Garmin quickdraw sonars5/9/2024 Garmin’s Quickdraw mapping (a feature available on compatible fishfinders) is incredibly useful, especially when fishing on uncharted bodies of water. It is also helpful to be able to mark waypoints on productive areas so you can easily find these locations once again in the future.įor more detailed and up-to-date mapping data, there are SD, MicroSD, and downloadable subscription-based maps available for compatible fishfinder models through Garmin and Navionics. Maps can help with revealing key areas, such as: points, contours, humps, and other likely structure. Some sonar models have built-in GPS capabilities and basic mapping. If you’re considering a fishfinder for year-round use, you can learn more about all fishfinder technologies. SAIL carries Garmin ice fishing sonar bundles which, with the necessary accessories, can also be mounted on a boat or other watercraft. Having the history is great as you are able to scroll back through to further inspect how a fish reacted, or see what depth they came in at. ![]() It provides a “history” of the water column since it keeps scrolling and updating constantly rather than a flasher which only shows the current view. ![]() One of the most popular views for traditional 2D and CHIRP is the traditional 2D scrolling view. Unlike traditional 2D sonar which uses either a single or dual frequency, CHIRP transducers send a continuous sweep using multiple frequencies to provide an even clearer, high resolution image which improves detail, even in deeper waters. They can also automatically make adjustments to certain settings in order to be as user-friendly as possible and to provide the clearest return (for example: using Auto Depth and Auto Gain features).ĬHIRP is the latest in 2D sonar technology and it is available in some Garmin fishfinder models. All of these views can either be displayed as a single full-screen view or as part of a split-screen view along with 2 or more different visualizations.ĭigital sonars also offer far more advanced settings and customization options such as different colour palettes, ping speeds, brightness settings and more. Popular visualization options include: traditional 2D scrolling, a-scope, flasher emulator, zoom window, etc. Digital sonar units also typically feature an LCD display, which allows for the sonar return to be displayed using a myriad of different views. Unlike with an analogue flasher unit, the sonar return is first digitized and processed by the unit before then being displayed on screen which allows for more detail/information to be extracted from the sonar return. Ice Fishing Sonar : Digital (Traditional 2D and CHIRP)ĭigital sonar units provide a similar view of what’s in the water column immediately below your feet, but does so while offering far more detail and functionality compared to analogue flashers.

As a very general rule, wider beam angles are typically better suited for shallower water whereas narrower beam angles are better in deeper waters. ![]() Dual beam transducers allow anglers to select between either a narrow or wide beam. Flashers typically come equipped with either single or dual beam transducers. User adjustable settings on most flasher models are typically limited to gain (adjusts the sensitivity of the sonar), depth range (sets the max depth range of the circular display), zoom (allows users to zoom in on a section of the water column), beam angle (select between wide or narrow beam angle) and interference rejection (helps to mitigate interference from other nearby units). Flashers provide a simplified real-time view of what is going on in the water column directly below your feet. Analogue flashers (also referred to as mechanical flashers) are a type of sonar that displays signal returns from objects within its beam, including fish, structure and bottom, as lighted coloured bars on a static circular display.
