I stupidly forgot to order an extra charger clip for my Deep6 excursion, and I like to have spares of things like that. Unfortunately shipping is expensive to (and within) Canada, so I'm wondering if I can find a cheaper option. The 4 pin clip used by the Garmin _looks_ similar, but I don't if they are physically or electrically compatible. Does anyone happen to know? Is this some little known industry standard, or just coincidence that the clips look somewhat similar?
