It is a pity, that Wisycom has not the fame as the ohter brands.
I am using them now for 4 years. First the MCR 52 with the old transmitters and now the MCR54 with the new ones.
During this time I maybe had a handful of drop outs.
IN the beginning I scanned everytime I came to a new place. Since I have the MCR54 I often totally forgot to scan, because they are working rock solid.
For bag work I use the Lectro dipols and on the cart the Wisycom sharks. On both antennas the range ist crazy. No problems through thick walls, cars and other stuff. Sometimes I even cant see the actors but still receiving them. Battery Life is long. I change them normaly just after lunch. I found the right gain and I only have to turn it down when it gets really lound.
This is my nearly set and forget wireless system.
Peace.
