SOS F1-ND

 

Product Description

This is an analog transceiver that has terrific range in the initial search mode and a no frills flux line or grid search operation. It operates on a 457 khz frequency and the pulse rate is 50 p.m.. The F1-ND has a claimed range of up to 90 meters, [though this is in the most ideal conditions].

This transceiver combines a volume dial/range switch with led lights that indicate when the strongest signal has been acheived, and thus when to change the range of the volume switch. The audible "beep" when in search mode is very loud and easily heard.

There is a "forced on" bayonet switch that prevents inadvertantly forgeting to turn the unit on. When the neck/shoulder strap is connected, the unit is turned on in the transmit mode, and the battery check light monitors the system. A large yellow switch is pulled out to the side to switch the unit to search mode. A safety catch is pulled back to allow the search mode switch to operate, this prevents accidental switching to receive mode.
