Phoenix Bass Fishing League – Forward-Facing Sonar FAQ

For 2025, a suite of new forward-facing sonar rules will go into effect across MLF’s tournament circuits. Here are some of the frequently asked questions specific to the Phoenix Bass Fishing League.

What is the forward-facing sonar rule change for the 2025 Phoenix Bass Fishing League?  

All tournament boats are limited to the use of two forward-facing or 360-degree sonar transducers in any combination. Forward-facing transducers are defined as any transducers that provide live (real-time) images. Three hundred- and sixty-degree (360) transducers are defined as any transducers that produce a beam that rotates 360 degrees. 

• Phoenix Bass Fishing League anglers are allowed to use up to two forward-facing or 360-degree sonar transducers during all days of competition. 

• Any Phoenix Bass Fishing League anglers who have more than two forward-facing and 360-degree sonar transducers must disconnect the additional transducers, and the cable plugs must be covered and locked with a free, high-visibility lock box provided by MLF throughout the ENTIRETY OF COMPETITION.

Why is this rule change being implemented?

To allow tournament anglers to utilize the fish-catching power of forward-facing and 360-degree sonar technology while preserving traditional fishing techniques enjoyed by millions of anglers and fans.  

When does the new rule go into effect? 

Jan. 1, 2025. 

Are there any exceptions to the two-transducer rule for specific tournaments or circumstances?

The two-transducer rule applies universally to all Phoenix Bass Fishing League events. Exceptions are not permitted, as the rule is designed to maintain consistency and fairness across all competitions.

What is the lock box, and how does it work?

The lock box is a device designed and engineered by Precision Sonar to enforce MLF’s new forward-facing sonar rules. It disables the use of transducers once disconnected by locking and securing the cable plugs with a high-visibility lock box. This ensures compliance with the rule while maintaining fairness during tournaments.

Who is required to use the lock box during Phoenix Bass Fishing League tournaments?

Any Phoenix Bass Fishing League competitor who has more than two forward-facing and/or 360-degree sonar transducers installed on their boat is required to use the lock box during competition to disable the excess transducers. 

Will the use of the lock box affect the performance or settings of my remaining transducers?

No, the lock box only disables the usage of excess transducers and does not interfere with the functionality or settings of the two transducers you are permitted to use during the tournament. The lock box comes with heavy duty straps to secure safely to electronics mounts.

How does it impact anglers and Phoenix Bass Fishing League events?

Phoenix Bass Fishing League anglers will be allowed to use up to two forward-facing sonar and 360-degree sonar transducers during all days of competition. 

Anglers will be required to: 

• Disclose their setup and need for the device to the tournament director at or immediately following the pre-tournament meeting.
• Follow Tournament Director’s pre-tournament instructions to obtain a lock box from MLF staff prior to the tournament and install the device prior to boat launch – a quick and straightforward process that ensures excess transducers are disconnected and cable plugs are securely capped with a high-visibility lock box.
• Make a quick stop by the Precision Sonar Lock Station after use at the end of the event to have the device unlocked and returned to MLF staff.

How do I disclose my setup and obtain the lock box from the tournament director?

Before the start of the tournament, competitors must inform the tournament director if their boat is equipped with more than two forward-facing and/or 360-degree transducers.

The Tournament Director will provide instructions on when/where to obtain the lock box prior to Day 1 for all competitors, along with instructions for installation.

Where do we get the lock box? 

Phoenix Bass Fishing League anglers will be able to obtain a lock box during event registration or the morning of the event at the MLF Tournament Trailer prior to launch. The device is self-locking, and anglers are responsible for installing the lock box PRIOR to going through boat check at each tournament.  

What is the installation process for the lock box, and how long does it take?

Installing the lock box is a quick and simple process. Competitors will disconnect the excess transducers and secure the cable plugs using the self-locking lock box provided. The installation typically takes just a few seconds and can be easily completed before the tournament begins and prior to going through boat check.

How do I have the lock box removed after competition ends? 

Anglers must stop at the Precision Sonar Lock Station following check-in to have their lock box quickly removed by an MLF official.

Where will the Precision Sonar Lock Station be located?

The Precision Sonar Lock Stations will be located at the launch ramp for each event. The Tournament Director will relay specific information regarding any changes to the exact location of the Precision Sonar Lock Station to competitors prior to the tournament. If anglers launch at a different ramp, they must stop at the Precision Sonar Lock Station to have their lock box removed prior to heading to the alternate ramp to load their boat. 

How will the rule be enforced?

During boat check, MLF staff will be visually checking for the high-visibility lock box on any boats with more than two forward-facing or 360-degree sonar transducers.

MLF emphasizes the importance of integrity in competition, holding anglers to a self-imposed standard of fairness and sportsmanship, including adherence to the newly established forward-facing sonar rules, which will be monitored and enforced collectively by the fishing community. 

What happens if I fail to comply with the new sonar rule or the use of the lock box?

Non-compliance with the new forward-facing sonar rule or failure to use the lock box as required may result in penalties, disqualification, or other disciplinary actions as determined by the Tournament Director. Competitors are encouraged to follow the rules closely to ensure fair competition.

What do I do if I forget to have my lock box removed after the event? 

Contact your Tournament Director. 

Can I use the lock box for other purposes outside of MLF tournaments? 

The lock box is designed for MLF tournament compliance and will not be sold or used for any other purposes. 

What should I do if I experience technical issues with the lock box during an event?

If you encounter any technical issues with the lock box, immediately notify the Tournament Director. They will assist in resolving the issue to ensure you remain compliant with the rules.

Who do I contact for questions about the lock box?

Phoenix Bass Fishing League anglers should contact their Tournament Director, for any additional questions regarding the lock box.
