New technology is always slow to travel to my part of Clare so I dont know how new these Gemini Splashdows are.
They are a lead with a built in baitclip which guarantees not to release the baited hook during the cast and then guarentees it will be released on impact.
The lead body itself has moulded flutes which drive water up against the plastic washer and pushes a rather complicated looking locking system.
When I first clipped a pennel mounted sandeel into the lead I noticed how tight a 4/0 hook fitted into the clip and how the head of the sandeel appeared to be obstructing the washer system.

Where the lead proved itself was on the first cast which was into near headwind, the close-coupling of bait to lead made it very streamline and I was able to deliver a sandeel a good diastance. during the session it never came unclipped during the cast and was released when I retrieved it.
Two things I can see that could be a problem: Firstly on a cold night numb fingers might struggle to insert the hook into the fiddley bait clip and secondly as I was given this lead I have no idea what they will cost here. A five ounce retails at around £2.60 in the Uk. If they were much dearer than the Breakaway impact leads that have serve me well for years I dont think I would fork out for them, but for those who require small baits, nicely presented at distance Gemini Splashdowns could be the purfect choice.
If you have tried them let me know what you think
