In Fisch, the GPS is an in-game coordinate display. Buy it, equip it, and use the three numbers it shows—X, Y, and Z—to travel to a marked location such as a repaired Treasure Map chest. You can purchase the tool at the chair beside the pond in Moosewood or at the guard-post tower in Mushgrove Swamp. The current item listing records one price and one function for both locations; the practical choice is whichever destination is easier to reach from where your character already is.
This guide explains the pickup spots, the coordinate directions, a reliable way to follow a target without overshooting, and the complete Treasure Map workflow. Interface prompts can vary by device or game update, so treat an on-screen interaction key as a prompt to follow rather than a permanent universal control.
How do I get the GPS in Fisch?
Go to either of the two listed pickup points, interact with the GPS there, pay the in-game currency cost, and then equip or use the tool from your inventory. The current Fisch Wiki GPS entry lists the same item at both destinations and identifies it as a coordinate display rather than a real-world navigation device.
Moosewood: chair beside the pond
- Travel to Moosewood.
- Find the chair immediately beside the pond.
- Interact with the GPS at that spot and confirm the purchase.
- Equip the newly acquired tool, then activate it to display your position.
The chair is the most convenient option when your current route already passes through Moosewood. If the object is difficult to see, search around the pond’s edge rather than the main buildings; the listed location is the chair next to the water.
Mushgrove Swamp: guard-post tower
- Travel to Mushgrove Swamp.
- Look for the guard-post tower.
- Check the tower for the GPS interaction.
- Complete the purchase and equip the tool from your inventory.
Both destinations provide the same GPS, so Mushgrove is not a stronger version and does not unlock a different coordinate mode. Choose it when you are already in or near the swamp, or when reaching Moosewood would require a longer detour.
What does the GPS cost?
The current item page lists the purchase at 100 C$. That is an in-game Fisch price, not Robux or a real-world charge. The same listing was updated September 25, 2026; because the page is community-maintained, check the live interaction if a later game update changes a price or placement.
What if my interaction key is different?
An April 23, 2025 guide describes pressing E and confirming the 100 C$ purchase at Moosewood (Roblox Den’s older GPS guide). Roblox can show different prompts on keyboard, controller, or mobile, and the game’s interface can change between updates. Use the button prompt shown on your device; the important sequence is interact, confirm the purchase, and equip the tool.
What do the X, Y, and Z numbers mean?
The GPS reports three axes. X and Z describe horizontal movement across the map, while Y describes elevation. The direction notes on the GPS page define which way each value changes:
| Coordinate | Value increases when you travel | Value decreases when you travel | What it controls |
|---|---|---|---|
| X | West | East | Side-to-side position on the horizontal plane |
| Y | Upward | Downward | Elevation, such as climbing or descending |
| Z | South | North | Front-to-back position on the horizontal plane |
Do not treat a larger number as automatically “farther” in every direction. For X, a larger value means farther west; for Z, a larger value means farther south. Y is independent of those two axes and changes as your character rises or falls.
Why can a coordinate become negative?
A coordinate can be below zero when the game’s map origin lies on the opposite side of that axis. The sign itself is not an error. Compare your current number with the target: if the target X is higher, move west; if it is lower, move east. Apply the same comparison to Z using south for an increase and north for a decrease.
How do I follow coordinates without getting lost?
The most dependable method is to solve one axis at a time, checking the GPS after each short leg. This procedure is practical navigation guidance inferred from the axis mapping; it avoids trying to judge diagonal movement by eye.
- Record your starting position. Open the GPS and note your current X, Y, and Z. Keep the target values visible from the repaired map or another in-game reference.
- Compare X first. If your X is below the target X, travel west until the values are close. If your X is above the target, travel east. Pause periodically and read the GPS again.
- Match Z next. With X near the target, move south when your Z is too low and north when your Z is too high. Short, straight legs make it easier to see which movement changed the number.
- Adjust Y last. Once the horizontal values are close, climb, jump, descend, or otherwise change elevation until Y approaches the target. A chest can be above or below you even when X and Z look correct.
- Use small corrections. Stop before the numbers pass the target, then approach from the opposite direction if needed. Rechecking after each correction prevents a long detour caused by overshooting.
