Are all thru hull transducers the same size?
Are all thru hull transducers the same size?
Size isn’t dictated by anything particular. Airmar makes several 1″ and 2″ thru-hulls that all do the same things for virtually every manufacturer of electronics. If you want temp, depth, speed and power, there are TD’s shafted in both sizes. It’s just all about how much you want to spend.
Where is the proper placement of transducer?
Transducer placement should be aft and close to the centerline. It needs to be located low enough that the transducer is in the water at all times. Consider items such as the lifting strap placement into the location as well as trailer bunks and rollers if it is a trailered vessel.
Can I mount my transducer inside the hull?
Most marine-electronics brands offer an inside-the-hull transducer kit that can be fastened to the hull’s interior. This will work only with solid fiberglass hulls (excluding balsa core or laminated hull construction that might contain air pockets). Expect some signal loss.
What is the difference between 50 kHz and 200 kHz?
200 khz means that the transducer is putting out 200,000 pulses per second. A 50 khz frequency is putting out 50,000 pulses per second. The higher the khz number, the higher the frequency, but the lower the cone angle that is required to produce the higher frequency.
What is the difference between 83 kHz and 200 kHz?
200 kHz has a narrower cone than does 83 kHz. With a 60 degree cone, the 83 kHz is used for downrigger applications. It can be used to mark the cannonballs that would be outside of the narrower, 200 kHz cone. Sptitz, the most common application is to run both frequencies at the same time.
How far below the boat should a transducer be?
Thirdly the best bet when mounting your transducer to read at speed is to have the bottom of it 3-4 mm below the waterline. Because the transducer can only ping in water so you do want it submerged. If it’s too deep sometimes the front face of it will create turbulence and bubbles = bad.
Where should I mount the transducer on a boat?
The general rule of thumb is to mount the transducer to the starboard side, which is the down stroke of most single outboard boat propellers (right hand lower unit). This side produces the least amount of turbulence and is most efficient in delivering the best performance.
Can a transducer read through fiberglass hull?
The standard (83/200 kHz) pod style transducer and standard (83/200 kHz) skimmer transducer, have a proven track record of performing well shooting through a fiberglass hull when installed correctly. You will lose 10-15% of sonar performance when shooting through fiberglass.
