Bathymetric charts are the underwater equivalent of topographic maps.
Each map is made using baltic birch and is stained (or painted) to create gorgeous layers.
The charts give you a completely new view of your favorite waterways.
100’s of lakes and different sizes are available for custom order. ($65 for 8.5X11 maps)
Mazinaw, Opeongo, Sharbot, Silver, Simcoe, Great Lakes, Rideau, Bennet, Bob's, Desert etc.
