The Community of Disc Golfers and About All Things Disc Golf
From My understanding you can use 150 class discs in PDGA sanctioned events. The only weight limits I could find were discs were not to exceed 200 grams. All the 150 class discs I have purchased have had a PDGA approved sticker on them and are in the list of PDGA Approved discs. But if you have a question if it is legal just ask the director of the tournament
GUIDELINES & PROCEDURES FOR MANUFACTURERS
TO CERTIFY THAT EQUIPMENT COMPLIES WITH
PDGA TECHNICAL STANDARDS
Hi-Tech is the designation given to all discs submitted and approved for PDGA competition. Unless
otherwise specified or restricted by the tournament director, all discs on the PDGA Approved list may be
used in regular PDGA competitions. Hi-Tech approved discs must:
(1) have a circular, saucer-like configuration, with a flight plate unbroken by perforations and an
underside inner rim depth that is between 5 and 12 percent of the outside disc diameter. The flight plate
is defined as the upper (or dorsal) section of the disc, which is delineated by the points where the inner
rim depth is measured. The saucer-like configuration requires a significant degree of asymmetry
between the upper and lower sections, resulting in distinct top and bottom sides of the disc;
(2) be made of solid, non-magnetic plastic material, without any inflatable components;
(3) not be less than 21 cm in outside disc diameter, nor exceed 30 cm in outside disc diameter;
(4) not exceed 8.3 g per cm of outside disc diameter;
(5) not exceed a maximum weight of 200 g;
Sorry, you are completely off.
All discs must be PDGA approved for sanctioned tournaments. For unsanctioned tournaments, they set their own rules but usually follow most PDGA rules.
There is no minimum weight for discs but there are maximum weights, set by PDGA technical standards based on the diameter of the disc (so the wider the disc the heavier it can be).
Tournaments, even sanctioned events, can make more restrictive rules under X Tier guidelines. So a tournament could ban all men (or Pros or yellow socks) or require glow-in-the-dark discs or even require 150 class discs. I'm not sure there are any 150 class tournaments being held in the U.S.. They existed for a while then faded away, evidently migrating to Japan.
'Evidently migrating to Japan', such as myself. 150 class is my favorite gane. This year they have added two more '150 Open' tournies to the list in Japan.When is Discraft going to sponser amajor here in Japan? Come on Mark, let7s get it together. We need Discraft in Japan! Everything thatgets put out in 150 sells here.
