Remote coils, remote lines, & coiled remotes for paintball tanks
You can think of a remote line as an extension cord for your tank. This allows you to play without your propellant tank directly attached to your marker, so you can keep it in a harness or backpack. This also has the benefit of making your gun lighter on the field, which will aid your reflexes and mobility, and works with both CO2 and HPA.
See below for Remote Line Features & Tips.
Coiled Remote Features & Tips
The coiling on most remote lines keeps the line as snug to the player as possible, so it stays out of your way, while still giving flexibility so it doesn't hold you back.
Since a fair amount of players use their tank to brace their shots, you might find it more comfortable when using a remote line to add a stock to your marker.
Remote coils can be especially helpful for players using CO2, because they allow you to store your tank upright, which will prevent CO2 from spill out of the tank and into your gun.
Remote lines can have some variations. The most basic versions are essentially just a tube connecting the tank to the marker, but many coils come with extras that make the remote even more functional.
On/Off Valve & Quick DisconnectAn on/off valve is especially useful, because it lets you disconnect the line from your tank without too much excess venting. That means you aren't wasting shots, and is easier on your o-rings. A quick disconnect lets you safely disable your marker for breaks between matches without a lot of hassle.
Slide Check Valve with Quick DisconnectA slide check valve uses a sliding on/off barrel valve to disconnect the flow of gas. Once the valve is closed, the you can use the quick disconnect to break the link from the tank to the gun. Slide check valves have one drawback, though, as they tend to go through o-rings at a faster rate, though this is balanced by being faster and more intuitive than an on/off valve. Because of this, you should consider purchasing additional o-rings.
