Why Master Sonar?

The morning was quite cool, conditions not necessarily perfect for barra. Through the aid of a simple process the chances of catching one were increased by applying a collection of skills through linked formation.

Accurately casting a lure, allowing it to sink to the appropriate depth, then fishing it steadily past the nose of a metre-long fish. Straight forward, really.


….but those skills pivot off ‘mastering sonar’, identifying the exact position of the barra relative to the transducer to less than 50 cm, identifying their depth to less than 20 cm, then working backwards from there to position the boat, selecting the perfect lure weight, to then cast on a dime (allowing for minimal or no error margin – 10cm ?!?!?) and factoring in tide flow shift as the lure sinks. Accuracy with lure presentation for barra is critical, especially on days they aren’t so hungry.

Mastering sonar is a trade skill; you see fish off to the starboard side of the vessel when on a 60 ft range, but how far are they from the transducer? If they’re 47 feet away, they’re 47 feet away. Now what?

How far is 47 feet? (In metres, it’s approximately 14.1) If given the chance- stand in the backyard and take a guess how far 47 feet or 14.1 metres is from your toes. Mark it, then measure it.

Over 80% percent of anglers will get this wrong- so what does that mean? It also means chances are high that many anglers will struggle to guess depth in distance. All of a sudden accuracy goes out the window- a bit like shooting a gun blindfolded!

If we give sonar technology the time it deserves plus the extra brain effort required to link sonar information with angler action the catch efficiency improves dramatically. Sonar screens share incredible amounts of usable information, and quite a lot is overlooked, and therefore the advantage is lost. You need to process every snippet of free information rolling onto that screen to help make decisions on ‘what to do next!’

The majority of these king threadfin are swimming within a three foot target zone (90cm). That target zone is between 15ft and 18ft below the surface (4.5m- 5.4m) Is your lure even close to the target zone? If not you may need to give sonar information a second thought.

The sonar course is instrumental in helping anglers master this element of the fishing game. Not only does it open the mind and train the eyes to see but it value adds through explaining further content linked to fishing- the type that simply puts more fish on deck. Sharp sonar skills allow you to target individual fish, rather than casting and hoping.

Even experienced anglers are learning volumes of content from this course. Once the eyes are open, you won’t miss tricky schools of fish again, instead they will be noticed and a whole strategy applied based on the info extracted from the screen. Interpreting images accurately sets and angler up to finish off the deal. If a bullet misses a target by 30 cm it’s a miss, shooters make adjustments to score a direct hit. Anglers need to master sonar before the rest of the story can unfold. So much hinges off sonar skills…………… master it, personal growth is exciting!


“Mate you have done a fantastic job, I absolutely love it. Your sonar training is incredible, am learning heaps and have to go back to watch all of them and recap on the ones I’ve watched. When you think you understand sonars, you don’t realise some of simple but important things we get wrong.”

“Each individual module was thorough and despite only watching it once so far I have gained a massive amount of knowledge. After looking at your interpretation of the imaging, I realise how much more information can be gleaned from the sounder that I never considered before. I love your work!”

“Hey mate,
The sonar course is amazing. Well done. That is the best value online course, so much detail and specific info. Blew me away.”
