I still remember what seems like ages ago, my first and only JBL magnum-something, surprised and disappointed when I found out it would sink.. Probably my first ever speargun mod, removing the handle and muzzle and stuffing the pipe with Styrofoam as deep as it would go. Then after realizing it still wouldn't float, going home and teasing a somewhat inflated condom into the handle. Making a trip to the moonlit beach to test one final time. Yes that last bit did make the JBL float. But in those days I didn't foresee water pressure compressing my improvised "bladder". It didn't matter much anyways as I wasn't diving deeper than 15'. Look at me now, still stuffing pipes to make spearguns float. At least they're carbon pipes
LMAO! I gave up on the explorer i had after one dive. neat idea with the condom:laughing3:
