The club I belong to has both styles, the wireless are handier but the corded have been more reliable and the pullers can control them a little easier. Have a couple members that have their own ERADs & we tried them at 1 registered shoot, they worked fine but it was a hassle keeping track of them. so we have stayed with the corded sets. Just our experience.--Ross Puls
I can attest to the solid performer issue. We just finished a 4 day Florida chain shoot. We threw about 40,000 targets and not one glitch with the CVR wireless. Over the years we bought 4 corded and 2 wireless CVR systems from Bob Schultz, absolutely the best to deal with as are his staff.
Do not use rechargable batteries! Each mic pod had a "low Battery" light on it reminding its time to start thinking about changing batteries. Rechargable give no warning, the just go from working to not working.
