I had a "failsafe." I played with Wal-Mart subs and installed a telescoping antenna on the transmitter. I kept the antenna collapsed as I ranged the sub outward; when I noticed the boat wasn't responding as well as when underfoot, I made a mental note not to go further--and extended the antenna to rein the sub back into its prime range.
