as someone who enjoys fishing for relaxation and fitness, i was always guessing where the fish were, which got frustrating. this little device solved that by letting me check the water with my phone—no more wasted time or casts. it's been a game-changer for my trips to the lake, making everything more efficient and fun. i'd definitely recommend it to anyone who fishes regularly.
- Pros: i love how it connects to my phone without any fuss, making it super easy to see what's swimming below. it's tiny and light, so i can carry it anywhere without it being a bother, and the view it gives is really clear, helping me spot fish before i even cast.
- Cons: from what i feel, the battery could last a bit longer on a full charge, and sometimes the connection might drop if i move too far from my phone, but it's not a big deal for casual use.
