When a boat is "on plane" (meaning it's moving fast enough to glide on the water's surface), depth sounders often lose their ability to read the water depth accurately. This is because the transducer, which sends out sonar pulses to measure depth, is no longer submerged and contacting the water properly.Here's why and what you can do:Why Depth Readings Fail on Plane:

  • Transducer Position:When a boat is on plane, the hull lifts out of the water, and the transducer attached to the hull is no longer fully submerged. 
  • Air Interference:Air, being a much weaker medium than water, interferes with the sonar signals, making it difficult to get accurate depth readings. 
  • Speed and Turbulence:The rapid movement of the boat and the water disturbance can also disrupt the transducer's ability to send and receive clear sonar signals. 

Helpful hints for Accurate Depth Readings on Plane:

  • High-Speed Sonar:Some fish finders or depth sounders have "high-speed" sonar modes designed to minimize the effects of turbulence and air interference. 
  • Proper Transducer Placement:Ensure the transducer is properly mounted and facing the correct direction to maximize its ability to receive clear sonar signals. 
  • Device Settings:Some fish finders have settings that allow you to adjust the sensitivity and gain of the sonar, which can help optimize the readings at different speeds.

There are several reasons a transducer might lose a depth reading when travelling at high speeds. It could be related to the transducer's mounting location, device settings, or the vessel could be outrunning the return signal if it is moving too fast.

See-Right

Standard brackets only have 2 adjustments up and down and angle to hull

Q1. Is your transducer in it's best position ( How do you know )

Q2. How many times have you redrilled trying to find that best position

Q3. Are you happy with your transducer position, would you like to adjust your transducer and find a better position without drilling more holes in your hull.

Answer. The See-Right-Marine transducer bracket gives you the ability to set your transducer in 4 directions to give you the best position possible, up and down, side to side, angle to hull and rotation. Without having to remount the bracket.

Universal Transducer Bracket

The See-Right Universal has been designed to take any transducer using the plastic or stainless mount bracket suppied with your transducer, the bracket is a precision, four-way adjustable transducer mounting system designed to fine-tune your transducer’s position — without needing to remount or redrill holes in your hull. It gives you the flexibility to adjustup/down,side-to-side,angle relative to the hull, androtational alignment.  It is marketed as a “universal unit for all transducers,” with specialized versions for Humminbird, Lowrance, or Garmin planned.See-Right-Marine
