1. 5/5Great instrument.

   Still learning how best to use this, but I’m enjoying at least knowing the depth and structure that I’m fishing. Having never had a sonar (or a boat!), I’m not aware of all the limitations, and it seems to work well for me as a shore fisherman. I know now where some deeper spots are that I can cast to - I find that I can only cast the sensor about as far as I can cast. It loses connection sometimes, but I think that if it stops for a more lent, it reconnects. The first couple of times I went out I dedicated a rod to it, but lately I just carry it in my shirt pocket. It’s light enough. I use 10-pound test, and it seems secure. It’s sort of a trick to cast it far if you’re not used to that much weight. I probably get about 75-80 feet. Fun product, thanks.

2. 3/5Not worth the price

   For $200 it’s not worth the price. It does not work under 3-4ft of water. Connectivity to phone is choppy at times, especially when you’re in an area of poor phone reception. It does not map nor save depth charts for you even after you scan a lake. You can see the depth as you’re boating around, but it doesn’t save nor add it to the maps on the app. The fish detection does appear accurate at times as I’ve caught a few fish when it says there are fish. The app features are very basic and not much options are available to switch between. The ball itself is way too heavy to cast unless you have a heavy rated rod with very strong line. This now requires you to carry 1 additional rod when you’re shore fishing. Battery life is very good, but your phone battery will drain quickly because it needs to be on consistently with max brightness in order to see it while you’re outdoor. In conclusion, for half the price it’s decent, but I wouldn’t buy it for full price. I bought mine for 32% off and still decided to returned it.

3. 1/5Dreadful

   Want to risk a private waterway’s privacy? Create an account and boat/gps scan it. Anyone will then be able to view its location with your depersonalized data. So sure, it’s not your exact scan, but the location is given away…I even see a dirt access road traced out; which is insanely weird, because it was named… along with the body of water (both of which are nameless on any other map you could possibly find). Someone created bogus information... And apparently, you need to “own” the land to have blue pin removed from global maps… I need to text owner to inform them their property is at risk. Essentially a scheme to give away locations to all the grubs who pay, or scan their way into Premium. Another thing is; nowhere do they mention guest mode keeps your scans off global maps, I found that in here as a response to someone else’s review. Never making an account would be your best bet if you happen to have a honey hole. All I can really do is chuckle though, most people would be fooled by the fish in the spot I scanned. They know who’s boss.

4. 3/5Awesome app, questionable privacy policy

   As far as I can tell, the app and the sonar device are of excellent quality and utility. Not too long ago, functionality like this would have cost way more. However, it appears that all of the user’s bathymetry data are automatically uploaded to the company who catalogs it, anonymizes it, and combines it with other users’ data to offer their premium service (however else they might use it is unclear). The privacy policy is vague about who actually owns the copyright to the bathymetry data that the user collects with the device that you have paid for. The web site FAQ does state that you can request to have removed any bathymetry data from a private lake but ONLY if you provide evidence that you own the lake! So basically, you are paying for the privilege of collecting data for them to market as they wish. I don’t mind this as a business model, but I wish they would be explicit so that all users know what they are actually buying into. The privacy policy or terms of use really ought to say in plain language: “You agree to turn over all of your bathymetry data to the company who can sell and market it however they choose.” Even better would be if they’d offer the user the ability to opt out of automatically turning over the user’s own data to the company.

5. 4/5MIXED

   I like the battery life on newest versions. I like when working properly finesse fishing on narrow scope at 100% sensitivity very accurate when understanding how device reads. When connecting it with deeper arm you have to turn the device backwards to make it forward facing. Behind the screws where it states deeper chirp2 is actually the front when in water so turning backwards enables you to see you bait on flasher and sonar. Dislikes…the disconnection when I’m in boat mode with setting very narrow and precise. I had device sent back and repaired but still does it just not as frequently. How it reads backwards and offline maps that don’t download and can’t utilize paying for premium membership is very frustrating.
