that are below the discrimination threshold. This can help in tar-

get separation, especially in trashy areas, and can also help in

pinpointing targets. On the other hand, the increased target

responses can be overwhelming and create audio fatigue, espe-

cially for new users.

Mixed mode equally applies both the all-metal audio and

the discrimination audio to the speaker or headphones. In the

absence of targets, or for targets below the discrimination

threshold, the mixed-mode audio output will be the all-metal

response, and you will hear the all-metal threshold plus the all-

metal response of rejected targets. When an accepted target is

detected, the discrimination audio will take over and you will

hear the discrimination tone for the target; for a rejected target

you will still get an audio null. Due to a hardware limitation,

both audios cannot sound at the exact same time, so as the dis-

crimination audio comes in, the all-metal audio cuts out. This is

illustrated below.

When mixed-mode is selected, there are no additional set-

tings. By default, Tone ID is on, modulation is set to 1, and all-

metal VCO is on.
