Here's a new ''surveillance'' device that can help you pinpoint the location of fishing ''braggarts'' and move in closer to the action. The 525 VHF adapter is a computer-controlled VHF direction finder that works with your existing VHF radio to pinpoint the direction of radio signal sources. With a bearing accuracy of 10, it's perfect for finding the big fish, or at least the fish story tellers! The 525 automatically indicates the relative bearing of any VHF/FM transmitter signal in the ham and marine band from 130-180 MHz. Includes an 8-element Adcock DF antenna with automatic antenna switch, which fits on an antenna extension or 1 1/4'' tubing.

• Attach it to almost any VHF radio
• No modification is required to form an integral ADF/radiotelephone unit
• 360 azimuth scale shows bearing within 0.5 sec. of signal reception
• Bright LED indicator
• Direction finding on coastal transmitting stations
• Includes 33' antenna cable
• Low power consumption of 2.4W @ 12v DC
• Measures 8.7''W x 5.2''H x 2.7''D
• Antenna measures 15 1/2''W x 35''H x 15 1/2''D
