What Exactly is RMS?
Here is the Webopedia explanation…
RMS is the process used to determine the average power output of the speakers over a long period of time. RMS is derived from an equation which produces the most mathematically accurate measure of a speaker’s power output. The RMS value is often seen listed as “watts RMS” on product packaging
Sonar Options
- Dual Beam Sonar
- 60 or 120 Degree ( Dual- Beam)
Transducer
Included are quick-release tilt mount and versatile transom-mount transducer makes installation a snap… Mount & Go, couldn’t be easier.
OK, what the heck is a Transducer..? Here you go.
The Transducer is considered the Sonar unit’s “antenna.” It changes electric energy from the transmitter to high-frequency sound, sort of like radio waves work. The sound wave from the transducer travels through the water and is returned back from any kind of object in the water.
Hope that helps in explaining what a transducer is.

In shallower water, a viewing angle of up to 120 degrees lets you see fish well beyond the sides of your boat.

Garmin echo 150 Cons
- Wow, I searched and really couldn’t find anyone that actually owned this Fishfinder to have anything bad to say except they wish it came with a Storage case.
Another great Fishfinder for cheap that has features of more expensive models. Some users commented is a great fish finder for a small 16ft. aluminum boat… Easy to see the display even in the sun
I know you can’t go wrong with this Fish finder from Garmin…Dual-Beam for single beam price…Highly recommended
