Ride A Pet radars
All six cash tiers, what each one actually detects, the restock economy behind them, and the naming error that has spread across the whole niche.
The item is called the Eternal Radar, not the Ethereal Radar
The top tier is called the Eternal Radar. It targets the ethereal rarity band, which is where the confusion comes from, and the name Ethereal Radar has spread widely enough that it appears on one page of the very site whose other page correctly calls it the Eternal Radar and states that no Ethereal Radar exists. The same site uses both names for the same thirty million cash item.
This is a small error that costs nothing to make and makes a guide impossible to check, because a player searching for an Ethereal Radar will not find one and may conclude the ladder ends lower than it does. The band is ethereal. The item is Eternal.
The full ladder
Every cash radar is bought from the Gear Shop, which sits in the middle of the ranch area. The Robux radar is bought from the normal shop shelf and is not part of the Gear Shop list. The six tiers are the only radars bought with cash, and they form a single ladder where each rung targets one more rarity band than the one below it.
| Radar | Band it targets | Price | Step up | Stock | Eggs it detects |
|---|---|---|---|---|---|
| Advanced RadarS3 | Rare | 50 | baseline | x5, dropping to x4 within a cycle | Cracked Egg, Easter Egg, Stone Egg, Leaf Egg |
| Jewel RadarS3 | Epic | 3,000 | 60x | x3 | Mushroom Egg, Flower Egg, Slime Egg, Ice Egg |
| Royal RadarS3 | Legendary | 20,000 | 6.7x | x3 | Glass Egg, Golden Egg |
| Magic RadarS3 | Mythic | 300,000 | 15x | x2 | Crystal Egg, Skull Egg, Dominus Egg, Flaming Egg, Sinister Egg, Soul Egg |
| Angelic RadarS4 | Divine | 7,000,000 | 23x | sells out. Price is hidden while out of stock | Aurora Egg, Galaxy Egg |
| Eternal RadarS4 | Ethereal | 30,000,000 | 4.3x | sells out. Price is hidden while out of stock | Blackhole Egg, Cherub Egg |
The lower four prices are the best corroborated figures on this entire site. Two independent sources publish the same six tiers in the same order with identical prices for the first four, and they do not cite each other. The top two are graded lower because only one source publishes them, and the second source explains why it cannot: a tier that is out of stock hides its price.
The step column is calculated on this page by dividing each price by the one below it, and it corrects something the sources get wrong. One of them states that prices step by roughly sixty times per tier. That is true of the first step and only the first step. The real progression is sixty, then under seven, then fifteen, then twenty three, then under five.
The pattern is worth reading twice, because it inverts the usual intuition about upgrade chains. The biggest cliff is at the very bottom, where the second radar costs sixty times the first. The cheapest relative step is at the very top, where the best radar in the game costs only about four times the one below it. The last rung is the best value on the ladder, and almost nobody describes it that way.
How a radar actually works
- Buy it, then equip it from your inventory and click anywhere on screen to activate it.
- It points at the target egg for 5 minutes.
- Each cash radar is single use. After the 5 minutes it is gone from your inventory.
- It points at the best egg of its rarity band that is currently on the map. A Jewel Radar does not point at any epic egg, it points at the best one available at that moment.
The targeting rule is the part that changes how you play. A radar does not reveal every egg of its band, it points at the single best one available at that moment. So a radar is not a map of everything you could collect, it is an answer to the question of which one is worth collecting right now, and it is only as good as what happens to be live.
The single use and the five minute window then combine into a real cost. Buying a radar you cannot afford to replace is buying one that expires mid decision, which is why the right moment to move up a tier is when the price has already become trivial rather than when you have just barely saved for it.
What the extra money does not buy
The shop panels do not state a per-tier detection range, and no source publishes one. What changes between tiers is the price and the rarity band it targets. The only verbatim capability description found anywhere is on the Infinite Radar card, which says it detects the nearest egg.
A common assumption is that a more expensive radar sees further. Nothing corroborated supports that. What the money actually buys is the ability to target a rarer band, which is a different thing and a better one to be correct about.
This is the kind of assumption that quietly costs people money, because it is never written down and never contradicted. Somebody assumes a bigger radar means a bigger radius, spends thirty million cash on the assumption, and has no way to check it afterwards. The honest position is that the range is unknown, and that the band is what is documented.
The stock economy behind the ladder
Stock shrinks as the tiers go up. The Advanced Radar appears at five and is down to four within a cycle, Jewel and Royal sit at three, Magic at two, and the top two sell out entirely. Each Gear Shop panel carries a live countdown, seen in the game as New gear in 3m 10s, with a green Restock button beside it. When the cycle rolls over the game announces Restocked Gear Shop to the whole server.
Every tier has its own independent Auto-Buy toggle, which buys the item for you the moment stock refreshes. Turning it on for a tier is how you reliably get one of the scarce tiers without watching the shop.
Each tier offers x1, x3 and x10 purchase buttons plus a gift option. The x10 Advanced Radar bundle costs 500 cash, which puts it inside the first hour of play.
The ladder is not gated by cash alone. The scarce tiers are gated by attention, and the tiers above Magic are gated by both. Auto-Buy is the mechanism that converts cash into stock, and it is the reason the shop is worth visiting before you can comfortably afford the item you want.
