own</b> (and a spare) and label it with your gear-tape colour.And bring a spare.
<h2>Phone recharging battery</h2>
If you are doing a lot of surface prospecting, and especially if you are using your phone for GPS location, you will want to bring a spare battery which re-charges your phone, e.g.
<a href="https://www.amazon.com/Best-Sellers-Cell-Phones-Accessories-Portable-Phone-Power-Banks/zgbs/wireless/7073960011">one of these</a>.
