You can get a drybag from Sealine which is completely clear, so you know exactly where everything is...never mind just the strip.
The are made by Cascade designs, in Ireland, but are available all over the place.
Also, contrary to popular belief, the good ole BDH container ISN'T fully water proof. It is recommended that you fit a piece of rubber band over the entrance (an offcut from an old innertube) to fully seal the lid. (After the lid is fitted)
Better still, save youself the expense of a BDH and use old plastic Helmans Mayonaise containers, they are seethrough too!! Couple this with the inner tube seal idea, and hey presto! Money saved, and you are recycling without any effort!
