Lowrance iFinder H2Oc GPS
We purchased the Lowrance iFinder H2Oc GPS with some Navionics maps on an SD memory card. We used new Lithium AA batteries with the unit.
Our purpose for purchasing the unit was for use in navigating waterways
between Minnesota and Ontario, specifically the Rainy Lake region.
The unit worked very well, and was very useful for navigating these rocky lakes, with many navigational hazards, such as numerous rock outcroppings, and hazards just below the surface of the lake.
The only problem we encountered was a long delay in downloading/processing map information, if you chose to zoom in/out of your current display. It sometimes took 10 seconds or more for the new screen to load, and if you are using this device as an aid, and travelling across the lake at 30 or 40 knots, the delay was a little unnerving at times, specifically if the lake has a lot of rock pile hazards. And yes, the software states you should not use this device for navigation, it is only an aid.
The batteries we started with lasted all week, and we used this unit extensively all week.
When you arrive at your destination, you need to remember to load the specific map you will use. For the Navionics maps, you will also need to
know the abbreviated file name for the area you want to view. The file names are not always obvious, so make sure you review the software to know what map to load, for the area you are using the GPS. This is a Navionics comment, so we did not add or detract from the GPS review score.
That issue aside, we would probably rate this item overall at a 4.5.
If you are heading to a large unknown lake, looking for navigation aids, and a depth chart, this is a great tool, and we doubt you will regret the purchase. If you are getting older, the screen is a little small, but it is hand-held, and small enough to put in your pocket or tacklebox.
Good luck
