We did our own with a can of spray foam and about 4 feet of that clear vinyl plastic tubing.
Take the caps off of the ends of the rim and handle on the net, secure the clear pastic tubing onto the spray nozzle of the foam can, insert the end of the clear pastic tubing all the way into the rim and start spraying the foam while retracting the plastic tubing out of the rim, and then do the same for the handle. I made sure that ours was full, so it did come out the ends for a bit before it finished expanding. Trimmed off the excess and dug out the cavity behind the push button for retracting, cleaned up excess with a little acetone, replaced the caps, done.
First time out with it, tied a rope to it
, and then threw it in the water,,,, it floated, pushed it under and up it came, works great!
We did ours after losing our first one on the first trip out, by the time we circled back to it, it sank out of sight, and in the wind and waves it was gone for good. Definately reccommend doing this, pretty cheap insurance, as nets are not cheap! (Even when you get a great deal at PNT
).
