### 4/5 — Works pretty well for the price

*2020-06-21*

It’s advertised to cast out away from your boat. We drag it as we troll in our small bass boat. Gives accurate depth and fish alarms. 

Seems to work right up to the point where the battery gets low. Can use it for at least 2 long day trips on the lake before recharging.
