I make the Pro Release with a 3 foot leash, because it's a good length for most people's application. You might want to cut it off and make a custom length for your application. Tall boats might work better with 6 feet and Kayaks might work best with 18 inches. I would be happy to build you what you need.

There are a couple ways to load your braid or mono-filament mainline onto the Pro Release.

1. You can wrap the bobbin and get all the benefits of it's unique design. When wrapping around the bobbin, It is important to load the fishing line correctly. With thumbnut pointing down, open the bobbin, lay the line on the "inside" of the bobbin, and proceed to wrap 3 times around without crossing. When the bobbin closes, the line from the rod tip should be enclosed in the cavity behind the bobbin. The line to the hook should exit from beneath the bobbin. The bobbin should close securely, and the wraps should be held by the rubber wheel to prevent slipping when putting a bend in the rod. See pictures and videos.

Incorrectly wrapping from behind the bobbin will allow the device to roll over when you deploy it, causing a twist in front of the bobbin.

Bait checks/manual release:
The Pro Release is designed to release smoothly from a pull on the end of the line. Care should be taken to manually release it from above. If it's not set too tight, you will be able to lift the rod moderately until the bobbin opens and the line comes off.  If the line doesn't release immediately from the bobbin, reduce tension to let the gear or fish pull the wraps off the bulb of the bobbin. Proper tension adjustment and minimal wraps improves manual release.

Don't spin up your line:
If using rotating gear, make sure to use good swivels on your line! Over the last couple years, 360 flashers and inline rotating flashers have become very popular for trolling. If twists are traveling up your line due to a bad swivel or fouled swivel, it may spin everything up. Use several bead chains and plastic hoods over the swivels when fishing in grass, jellyfish, moss, etc. If you are having trouble with everything spinning up, fix your swivel or just load release with a loop like other releases.

Also, because the Pro Release can be set to release at extreme pressures, it is possible to have it set way too tight so the fish and/or you aren't able to release it. You want to have it set just tight enough so that it doesn't false release, but does release on a bite. You don't want it so tight that the bobbin can't open with the rod you are using or the fish you are targeting.
 

2. You can spin a loop like with other releases. Many of my expert Kokanee customers prefer this method, because it's quick, it's what they are used to, it works perfect, and you don't have to worry about wrapping the bobbin.

Sorry, not much of a video editor yet. First 1:28 I got out of the channel and my starboard rod was dragging bottom.
