Once the focus is set switch the lens to manual focus and use gaffer tape on the camera barrel ensuring the focus ring won't move. I also tape down my pocket wizard cable so it doesn't come out of the camera. Turn on the remote and set your channel. If anyone else is using a remote make sure you aren't using the same channels. Match the channel on your second remote and test. Once everything is ready to go (it should really only take you 5-10 minutes to setup once you have done it the first time) return the ladder.
IMPORTANT: Remote cameras should ALWAYS be a secondary shot. Your handheld camera is your primary shot and what you should rely on. You won't know what you got on your remote camera until after the game once you take down your rig and if it ended up not working correctly then you will be left with nothing.
IMPORTANT #2: Know that in most cases you won't be able to get to your camera until after the game is over so if you are on a deadline know that the remote photos may be some of the last things you turn in.
IMPORTANT #3: Throughout the game continually check your remote to make sure you didn't accidentally change your channel. It happens especially if you use more than one camera on the floor. You don't want to realize you bumped it early in the game and didn't get anything from your remote because your channel was changed. Trust me you will be really upset at the end of the game if this happens.
Last but not least don't get frustrated if it doesn't work the way you had hoped the first attempt. If you follow my photos you see my best shots not the thousands of shots that didn't work out. I have tried various remotes that never worked out but I learned something with each one that I was able to use for future events. Also know that your remote camera may only yield 3-5 keepers per game if everything goes right. Most importantly have fun and don't be afraid to try something new and different. If you are able to do remotes and get good at them it will take your sports photography to a completely different level.
