Active echo fishing lure

A fishing lure comprising:

• an active echo system for interfacing with a boat sonar system, the active echo system including;
• an ultrasound transducer configured to detect a signal from the boat sonar system and transmit an active echo pulse, or a series of active echo pulses, back to the boat sonar system;
• a signal amplifier configured to amplify the signal detected by the ultrasound transducer;
• an analog-to-digital converter configured to digitize the signal from the signal amplifier;
• and
• a microprocessor configured to receive the digitized signal from the analog-to-digital converter and control a pulser circuit, wherein the pulser circuit drives the ultrasound transducer to transmit the active echo pulse, or the series of active echo pulses, back to the boat sonar system.

A fishing lure comprising:

• an active echo system integrated into the fishing lure for interfacing with a boat sonar system, the active echo system including;
• an ultrasound transducer configured to detect a signal from the boat sonar system and subsequently transmit an active echo pulse, or a series of active echo pulses, back to the boat sonar system;
• a signal amplifier configured to amplify the signal detected by the ultrasound transducer and trigger an analog trigger circuit;
• and
• a microprocessor configured to receive the signal from the analog trigger circuit and control a pulser circuit, wherein the pulser circuit drives the ultrasound transducer to transmit the active echo pulse, or the series of active echo pulses, back to the boat sonar system.

An active echo system comprising:

• an ultrasound transducer configured to detect an ultrasound signal and subsequently transmit an ultrasound energy pulse, or a series of ultrasound energy pulses;
• a signal amplifier configured to amplify the ultrasound signal;
• an analog-to-digital converter configured to digitize the ultrasound signal from the signal amplifier;
• and
• a microprocessor configured to receive the ultrasound signal from the analog-to-digital converter and control a pulser circuit, wherein the pulser circuit drives the ultrasound transducer to transmit the ultrasound energy pulse, or the series of ultrasound energy pulses.
