weight belt help

[spearfisher1]

Hi, im 14 years old and I have been spearfishing for almost 2 years now and use a polespear. I am thinking about getting a wieght belt because its hard for me to stay underwater for a long time without trying to kick back down. I am about 130 pounds and I mostly dive in around 6-20 feet of water (depends where the fish are). And im wondering about how much weight i should get. And I was also wondering, since I might get a speargun, what size of a speargun should I get? I was thinking about a 60 or 75 cm because the fish dont get that big but once in a while you'll find a big one but I dont know what size. Thanks alot.

spearfisher, the amount of weight will depend on the sort of wetsuit you wear and the depth you go to, i am 160 pounds and wear 2 kilos on a 3mm wetsuit ( i go from 5-15, rarely down to 20m). if you are not wearing a wetsuit and just want to make it easier to go to 2oft and say there, try with one kilo if it doesnt do it try with 2. be careful though as you ned to be able to surface with extreme ease!!!!! ( you will b out of breath and surfacing should require minimum effort). Always dive with a buddy NEVER DIVE ALONE even in shallow depths.
As fo the guns, factors also to consider besids the size of fish is visibility, the worse it is the shorter the gun you will need. also the bottom type (caves etc...)I would recommend you start yourself off with a band euro gun 60cm-75cm, these are very good sizes, i am 30 years old,the visibility here is great and i have landed many fish with my small cressi sub 60.
good luck,

I am 76KG, i use 7Kilos of weights to go down easily,ofcourse with a wet suit on.other wise if you dont have a wetsuit put 2 kg one on every side...but first try it in shallow water maybe a pool will be great...never dive alone.
get a wetsuit and and your life will change...i am 26 and only 3 years ago i had one...and i really missed a lot in my life...in winter big fish r there visibility is amazing( in my country Lebanon).

good luck

Hi Spearfisher1,

Like Marwan suggested, it varies by individual and situation, quite a lot. For most spearing, you want to be neutral to slightly negative on the bottom. My guess is for you in 20 ft, no suit, 4 lbs(2 kg) would be about right.
If you are using a suit, you can estimate weighting by finding out how much weight will sink your suit in the bath tub. Adjust that amount for the depth you are diving(or want to be neutral at). For example, for 20 ft, the weight you need is: 20/33 x (weight needed at the surface) Add that amount to your "no suit" weights. When you try it in the ocean, it will probably require some adjustment to fit you exactly.
When you look for a weight belt, try to get a rubber one. It is worth paying extra for.
