Clunky Nav Tool Rugged Enough, but Obtuse Maps Don'...


Our reaction on opening the box: Ew! But like a pug, the iFinder is so ugly, it's almost cute. Unfortunately, the performance is less lovable. Proprietary

High-contrast, multi-colored screen. Survived 5- and 10-foot drops, and even repeated dunkings

FreedomMaps deny you the freedom of detail; we have never seen a more half-baked topo maps. Bulky and inconvenient to carry. Device alerts you to marked waypoints with shrill, panic-inducing alarms

Lowrance iFinder Pro


The Lowrance iFinder Plus impressed us when we first reviewed it in December 2002, and the new Pro model is no slouch either.

Works well


We have used this unit cruising the Caribbean for the past year and have been very pleased with it. Great to have in the cockpit or in your pocket as you motor into an anchorage. Some of the functions are not as intuitive to use as I would like. It is...

Lowrance H2O C, May 1,2007


After doing some online research and talking to owners of the H20 C model, I decided to try one myself. So far it has been very user friendly, and with the addition of an internal map, it is even more accurate. This unit is good as a main unit on a...
