525
VHF/ADF ADAPTER
Fisherman's radio surveillance lets you know where the "Braggers" are!

Now, you can do more than idly sit by when you hear about somebody else's fishing fortunes; you can actually move in closer to the action! The 525 VHF/ADF 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 plus or minus ten degrees, it's perfect for finding the big fish - or at least the spinners of big fish stories!

• Use with most VHF transceivers. No modification of your radio is required.
• Automatically indicates the relative bearing of any VHF/FM transmitter signal in the ham and marine band covering 121.5 and 130-180 MHz.
• Bright LED indicator on 360-degree azimuth scale shows bearing within one-half second of signal reception.
• Bearing accuracy plus or minus ten degrees.
• Built-in bearing memory holds bearing during incoming transmission.
• Includes 8-element Adcock DF antenna with automatic antenna switch for regular radio use.
• Low power consumption.
• Ideal for power squadrons, rescue units or government safety agencies.
