I had problems with FP seeing the remote with bifocals. Been running an Icotec Nightstalker+ for almost 2yrs now and can use its remote w/o my glasses.Work on hand calling sounds mainly to learn new sounds I don’t already use. My foxpro gave up the ghost this last season and I’ll just switch to all hand calls. My old eyes can’t see the remote screen well enough to use much anymore. Target practice once a month if not more often might be something I will do. Have a safe and happy summer.
