## Questions & Answers

**Q: What type of battery can I use??**
A: 12v, boat battery

**Q: Does this finder have gps**
A: Hello,
It does not have GPS, its only a sonar for fish finding and depth.

**Q: se puede conectar a una bateria de 12v**
A: I can read Spanish

**Q: Is the screen water proof?**
A: I’m sure it’s a resistant thing.  Like most all fishfinders.  Rain shouldn’t hurt it too bad but submersion would be an issue.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Finder
*by G***. on November 12, 2024*

Fast shipping accurate description good quality

### ⭐⭐⭐⭐ Fish and depth finder
*by H***Y on April 18, 2025*

For the money and what I use it for it's great. Used it in Canada on my rental boat. It will run about 4 full days on one 12 volt battery pack. Mostly just to see depth and what the bottom looks like.

### ⭐⭐⭐⭐⭐ Not to big not to small
*by C***Y on April 18, 2024*

I put this on my flat bottom to find holes for trotlines and limb lines worked out great big enough to read but small enough not to be in the way
