{"id":54,"count":52,"description":"Raymarine offers four types of fishfinders. In the product descriptions of chartplotters with an internal sonar module, you will find the terms S, RV, RVX, RVM and HV. S stands for Single-Channel CHIRP, RV stands for RealVision 3D, and RVM stands for RealVision Max 3D. HV is Hypervision, which has a frequency of up to 1.2 MHz. External modules are also available for RV and RVM sonars, which can be connected to a network where all other Axiom series chartplotters do not have an internal sonar module. The Axiom XL and Axiom2 XL models do not have an integrated sonar module. Fishfinders and sonars are also often simply referred to as echo sounders.","link":"https:\/\/www.navsystems.ee\/en\/product-category\/kalaleidjad\/","name":"Fishfinders","slug":"kaleidoscope","taxonomy":"product_cat","parent":0,"meta":[],"menu_order":25,"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v28.7 (Yoast SEO v28.7) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Real Vision ja Real Vision Max kalaleidjad - NavSystems<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.navsystems.ee\/en\/product-category\/kaleidoscope\/\" \/>\n<meta property=\"og:locale\" content=\"en_GB\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Kalaleidjad Archives\" \/>\n<meta property=\"og:url\" content=\"https:\/\/www.navsystems.ee\/en\/product-category\/kaleidoscope\/\" \/>\n<meta property=\"og:site_name\" content=\"NavSystems\" \/>\n<meta property=\"og:image\" content=\"https:\/\/www.navsystems.ee\/wp-content\/uploads\/2024\/12\/ray.webp\" \/>\n\t<meta property=\"og:image:width\" content=\"500\" \/>\n\t<meta property=\"og:image:height\" content=\"500\" \/>\n\t<meta property=\"og:image:type\" content=\"image\/webp\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\\\/\\\/schema.org\",\"@graph\":[{\"@type\":\"CollectionPage\",\"@id\":\"https:\\\/\\\/www.navsystems.ee\\\/product-category\\\/kalaleidjad\\\/\",\"url\":\"https:\\\/\\\/www.navsystems.ee\\\/product-category\\\/kalaleidjad\\\/\",\"name\":\"Real Vision ja Real Vision Max kalaleidjad - NavSystems\",\"isPartOf\":{\"@id\":\"https:\\\/\\\/www.navsystems.ee\\\/en\\\/#website\"},\"breadcrumb\":{\"@id\":\"https:\\\/\\\/www.navsystems.ee\\\/product-category\\\/kalaleidjad\\\/#breadcrumb\"},\"inLanguage\":\"en-GB\"},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\\\/\\\/www.navsystems.ee\\\/product-category\\\/kalaleidjad\\\/#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Home\",\"item\":\"https:\\\/\\\/www.navsystems.ee\\\/en\\\/\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"Kalaleidjad\"}]},{\"@type\":\"WebSite\",\"@id\":\"https:\\\/\\\/www.navsystems.ee\\\/en\\\/#website\",\"url\":\"https:\\\/\\\/www.navsystems.ee\\\/en\\\/\",\"name\":\"www.navsystems.ee\",\"description\":\"Raymarine kaardiplotter, autopiloot, pinnipiloot, roolipiloot, radar, AIS, VHF, Smart Wind\",\"publisher\":{\"@id\":\"https:\\\/\\\/www.navsystems.ee\\\/en\\\/#organization\"},\"alternateName\":\"Raymarine mereelektroonika\",\"potentialAction\":[{\"@type\":\"SearchAction\",\"target\":{\"@type\":\"EntryPoint\",\"urlTemplate\":\"https:\\\/\\\/www.navsystems.ee\\\/en\\\/?s={search_term_string}\"},\"query-input\":{\"@type\":\"PropertyValueSpecification\",\"valueRequired\":true,\"valueName\":\"search_term_string\"}}],\"inLanguage\":\"en-GB\"},{\"@type\":\"Organization\",\"@id\":\"https:\\\/\\\/www.navsystems.ee\\\/en\\\/#organization\",\"name\":\"NavSystems O\u00dc\",\"alternateName\":\"Raymarine mereelektroonika\",\"url\":\"https:\\\/\\\/www.navsystems.ee\\\/en\\\/\",\"logo\":{\"@type\":\"ImageObject\",\"inLanguage\":\"en-GB\",\"@id\":\"https:\\\/\\\/www.navsystems.ee\\\/en\\\/#\\\/schema\\\/logo\\\/image\\\/\",\"url\":\"https:\\\/\\\/www.navsystems.ee\\\/wp-content\\\/uploads\\\/2026\\\/09\\\/Nav_logo-27092026.webp\",\"contentUrl\":\"https:\\\/\\\/www.navsystems.ee\\\/wp-content\\\/uploads\\\/2026\\\/09\\\/Nav_logo-27092026.webp\",\"width\":620,\"height\":103,\"caption\":\"NavSystems O\u00dc\"},\"image\":{\"@id\":\"https:\\\/\\\/www.navsystems.ee\\\/en\\\/#\\\/schema\\\/logo\\\/image\\\/\"},\"sameAs\":[\"https:\\\/\\\/www.facebook.com\\\/NavSystems\"],\"description\":\"Raymarine esindaja Eestis alates aastast 2004.
