I won't use anything other than the Blacks Releases. I usually don't have any problems releasing them unless they are way below 100 feet. I run 15 lb weights. If you're running lighter weights, it may be the blowback changing the angle of the release making it harder to release. Also, it could be too much loading lifting the weight at an odd angle causing it to release harder (just guessing here).

I don't know why you would call it BS, it's says right there in the product name "NAVIONICS FISH N CHIP GREAT LAKES CF" - CF = Compact Flash. CF is not SD.

Right on the website http://www.navionics.com/MarineFeatures_FishNChip.asp it says:

"CF and MicroSD media cards are pre-programmed and ready to use with today's leading Navionics Gold compatible chartplotters…"

What more did you want them to do?

IF my input is correct, the abandoned tribal nets would be here, approximately 4 miles from shore:
