Choosing the Best Garmin Fishfinder

by | Last updated: Nov 28, 2023

How to pick the right Garmin Fish Finder


l    Deciding on which marine electronics to go with can be a bit overwhelming. 

The most common questions we hear are…


Which Garmin fishfinder should I buy?

Simple Answer – the one with the biggest screen that will fit your needs and your budget.

Which Garmin fish finder is the best?

The best is the GPSMAP series but may not be what you really need.

Which Garmin fishfinders support Panoptix?

The ECHOMAP series & GPSMAP series.

Which Garmin fishfinder works with LiveScope?


What’s the best Garmin fishfinder for a Kayak?

The most popular is the Striker series but… mapping needs and power consumption are most important here.

What is the best Garmin fishfinder for a jetski?

Here, we like the ECHOMAP UHD series.


Here is our Detailed Guide for choosing the Garmin Chartplotter Fishfinder that will do what you want, along with some specific tips to help you start narrowing down your search.


Let’s Dive in… 1,2,3


1 – Pick your Screen Size & Budget


The quickest way to narrow down your search for the right unit is by deciding first on the screen size and second on your budget.

These will be the first two items to decide on because… they will eliminate the largest number of models to consider.

Start with:

  • What is the biggest screen size that is really practical for your application?
  • Determine the biggest size screen you can fit on your boat.
  • Figure out what size screen you would be able reasonably be able to see the best.
  • Decide on a budget. I find that Screen Size, Features, and Sonar options will generally be the biggest factors that effect cost.


2 – Make a List Of Features


Put together a list of everything you want the unit to be able to do. Decide what features are required and what you can live without.

  • Determine what mapping you need for your area.
  • What sonar channels do you want like DownVü, SideVü,  UHD, and Panoptix?
  • If you plan on networking… then list all the items that will be added to the network, like an additional unit, radar,  autopilot,  trolling motor control,  digital switching,  and engine interfacing.
  • Do you plan on Radar? Striker and Echomap series do not support Radar. The GPSMAP series does.

Keep in mind that ECHOMAP units can network with each other but not with the GPSMAP series, and GPSMAPs can connect with each other but not to ECHOMAPs.

Be sure to consider any future items you might want to add to be sure they will be compatible.


3 – Compare & Shop


Now that we have a good idea of what will fit,  what our budget is, and what we want the unit to do, we’re in a good position to start shopping and comparing.

Garmin Striker Plus Series


“Fishfinder with Built-In GPS”


Choosing the Best Striker Fishfinder

l   First, in the GOOD category, we have the Striker Series which has four sizes to choose from… 4″, “5,  7″ &  9” and have easy-to-use keypad controls.


An excellent fishfinder with a built-in GPS, the Striker family is perfect for single station installations. The Striker series is also considered an excellent Garmin fish finder for kayaks because of the low power consumption.

Keep in mind though, it’s not a Chartplotter. There is no mapping and you cannot add mapping or charts. If you need mapping then move up to the ECHOMAP series.

Although this series does not have mapping, Garmin added a premium feature (usually included with their upper-end models) called Quickdraw Contours.

Quickdraw Contours allows us to create 1′ custom fishing contours for any body of water. It’s like creating your own chart of the area with custom depth shading.


Garmin Sonar Mapping - Garmin Quickdraw Contours


There is enough internal storage for up to 2 Million acres of on-the-water contour maps and 5000 waypoints.

You also have the ability to record and save up to 50 tracks. You can also create up to 100 routes.

Built-in WiFi for access to ActiveCaptain for software updates, waypoint transfers, smart notifications and access to the Garmin QuickDraw community is available on the 7″ and 9″ models.

The entire Striker Plus line comes boxed with a transducer and a trolling motor mount to make installation simple and quick.

Echomap UHD Series - Choose the Right Garmin FishFinder

There are 3 UHD sizes and one small 4″ Plus version specifically designed for kayaks with multiple sonar and mapping options.

The UHD stands for Ultra High Definition. UHD  scanning sonar redefines scanning sonar and is what this family is built around. 


TIP: Garmin offers several versions across each family. How you know what the unit will do is by looking at the numbers on the unit.


The first number represents the size of the screen, the second number represents the mapping option.


Example: 93, the first number is a 9 so we know it’s a 9″ screen. The 73 is a 7″ inch screen, etc.


The 2nd number determine what mapping is built-in. So…a 3 it would have inland maps built-in and a 4  would have coastal maps built-in.


The 93 would have your inland lakes maps; that means it comes with 17,000 Lakes built-in 13,000 at 1′ contours.


The 94 would have your coastal maps built-in. That would give you the Coast to about 50 to 60 miles offshore.


Unfortunately for offshore Florida, it does not include the Bahamas but it does include the Great Lakes.





UHD gives you the ability to see everything below and off to the sides in amazingly sharp, crisp detail.

This makes it easy to scout a fishing area quickly because you can see everything in a larger area the first time with crystal clear images.

UHD sonar can be shared seamlessly across multiple networked ECHOMAP units.

This family also supports Panoptix real-time Sonar



Common Question: If I want to fish freshwater inland and saltwater offshore, do I need to have two units on my boat?


The answer is no.


If you have an inland map unit and you want the offshore maps or vice versa you have the option to buy the maps and put the SD card in the unit or download them via an ActiveCaptain account.


An EXCELLENT list of features 

  • Easy to use keypad control – 4″|6″
  • Touchscreen with key-assist – 7″|9″
  • Bright, sunlight-readable displays.
  • Quick-release bail mount for fast and easy mobility.
  • 6″ Can share waypoints and routes with ECHOMAP PLUS, UHD, or Striker models.
  • 7″ | 9″ Share waypoints, routes, and Sonar with other ECHOMAP Plus UHD and Ultras models.
  • NMEA 2000 interface with FUSHION-Link audio system, sensors, and engine data, and autopilot.
  • Built-in WiFi for pairing with free ActiveCaptain app for access to OneChart to purchase and download new charts, smart notifications, software updates and access to the Garmin Quickdraw Community data.



Powerful Built-In Sonar

  • NEW Ultra-High Definition Scanning Sonar
  • 6″|7″ CV models include CHIRP Traditional and Ultra-High Definition ClearVu
  • 7″|9″ SV models include CHIRP Traditional and Ultra-High Definition ClearVu and SideVu
  • 7″|9″ Supports Panoptix and Panoptix LiveScope System
  • Will share sonar with other ECHOMAP units




“10” & 12″ Chartplotters with Full Mapping, UHD & Livescope”

Echomap Ultra Series - Choosing Right Garmin FishFinder

The ECHOMAP Ultra models are 10″|12″ Chartplotters with built-in UHD. The 106/126 models come preloaded with both BlueChart g3 and LakeVu g3 Mapping.

They have larger screens than the UHDs and the sonar has a slightly stronger power output @ 600 Watts.

There are 4 models to choose from, with and without charts.

These units are available with or without transducers.  Options include the older GT54 or the newer GT56  transducer which offers somewhat better image quality.


Feature List

  • IPS displays with wide viewing angles.
  • Super Bright 1200 nits Screen.
  • Touchscreen with key-assist Controls
  • Built-in Cartography:
    • BlueChart g3 charts that cover the coastal U.S.
    • US LakeVu g3 maps that cover 17,000 total lakes, 13,000 with 1′ contours.
    • Built-in Auto guidance.
  • Networkable via Ethernet for Sonar and User Data sharing.
  • NMEA 2000, WiFi for ActiveCaptain app.


The ECHOMAP Ultra units are my favorite from a feature-cost standpoint. The sonar is excellent and the g3 mapping coverage is very good.

The only downside is that the chart coverage does not include any of the Bahamas. I’m on the east coast of Florida so that is kind of a bummer.



The ECHOMAP Plus, UHD & Ultra will not support radar and are not weather capable.

ECHOMAP units will only talk with other ECHOMAP units.

So if you want to share a sonar or mapping the ECHOMAP has to be paired up with another ECHOMAP unit.

They will not network with the GPSMAP series.


Tip: Another point to remember. If you have or intend on using ECHOMAP Ultra, that has both inland and coastal mapping and you want to pair it up to another ECHOMAP unit, save some money and get one without mapping and share from the Ultra.


If you buy an ECHOMAP 93 or 94, 73 or 74 with internal mapping you cannot share mapping with that ECHOMAP Ultra.
