Mnay of the H20’s had issues picking up sattelites but Lowrance did fix many of the issues.
I sent mine in and I have never had an issue since.
I would think that since it is new, it should bring $150.00 plus.
They are still a pretty good unit. If you have issues with the new one, could be spendy to get it repaired.
Power cords are also a big issue as they go bad pretty easy unless one never bends the cord. I would guess in another year, they will not be available at all.
Then, rechargeable batteries would work.
