Summary: Love to use this. We use this in Crowley Lake, California. We have mounted it to PVC pipe to allow us to mount on a sturdy extendable pole from Home Depot. We then wired it to a cigarette adapter. This allows us to easily take on rental boats along with a reliable power source whether it is on the console of boat or battery charging pack for car. Very reliable readings, but keep in mind, just because you see them, doesn't mean that you will catch them. Tight lines!
Summary: Installed the transducer on my trolling motor with the included trolling motor mount and it is just what I needed to know the water depth while trolling. I like how the depthfinder can tilt and swivel to give you the best view. I ended up buying a metal bracket to hold the transducer to the trolling motor instead of using the included plastic bracket.
Summary: I bought this product to use off the bow of my boat to basically show the depth and see structure directly under the front of the boat for Crappie fishing and throwing my cast net. I have a side imaging unit mounted on the center console so this product works great for the purpose I wanted it for. When I was on the Ohio River by the dam, I was checking both my expensive Humminbird Side Imaging Unit and this unit to compare what it would show.
Summary: This is a GREAT, basic depth/fish finder. Installation was a snap. Power was supplied at the bow from the nav light's constant hot wire & ground. I chose to mount the transducer to my trolling motor, and it made for a very clean install. Perfect accessory at a very fair price!!
Summary: You can't beat this thing for a plain Depth Sounder. I just needed depth readings, and this fish finder is less expensive than the cheapest $99 depth only instruments. I'm even shooting the transom mount transducer through my hull, epoxiexd down. Works very well, Garmin simply rocks.
Summary: I'm not able to fish very often so I didn't want to spend a lot of money on a fishfinder so I purchased this unit. I attached the transponder to my bow mounted trolling motor and attached the unit to a flat board so I could move it around the boat. I did have to purchase a couple of wiring ring connectors to attach the wires to my trolling motor battery. The accuracy of the unit was fantastic and the screen was very easy to use. I'm purchasing another one for my pontoon!
Summary: I have 2 Garmin and 1 Humminbird fishfinder and/or Chartplotters. The Garmin's out rank the other brands on both the lower end and the top end. This little guy does just what it is supposed to and is easy to read. My only complaint is the power and sounder connectors in the back could be improved I worry they will wear out with time but for what the unit cost if it lasts 3-5 years I will be happy.
Summary: I am perfectly happy with my purchase of the Garmin Echo 100 Fishfinder. I am impressed at everything about it - the ease of installation, the clarity of the display, and the way it works. It is quick and follows my boat until at least 25 mph before losing lock on the bottom. I would guess that anybody who could only use the unit while stopped or just barely moving probably didn't install the transducer correctly.
