与上水最好的 Garmin 地图升级
Fish with the Power of CHIRP
5-inch color display with keypad control
Includes GT22-TM transducer with high wide CHIRP, 250 W and Garmin CHIRP DownV&, 350 W transducer
Preloaded LakeV& HD maps cover 17,000 total lakes, of which 13,000 are HD lakes with 1-foot contours shore to shore
Includes Quickdraw Contours custom HD map creation software
Internal 5 Hz GPS updates position and heading 5 times per second
It’s time you started fishing with the power of CHIRP sonar. The easy-to-install, easy-to-use 5-inch echoMAP CHIRP 53dv includes transducer for high wide CHIRP sonar and Garmin CHIRP DownV&, the clearest scanning sonar on the water. It includes Quickdraw Contours software to instantly create your very own HD maps with 1-foot contours as you fish. Internal 5 Hz GPS updates position and heading 5 times per second. It even supports NMEA 2000 for engine data, sensors, autopilots and more. Cords plug directly into the mount, allowing you to quickly install and remove your device from power and mount. Transom and trolling motor mounts included.
The Garmin CHIRP Difference
The built-in sonar capabilities of echoMAP 53dv include&CHIRP sonar, the most sophisticated sonar technology available for the fishing and boating public. CHIRP sonar provides amazingly clear target separation and definition because it puts even more energy onto the target than traditional sonar. It also includes sonar-recording capability that coordinates the timing of the sonar return with your boat's position and saves digital information for playback on a computer using&HomePort planning software. Use the user data sharing cable to share waypoints and routes between multiple devices.
Clearest Scanning Sonar on the Water
Garmin DownV& scanning sonar gives you a nearly photographic image down to 750 feet below your boat. You clearly see structure, submerged objects and fish. Traditional Garmin HD-ID sonar and DownV& scanning sonar are combined into 1 transducer. Also provides HD-ID support for Minn Kota and MotorGuide trolling motors with integrated transducers.
Preloaded LakeV& HD Maps
These highly detailed freshwater maps include 17,000+ U.S. lakes, rivers and reservoirs (more than double the number of preloaded lakes of any competitor). That number also includes more than 13,000 HD lakes with 1-foot contours shoreline to shoreline (again, 2 times more than our competition). LakeV& HD gives you excellent detail of underwater features, plus Shallow Water Shading allows you to designate a minimum depth. It also shows interstates, highways, general roads and bridges, designated fishing areas, docks, boat ramps, marinas and campgrounds.
Create Your Own HD Maps
Quickdraw Contours is a free, easy-to-use software feature already installed on your echoMAP CHIRP 53dv. It instantly creates your own personalized HD fishing maps on screen with 1-foot contours. Tailo you own them. Keep the data for yourself, or share it with Garmin or your friends. No special surveying expertise is required. You just fish while Quickdraw Contours creates maps. There’s no waiting around or sending your files away like other mapping software requires — your results appear instantly. Use with any Garmin Panoptix transducer, any HD-ID sonar, any CHIRP-enabled, Garmin DownV& transducer or NMEA 2000-compatible depth transducer. Have more than 1 sonar device installed onboard? Quickdraw Contours automatically selects the most capable sonar device to provide the very best results for you.
Heading and Position Refreshed 5 Times per Second
Fast, responsive 5 Hz GPS/GLONASS refreshes your position and heading 5 times each second to make your movement on the screen more fluid. Now it’s quick and easy to drop up to 5,000 accurate waypoints and find your way back to your secret fishing hot spots.
Take Your echoMAP with You
When you’re off the water, it’s easy to keep your echoMAP safe and secure. You don’t have to mess with plugging and unplugging wires from the unit because the cords plug directly into the mount. This allows you to quickly install and remove your echoMAP from power and the mount.
Upgrade with the Best Garmin Maps on the Water
A single microSD card slot provides expandable memory for accessory map purchases such as&LakeV& HD Ultra,&BlueChart g2&or&BlueChart g2 Vision. LakeV& HD Ultra adds high-resolution relief shading, Dynamic Lake Level, Depth Range Shading and more than 92 MaxDef lakes.&LakeV& HD Ultra and BlueChart g2 Vision also provide exclusive Garmin Auto Guidance, a technology that directs you to your hot spots. Based on your boat’s specifications, Auto Guidance instantly creates a visual path you can follow to avoid shallow water and other charted obstructions.
Enhanced Auto Guidance
Just enter the location where you want to go and patented Garmin Auto Guidance technology instantly searches through relevant charts to create a safe, virtual pathway on the display that helps you avoid low bridges, shallow water and other charted obstructions en route.
With enhanced Version 2.0, you have access to more features and capabilities. You’re able to adjust the calculated Auto Guidance pathway by inserting “via” points at interim stops or landmarks along your desired route. You can easily review hazard points along your calculated path. And you can even engage your compatible Garmin autopilot to follow the Auto Guidance route, automatically. Other 2.0 enhancements give you the ability to calculate arrival times at any point on your route (great for timing arrivals to correspond with bridge openings and other time-critical events). Better still, you can now save your plotted Auto Guidance paths for future navigation by backing them up on an SD card with your BlueChart&g2 Vision or LakeV& HD Ultra cartography.
GPX Waypoints Transfer
If you have waypoints, tracks or frequently used routes stored on another manufacturer’s GPS product - or on a Garmin handheld device - now it’s easier than ever to transfer those items to your new Garmin chartplotter, via industry-standard GPX software formatting. GPX is an open standard format for GPS data exchange across platforms and applications. With this easy-to-use interface technology, Garmin has taken “no waypoint left behind” to a whole new level of trade-up convenience.
BlueChart g2 Vision or LakeV& HD Ultra SD card is required for this technology.

River Flows In You
问题四:我的7dv是什么型号探头?定频探头和调频探头有什么区别?哪个好?我应该用什么频率钓鱼?我们常用的7dv,标配的探头是GT20。当然,7dv可以配置的探头型号很多,每一种不同的探头,都有各自不同的特点。同样一个7dv的主机,配置不同的探头,就能实现不同场合的用途。我们先来了解一下常用的频率。蓝水型普通鱼探仪最常用的工作频率一般设计为50kHz和200kHz;淡水型普通鱼探仪最常用的工作频率一般设计为77kHz和200kHz。 对于不同的频率,其传播距离和信号清晰度各有不同。一般情况下,频率越高则波长越短,信号越清晰,但是传播距离越短;频率越低则波长越长,传播距离远但是信号会模糊。一般情况下,200kHz的探测鱼群回波最清晰,但是通常的测深范围不超过600ft/200m,而且通常波束角设计为20°以内,适用于浅层水域,主要用于显示精细目标画面。 50kHz的探测鱼群回波可以看得比较深,另外波束角也设计的比较大,通常可达到40°以上,主要用于显示深层水底轮廓地形。由于波长较长,很容易忽略掉一些细小目标。 77kHz的探测鱼群可以看得相对深一些,但是一般侧重于淡水湖使用,特别增加波束角达到30°以上。海水鱼与淡水鱼等不同鱼种对不同频率的回波响应有所不同,但是普遍对200kHz的频率均有比较明显的反应,这也是为什么200kHz是鱼探仪的主要工作频率。 我们再来了解一下传统声纳和调频声纳的区别传统声纳是基于发射一个或两个不同频率的超声波脉冲,通过衡量声波发射与在水中受到鱼群或其它目标的阻碍反射产生回波的时间间隔,确定鱼群或目标所在的深度;测量接收获得的回波振幅结构与强度来进行数据分析与处理,进而判断水下目标的大小、分布与数量等。总体来讲靠单个频率的脉冲所能获得的数据信息量是十分有限,而且超声波脉冲要穿越水层抵达目标需要一定的间隔,而脉冲长了也会将水下多个目标混淆。许多号称数字高清的鱼探声纳技术,大多数也只是在软件分析处理和显示液晶屏幕像素方面作改进,而对原始数据源方面并没有什么变化。传统声纳的效果就可以理解为类似调幅AM收音机。CHIRP调频声纳技术是利用扩展频谱脉冲压缩技术,通过发射一组一组延长了的并具有更好水下穿透能力的从低到高连续频率的合成压缩脉冲对水下鱼群和目标进行探测。通过DSP数字处理单元对包含有各种频率成分的合成回波之时间和强度进行分析处理,从而获得更加高清分辨率的鱼群或目标图像。一般CHIRP调频声纳根据工作深度和使用要求不同,一般分为三个工作频段:【低频段】28-65kHz 最深可达3048米【中频段】85-135kHz 最深可达1981米【高频段】130-210kHz 最深可达1005米由于CHIRP调频声纳使用了比较宽的系列频率,也就可以使得鱼探仪的声纳处理单元可以根据更加丰富的原始数据源处理获得更加准确与清晰的鱼群目标和水下地形结构的图像。CHIRP调频声纳的最大特点就是鱼群目标清晰、目标之间的分离度高、画面简洁一目了然。CHIRP调频声纳的效果就可以理解为类似调频FM收音机。好了,我们再来了解一下能够匹配佳明7dv的几款常用探头的功能区别。GT20。传统声纳是定频77/200khz,下扫成像是CHIRP455/800khz。适合淡水。具体参数如下:GT8HW。高频CHIRP探头,频率150--240khz。没有下扫成像。直接悬挂,非尾挂。没有温度传感器。适合冰钓和淡水筏钓。遗憾的是7dv的下扫选项失去了作用。GT21。传统频率50/200KHZ。下扫成像是CHIRP455/800khz。50khz探测深度更深,适合蓝水。当然,200khz在淡水也可以应用。GT22。完全CHIRP探头。既有传统选项也有下扫选项。传统为高频CHIRP150--240KHZ,下扫成像为CHIRP455/800KHZ。适合淡水。GT23。完全CHIRP探头。既有传统选项也有下扫选项。传统为中频CHIRP80--160KHZ,探测深度比较深。下扫成像是CHIRP455/800KHZ。蓝水淡水均适合。最后,我们来看看几款探头实际效果的差别。很显然,CHIRP探头图像更清晰,分辨率更高。陆续还会推出一些续篇,谢谢收看。如有疑问,请联络微信ZCD共同讨论。
