new bit of kit for camcorder

Wireless remote control

You would not believe how hard it was to find this bit of kit at a reasonable price. Sony prices are sky high if you can find one made by them. it was on youtube I spotted a demo of it.
sourcing one in the UK ???? this was the last this company had from whom I got it. the range is supposed to be about 100ft but not tried it yet at tghat distance
what it does is switch the camcorder on/off- zoom in/out and display a grid if wanted.
