Solid Constrction with Good Interior Padding


from NY, NY, US

Purchased this for my dive light and accessories. I did a good job picking out the right size, but the pick and pluck foam (which I didn't see mentioned on their website) makes a custom fit easy. If you do make an error in cutting too much/many, I found aqua seal to do a nice job putting the "missing" foam back. I managed to fit a BigBlue 4500 cordless dive light, charger, goodman glove, extra battery and have room for another battery. All of those accessory items are very much on the large size for their respective category. Solid case which I believe is going to provide years of solid protection from the elements, water and the occasional trauma we tend to inflict on our gear from time to time. Highly recommend.
