When looking for a speargun, you should first decide what type of gun you are looking for; either pneumatic or a banded gun. You then should decide on what your spending limit is.  Then you need to determine what size gun you are looking for. Here is my opinion on what guns you should consider in lower spending limits to higher spending limits and what size gun you are going to want to look at depending on what you want to use it for....

For a low budget, I would look at JBL's line of spearguns.  They are not bad guns and are sure worth the money.  I had a JBL for about 6 years and it still worked like new when I decided to sell it.  They are very sturdy guns and definetly the "most performance per dollar" gun.

For a middle budget, I would look at Rob Allen's and AB Biller's line of spearguns.  Rob Allen Spearguns are made in Australia and have the european setup on them.  They also have a closed muzzle on them and are another "most performance per dollar" gun.  They shoot very accurately and very hard.  AB Biller makes very nice polished wood and aluminum guns. They also shoot very accurately but not as hard as the Rob Allen's. I also have owned an AB Biller and liked it very much.

For a higher budget, you may want to consider Riffe and Daryl Wong guns. They are very expensive and very good. Riffe guns are made in California and now come in either european style, standard, or mid-handle guns. They are very accurate and shoot incredibly hard. Personally, I have a Riffe and am impressed beyond belief at its accuracy and durability. Daryl Wong guns are the most exclusive guns that I know about. Each one is hand made by Daryl Wong himself. They are manufactured in Hawaii and are incredibly manuverable in the water (extremely heavy out of the water.. I have yet to figure out how that works lol) and shoot extremely hard.

For reef and wreck spearfishing, I would recommend using a gun somewhere under 52 or so inches.  I have a 48 inch gun that I use for the reef and it works just fine.  Anything under 52 will probably be jsut fine but I wouldnt go any higher than that because it may be a little too big and hard to manuver.

For blue water spearfishing, I would recommend using a gun somewhere over 53 inches, but preferably around 56 or higher with 3 or more bands so that you will have the necessary power to shoot a fish moving incredibly fast at a distance.

I hope this guide helps all of you and if you ever have any questions, feel free to drop me a message and I will answer it as soon as I can.
