    thank you so much guys i just purchased my first boat and knew this would be an important option. i have the axiom pro 12 and very excited about this awesome tool. ive spent hours, days studying your vids and really appreciate this valuable information. im hanging up my surfcaster and looking forward to this new journey.

    Nice to mix in the 1 hour tutorials on Thursday night, with a smaller 20 minute version. That was smart on RM. Sometimes 1 hour is to long. Need to keep the audience on there toes. Can add a few Quick 5 minute videos in the mix is a plus as well.
    Hopefully in the very near future RM can add a live or a dedicated video to bird mode. Springtime is coming and thats a perfect time to show this.
    Keep Up The Good Work RM!!!👍👍👍

      Thank you for watching, VS! I'm glad you like the shorter segments. We'll have a nice mix coming for you all year long. The live broadcast will be starting up again in a few weeks. I hope to get Bird Mode in there early on, perhaps while we are at the Miami Boat Show next month. It's a bit too cold right now for humans or birds off the coast of New England!

    Love it! Very very helpful even though I have the Element Series. The one thing I would like to see is the actual HV100 transducer setup on an actual transom from both the back and the side of the HV100.
    Thanks for the video Jim and Tom!!!

      Thank you for watching. I may have some HV100 installation photos I can share. Feel free to email me at james.mcgowan@raymarine.com

    The black space on either side of the white center line on the side view is not actual a blind spot beneath the transducer, it represents the water depth. As the bottom "comes up" (water gets shallower), the black space becomes narrower. Also, there are times the same object appears on both sides demonstrating there is no gap. For example at 2:15 and 13:05. This object is at the nadir or directly beneath the vessel. Since the transducer is directly over the this and other objects at the nadir there is no shadow to assist in discerning object shape.

      Thanks for the clarification and discussion in this point. Many people have a hard time visualizing what is going in with the SideVision Sonar. Let me explain how it is oriented.
      SideVision uses 2 long, bar-shaped ceramics running fore/aft inside the transducer housing. One of them covers the port side of the boat, the other starboard. The sound beam each one generates is 60° wide, but only about 1.4° fore/aft. This give it a wide search area laterally, but a very narrow footprint on the bottom which dramatically increases its resolution. The 2 SideVision beams are tilted downwards from the horizontal about 5° to prevent the introduction of noise at the surface of the water from wave action.
      The DownVision beam is another bar-shaped ceramic running forward and aft, but this time it is oriented to point its single beam straight down. Like the SideVision, it is also 60° wide x 1.4 degrees fore/aft for wide coverage, but high resolution.
      Because of the slight downward tilt of the 2 SideVision beams, each of them overlaps the outer edge of the DownVision beam by about 5° This gives the combined DownVision/SideVision system an overall coverage of about 170° laterally. Starting from 5° below the surface on the port side, then continuously downwards and under the boat, to about 5° below the surface to starboard.
      Without the DownVision in play, there is a gap of about 50-degrees between the port and starboard SideVision beams. That gap gets narrower as the water gets more shallow. Depending on the water depth and the size of the targets, yes, it is possible to see the target in both beams in some circumstances. As the water gets deeper, or the target smaller, this happens less often.
      If you are searching for an object or structure, to be sure you see the entire bottom in high definition, we recommend creating a view that shows both the SideVision and DownVision channels simultaneously.

      @@RaymarineInc Agreed that it can be hard to visualize what the black space represents on SideVision Sonar (traditionally called Side Scan Sonar or SSS). However, it's important to know that the black space isn't really a gap in coverage it is the height of the water column (water depth) between the transducer (boat in this case) and the bottom directly beneath the boat (the nadir). Think of it like a depth sounder turned on it's side hence the "side" in the name. The shape of the acoustic energy beam is like two ping pong paddles one to port and the other starboard. The beam is broad in one direction (between the nadir and looking way out to the side) and narrow in the direction of travel (aft to forward).

    Is there any way to decrease the dual finger scroll screen sensitivity of the Axiom+ when in 3D sonar mode. When I use two fingers to expand / move the 3D image on my Axiom it is VERY sensitive and the image expands exponentialy.

    • @RaymarineInc
      @RaymarineInc  3 месяца назад

      At the moment there is not a way to change the touch sensitivity, but I'll make the request to our product team.

    Do you have plans to develop a forward looking sonar at some point ?

    • @RaymarineInc
      @RaymarineInc  2 года назад

      I can't speak about unreleased or in-development products. We know there is interest in this technology, and we do have a very talented sonar team looking at things. Hopefully we'll have more news to share soon.

    Hi can you give me some ideas as to why i can't scan to port unless I'm drifting or just clicked in gear
    cheers Dave

    • @RaymarineInc

      Our SideVision sonar works best when the boat is moving at slow speed. When the boat is stationary, the side-scan sonar is painting the same area over and over again. If a fish or some other object enters the beam you'll see it, but it won't necessarily have as much definition. When moving, the very narrow slices created by each ping of the sonar are stitched together into an image.
      As for not seeing to port, it may be that the lower unit of your motor is just slightly in the beam of the transducer. When moving, the sonar's automatically adjusted tune parameters change just slightly so it then tunes out the nearby echo of that fixed object.
