consider this.....
if you have a smart phone. Navionics has an App for $20
with every lake in Canada. Its very accurate and I use mine
with my depth finder to find drop offs etc. It also records tracks
and has a speed indicator etc.
it may not be exactly what your looking for but......
i cant think of what Ive spent $20 bucks on that I have used
more.
fish on Garth !!!
fish on Wayne !!!