The bottom of the ladder steps by roughly sixty times per tier, and the steps get steeper going up. The correct moment to buy a tier is when your passive income has already made its price trivial, not when you can just barely afford it. A radar you have to save for is a radar you cannot afford to replace.
The Infinite Radar, and why it is a different question
The two systems answer different questions. A cash radar is banded and single use, so it answers where is the best egg of this rarity right now. The Infinite Radar is unlimited but its published description names no band and says only that it finds the nearest egg, which reads as a general locator rather than a rarity tool.
| Property | Cash radars | Infinite Radar |
|---|---|---|
| Cost | 50 to 30,000,000 cash | 399 Robux |
| Uses | Single use, five minutes | Unlimited, zero cooldown |
| Stock | Limited per restock cycle, can show No Stock | Never depletes, never restocks |
| Published capability | Targets one named rarity band | “Detects the nearest egg. Unlimited use.” |
| Bought from | The Gear Shop in the ranch | The shop Robux shelf |
Whether the Infinite Radar honours the same rarity targeting as the cash radars is not stated anywhere. The descriptions are not the same, and this site does not assume they are. A player buying it specifically to hunt Ethereal eggs should know that the card does not promise that. That is a real gap rather than a technicality, because the cash ladder is explicit about banding and the pass card is not, and a player buying the pass to farm a specific rare egg is buying on an assumption the description does not confirm.
Four game passes were created on 9 August 2026: Infinite Radar, Auto Collect, Instant Hatch and Infinite Backpack. Three of them were removed from sale on 15 September 2026, four days before Update 1. Infinite Radar is the only one still on sale.
Which one you should actually buy
The ladder maps cleanly onto the thing you are trying to collect, so the answer is usually the cheapest tier whose band contains your target. Buying above your band wastes cash on eggs you were not hunting, and buying below it produces a radar that cannot see what you want at all.
Two cases are worth calling out because they are where the decision is not obvious. The first is the bottom rung: the ten pack at five hundred cash puts the Advanced Radar inside the first hour of play, which makes it the default first purchase and the one that pays for itself fastest. The second is the top rung, and it is the one this site has the strongest opinion about.
The Eternal Radar is the only cash item in the game aimed at the ethereal band, which means the Blackhole Egg and the Cherub Egg. Because the clock starts at pickup rather than at spawn, the six areas are not equally usable. Only an area you can reach and return from inside the window is realistically collectible, which turns the question from how fast you can search into how far from your plot you can afford to go. Between a carry window that short and six spawn areas spread across the map, the practical answer for a player who wants that egg is not a faster mount, it is the radar that tells you which of the six areas is live. Thirty million cash against a consumable that is single use sounds steep until you compare it to how many failed trips it replaces.
For a player who is going to hunt that band repeatedly rather than once, the Infinite Radar at 399 Robux is the same spend decision in a different currency, with the caveat above about its unpublished banding. Cash buys you the band. Robux buys you the repetition.
What that repetition costs in cash terms can be stated, because the shop publishes exactly one exchange rate between the currencies: the cash packs. At that rate the pass price buys 8 of the 49 Robux packs, roughly 800,000 cash, 2 Magic Radar uses, 40 Royal Radar uses, or 16,000 uses of the cheapest tier.
What is still not established about radars
- The exact price of the Angelic Radar and the Eternal Radar as a settled fact. Both are single source because both hide their price when out of stock.
- Any per-tier detection range. None is published, by the developer or by any source.
- The length of the Gear Shop restock cycle. A countdown is visible in game but the cycle length is not documented.
- Whether the Infinite Radar targets a rarity band the way the cash radars do, or simply locates the nearest egg of any band.
- The food stall's full item list beyond Grass, and what each remaining food grants.
- What the luck value actually changes, and what any luck step costs.
- How the reported luck gain of twenty fits a cycle worth nine.
Common questions
- What is the best radar in Ride A Pet?
- The Eternal Radar at 30 million cash is the top of the cash ladder and the only one that targets ethereal eggs, which are the Blackhole and Cherub Eggs. It is not better because it sees further, because no source says it does. It is better because it is the only tier pointed at that rarity band.
- Is it the Eternal Radar or the Ethereal Radar?
- Eternal. Ethereal is the rarity band it targets, not the name of the item, and the wrong name has spread far enough that one publisher uses both names on two different pages for the same thirty million cash item. Searching for an Ethereal Radar will not find one.
- Does a more expensive radar detect eggs from further away?
- Nothing corroborated says so. The shop panels publish no per-tier detection range, and the only capability description found anywhere in the game is on the Infinite Radar card. What changes as you pay more is the rarity band the radar is aimed at, which is a different thing from its range.
- How long does a radar last, and can I use it twice?
- It points at the target egg for five minutes and it is single use. After those five minutes it is gone from your inventory. That applies to every cash tier from the 50 cash Advanced upward, and it is the main reason the Infinite Radar game pass exists.
- Why can I never see the price of the top two radars?
- Because a tier that is out of stock hides its price behind a red No Stock label. The figure is only visible in the seconds after a Restocked Gear Shop announcement, which is also why one source publishes those two prices and another does not.
- How do I reliably buy the scarce radar tiers?
- Turn on that tier own Auto-Buy toggle. Every tier has an independent switch that buys the item the moment stock refreshes, which is the only way to get a tier that sits at two units or sells out entirely without watching the shop panel.
