spearfishing Chrimbo present advice PLEASE!

[whippet]

:wave Hello, I have a spearfishing mad brother and wondered if anyone had any tips for a Christmas pres, he already has fairly new flippers and a new gun, I think he may need a better knife so if anyone coudl recommend a good one that woudl be great and any other useful gizmos or gadgets.

Also just had a look at the freediving course in Portsmouth on the site, only down the road so thought may try it out - has anyone been? is it good etc?
Thanks x

A Float with an Alpha Flag is good safe present, I am assuming he hasn't got one.
The Cressi-sub Killer is a lovely little knife and quite cheap.~£10
