was thinking about getting an L.E.D. flash light for my nightdives, but when i checked online, everyone is claiming to be the best which one should i get? i dont want something too expensive, but at the same time , i dont want a bad one as well and regret buying it.

the same goes for the spear gun, i know it depends on alot of factors , and im planning to do more reading about the speargun , but i might go for blue water , the visibility might be like 30ft +- , most likely i'll be going after fish that are less than 3 feet long or a little bit bigger, but not so big , im not a big guy, so i'd rather not shoot something that might be able to pull me down under, maybe some baracodas

i might as well use it for reef hunts , i heard some guns require a lot of strength just to prepaire it again for shooting
and some of them are compressed ones? i think some people told me that i should stay away from the compressed guns.

thanks in advance.
