I've owned the ShutterBeam, the Time Machine, and, most recently, the Phototrap (from Bill Forbes). The Time Machine is probably the most versatile, but I really like the ease of set-up of the PhotoTrap. See the following link for a discussion of the Phototrap, with some comparison to the ShutterBeam and Time Machine. http://www.naturescapes.net/phpBB3/v...otrap#p1383575
Joseph, Your knowledge and feedback about Byran is much appreciated.
Ed, Your links have opened up a lot of information that will help me decide which system to adopt. Thanks for taking the time. I'd be interested to know how you got on with the narrower beams in Direct mode using PhotoTrap as that seems to be a weak area of that product.
