Marking Behavior with Primary Reinforcer

The K-9 BSD's solenoid produces an audible click which serves
as marking stimulus to the animal that the primary reinforcer (reward)
is immediately available, for the preceding behavior. This makes
it very useful to accurately mark active behaviors.

Other benefits include marking behavior when device is not visible
to the animal (such as hidden in blind or some other cover)
and serving as directional training aid for exercises
(such as blind search, send out, or broad jumps).
The device is audible from 400 feet with no background noise, the
same distance as the maximum range of the transmitter and receiver.

Marking Behavior with Secondary Reinforcer
(Verbal Release Command)

The K-9 BSD will produce a very high state of arousal after
training active behaviors in an animal; therefore, making it too
distracting for some types of training or more passive behaviors.
For example, attempting to heel with the device setup in view of
animal will cause crowding and other sign tracking to develop.
Because a large percentage of the animal's focus is on the release
of reward (primary reinforcer), instead of on heeling. As a result, it
is very beneficial to train and use a verbal release command to
mark behavior (such as yes, ok, etc.) at the instant the animal is
performing desired behavior. You can then delay release of reward
by a few seconds and allow the animal time to react to presentation
of reward. This keeps the animal's attention to stay more focused
on heeling. The release command is a bridge, a stimulus that
closes the gap in time between the marker and presentation of
the primary reinforcer, and makes the timing of reward irrelevant.

Marking Behavior with Secondary Reinforcer
(Remote Controlled Release Command)

In other specialized training such as off lead search and odor detection a secondary reinforcer may be trained with use of a beeper collar. This allows use of standard device K-9 BSD-1 to be separated from odor source, while being able to mark correct behavior and then eject reward to the odor source. It also eliminates any possibility of device becoming odor prompt. A second benefit is dog can stay focused on odor alert indication
with out trying to anticipate when and where reward will become available.

Marking Behavior with Verbal NRM
(No Reward Marker)

Use of a no reward marker teaches the animal that its behavior
will not gain a reward. A lot of trainers use “Uh-Uh!” “Nope” or
“Too Bad” as the NRM. The purpose of a NRM is to get the animal
to try something different. It is not a conditioned punisher and should
not be used when animal does something you don’t want
it to ever do. It is used when the animal's behavior might be
correct in different circumstance, but not the one you are teaching.

See an example of NRM being used in the Blind Search Video.
