Excellent value. But a few minor foibles
April 22, 2019
I fittbed this with the transducer siliconed inside my kayak hull. It’s working great now but there were a couple of frustrating issues initially both of which could be solved by a better instruction manual and which I think are the cause of most of the negative reviews on here.

Firstly the unit arrives in demo mode. After I had fitted mine it stayed in demo mode even on the water. I played with every setting but couldnt get it to work. I assumed I must have fitted the sensor with some air bubbles underneath and in frustration ripped it out. When I got home and did some googling i I discovered that in the settings mode thetab to turn off demo mode is at the bottom of the menu off the screen so you have to scroll below the bottom of the screen to find it- very frustrating,

Secondly the unit in auto alters the depth range automatically to fill the screen. The problem is that if you are paddling or motoring and causing surface disturbance and bubbles the unit thinks the surface chatter is the bottom and sets range to 10’. then it cant find the bottom and scrolls through 20’, 40’ etc before losing the bottom again and reverting to 10’. This is what is causing the series of vertical lines with short sections of meaningless display in between. The solution is to select custom mode from the menu ( which counterintuitively is selcted by oressing the on button!) and set the range manually to whatever is appropriate for the current depth. I suspect that more careful placement of the transducer might eliminate this problem in larger displacement boats.
  • Cheap
  • Works once you have managed to negotiate the settings menu
  • Poor instruction manual leads to needless problems and frustration.
  • Auto range setting is very sensitive to surface chatter

Doesn't Work!

I bought this product in May. It has never worked. Unit would turn on but once it was taken off of demo wouldn't work. Took it back to Basspro and they couldn't get it to work. They then gave me the number to call Lowrance for help. Waste of time, said their system was down and would call back. Never heard from them. Do not buy this product!

This product sucks. the boat anchor was a better than the fish finder was. a total waste of money and time to buy this product. Very unreliable it would never display the same screen twice even when I was anchored and not moving I would have to say the stars in the ratings would be in the negative if it would let me

Used it twice, now it will not come on
June 4, 2018
I bought this for a fishing boat I've just finished redoing. I used it twice for a total of 2-3 hours, now it won't even power on. Inline fuse is fine, showing 12.2v at plug. Not a happy customer.

I have been using my hook 2 4x for a month.
Simple to install and setup.
A little lite on instructions but let be honest, who reads the manual until there is a problem?
From all that I read I expected it to have a simple GPS in the system but it must be well hidden as I have yet to find it.
But again who cares I have a high grade GPS on the boat and don't need the one that I thought would be on the hook.

I can travel at 25 knots and still get great bottom readings and depth numbers on the display.

Tells lies

Had it a couple months. Depth of water isnt accurate at all. Showed .9m when it was less than knee deep. The sonar thing with the circle is something Lowrance should dump , have no idea what its meant to do as instructions on these units are very limited. Head unit has no adjustment in any direction. The unit shows fish when there are none at all.
