Press  +  to  increase  sensitivity.  Press  - 

to  decrease.  A  single  touch  and  release 

adjusts  the  level  in  a  small  increment. 

Continuous  pressing  results  in  a  continu-

ous adjustment.

Threshold

Press  the  MENU  touch  pad  to  display 

THRESH  on  the  screen  (above,  with  fac-

tory  setting  indicated  on  Upper  Scale), 

and you can use the + and - touch pads to 

adjust the threshold of sound that is being 

produced  by  the  GTI  1500  as  it  scans. 

Multiple touches will increase or decrease 

the sound level. Changes can be seen on 

the Upper Scale.

You  can  search  silently  or  at  any  level  of 

constant sound. Charles Garrett and veter-

an hobbyists usually prefer to operate the 

instrument at a minimum level of audible 

sound but this is no longer necessary.
