Deeper PRO Smart Sonar Fish Finder Bundle – Castable Wi-Fi Fish Finder with Smartphone Mount for Fishing Rod | Portable Depth Finder for Bank, Boat, Kayak, Ice Fishing | GPS Mapping & App Compatible

This is exactly what I was hoping it would be! Works great with my iPhone and is very responsive. No reason to spend 2-3x more on a flasher when this does more for less! Pretty fun to use to find good fishing spots and see when a fish is reacting to your bait. Battery lasts longer than my phone battery and works in negative temperatures just fine!

the instruction manual is rather vague. you have to sign up through the downloaded application in order to view the manual. Even that is not as clear as i would like, (I am a senior citizen with limited vision. i think so far, i like the product. what i think is a scam, there is no mention of there being a premium for this product to work in its best mode of operation. there is no off or on button. it must be in the water to make a connection to make adjustments.

Wow!!! I own 4 boat finders and two ice flashers and all I can say is wow. Its a powerhouse that fits in your pocket. I bought this to fish a local spot that doesn't allow boats but you need to find the deep holes. This and a depth map has allowed me to do that. You really should dedicate a rod of its own like a stiff surf rod to get it where you want cause its heavy. I have thrown it like a baseball but mostly keep it on a 2 piece 7 foot eel rod with braid. I can easily see this replacing a few boat units and maybe a ice flasher. I can't say enough good things. I also 3d printed a boat mount and really like it for my small boats and canoes.

Got the deeper pro. Have only used once somewhat satisfied. Maybe that will improve with time. Really question its water temp accuracy. Did a lot of reading and research before purchasing. For me, to many options coupled with horrible owners manual. You have to comb the net to figure out how to set up and what setup options are and what affect. Nice owners manual with setting explanations would be nice. As winter leaves will use more and perhaps my rating will go higher.

I love it, takes a little use to understand how it works. I yea it from the bank in neighborhood retention pond it has help snowing how and where the fish are schooling.
