This portable fish finder gives excellent temperature and depth readings and provides you with a very accurate depiction of the structure under,
My biggest challenge with this device is that the fish identification functionality isn’t very trustworthy. I had to pretty much rely on the device’s raw data to locate fish, which isn’t a big issue as the raw data is extremely accurate, but it’s frustrating to not be able to use the Signstek’s fish ID feature.
If you’re a beginner angler with no idea of where fish are likely to be by looking at topography, depth, bottom structure and temperature this device won’t do you much good. Even with a lot of tweaking of the settings, I was never able to fully get the fish ID to work 100% efficiently.
Plus, there are no real mounting options with this device. It comes with a neck strap, but if you were hoping to mount it to your boat you’re out of luck.
Conclusively, this unit is god for paddling around a lake, discovering the crannies and little nooks fish are likely to be hiding in and fit to be included in our honest review of the best cheap fish finders under $100.
- Display is 100% readable
- Bottom structure readings
- Temperature and depth is accurate
