RCU Forums - Frequency scanner?

A few weeks ago at the Winimac jet fly a fellow there had an R/C frequency Scanner specifically developed for R/C use. This was a white unit with what looked like a 3 or 4 Sq. In. LCD display. This scanner had the ability to scan up and down the R/C range and it could also lock onto a channel and tell how strong the signal strength was in db.

Anybody know what brand this was and where I get one? A website would be nice.

BTW, this is not the Icom R1 or R10, although I have also been considering getting one of these as well.

Thanks,
Randy
