Okay, I know this won't end all questions, but it should help eliminate most. The most common question about remotes is "will X brand work with this type of air?" All remote type systems, whether they are coiled or steel braided hose, serve one main purpose. That is to transfer air from an air tank that is not directly screwed into the air source adaptor (ASA) on the marker. It does not matter what type of air source you use, the end result is the same. You can use carbon dioxide (CO2), high pressure air (HPA), or low pressure air (LPA). After all, gasses don't care how they get to their destination. All they care about is that they get there.
There are benefeits to using a remote line. First off it makes your marker lighter, which can be a big plus if you are using one of the larger tanks on the market. Second, depending on what kind of marker you have, it can make the marker more balanced. Another benefeit is that depending on what style of stock you have, it makes it easier for you to use your stock. Myself I have a collapseable stock on my 98 Custom. Without my remote I have to have the stock fully extended, and my 20 oz CO2 tank still sticks out from the back. If you are using CO2, it can act as a type of expansioin chamber. However I would still put an expansion chamber on a marker if you plan on using CO2.
There are also downfalls to a remote system. If you do not have a stock you cannot steady your marker against your shoulder. Another is that you might not get as many shots off your tank as if it was on gun. this is not a big issue because in my experience it is only around five shot differance. Also it can be difficult to switch hands, but with some practice it gets easier. Lastly if you are going through some real thick alsmost overgrown brush it can snag on a branch.
There is also maintance that has to be done of the remote line as well. After every day of play you should wipe down the hose with a damp cloth. There is an o-ring on the part that screws into the ASA that should be checked often for damage. Most remotes sold have a slide check valve on them. This is a part that slides. There are two o-rings on the part that slides that need to be replaced if it starts to leak.
The only tools you need to replace your o-rings are two wrenchs. I use a pair of vise grips and an adjustable wrench. Remove the quick disconnect coupler and pull off the slide cylinder. Use a dental pick or small allen wrench to remove the o-rings. Replace them with new ones. They are just standard tank o-rings so they are widely available. After you replace the o-rings oil them up a bit and place the slide cylinder back on. Use teflon tape or blue loctite and re-install the quick disconnect coupler.
I hope this helps answer most questions about remotes as an air system. If not leave a reply and myself or another forum member can answer your question.