- Search the immediate area. Coordinates identify a position, not a highlighted path. When all three values are close, inspect nearby ground, platforms, shorelines, and vertical levels for the actual object.
Example of axis-by-axis movement
Suppose your GPS reads X 120, Y 8, Z −40 and a target reads X 150, Y 14, Z −10. The target X is higher, so move west; the target Z is also higher, so move south; and the target Y is higher, so finish by gaining elevation. You do not need to perform those movements in one diagonal sprint. Recheck after the west leg, then the south leg, then the climb, and stop when the three readings are close enough to search.
How close is close enough?
The available data does not establish a universal distance tolerance or a guaranteed chest radius, so do not assume that a particular numerical difference always opens an object. Use matching numbers as a way to reach the correct area, then look around the position and account for your character’s footing and elevation.
How do I use the GPS to find a Treasure Map chest?
A Treasure Map must be repaired before it supplies a chest location. The GPS then turns that location into a navigation task.
- Obtain a Treasure Map while fishing. Maps can appear through fishing activity, according to the Treasure Map entry.
- Take the map to Jack Marrow. Jack Marrow is at Forsaken Shores.
- Pay the repair fee. Repairing the map costs 250 C$. The unrepaired map does not provide the usable chest location described by the guide.
- Read the repaired map’s location. After repair, the map reveals the chest’s coordinates or location information.
- Open the GPS and compare readings. Use X, Z, and then Y to plan the route. The Treasure Chest guide describes using the GPS to follow the repaired map’s coordinates.
- Travel in measured legs. Correct horizontal axes first, adjust elevation, and recheck the display as you approach.
- Search and open the chest. When the readings place you at the target area, inspect the surrounding terrain and interact with the chest if it is visible.
The repair fee is separate from the GPS purchase. Plan for both costs if you do not already own the tool and have just obtained a map. The map’s repair step is also the point at which the chest destination becomes useful; carrying an unrepaired map to a coordinate target will not give you the same information.
What if the chest is not visible at the coordinates?
- Check Y before wandering horizontally. You may be directly above or below the chest while X and Z are already close.
- Re-read the signs. A target with a larger X requires westward movement, while a smaller X requires eastward movement. For Z, larger means south and smaller means north.
- Look around the arrival point. Coordinate readings guide you to an area; terrain, platforms, and sightlines can hide the object from the exact standing spot.
- Confirm the map was repaired. The repair at Forsaken Shores is what reveals the actionable chest location.
- Account for updates or interface changes. Community pages record the current documented behavior, but an updated live game can alter placement, prompts, or presentation.
Which GPS pickup location should I use?
There is no feature or price advantage between the two listed locations. Select the one that minimizes travel from your current position and fits your immediate route.
| Pickup point | Best when | What to look for | Trade-off |
|---|---|---|---|
| Moosewood | You are already in Moosewood or nearby | The chair beside the pond | Less convenient if your current objective is in or beyond Mushgrove |
| Mushgrove Swamp | You are exploring the swamp or approaching from that side | The guard-post tower | Less convenient if you would otherwise need to detour from Moosewood |
Both routes end with the same usable coordinate display. The choice is logistical, not a comparison of stats, capacity, range, or accuracy; none of those alternate specifications is established for the item.
What should I do if the GPS does not appear after buying it?
First check your inventory and equip the tool rather than expecting the numbers to remain on screen automatically. If the purchase interaction completed but the display is absent, activate the equipped item and look for its coordinate readout.
The purchase prompt never appears
- Move close to the chair or tower and try the interaction from different sides.
- Use the device-specific prompt shown by Roblox instead of assuming the keyboard key from an older guide.
- Confirm that you have enough C$ for the listed price before attempting to confirm.
- If the object or prompt is missing after a game update, rejoin the experience and check the current live placement.
The numbers look wrong for the direction I am traveling
Use the documented mapping rather than intuition: west raises X, east lowers X, south raises Z, north lowers Z, and upward movement raises Y. Take a short step, read the GPS, and use the observed change to confirm that you are applying the correct axis before committing to a long trip.
The GPS is equipped but hard to read
Stop moving and open the tool’s display again. Recording the three values in a note can help when a map gives a distant target. On a crowded screen, move away from visual effects or other menus so the coordinate text is easier to distinguish, then resume one-axis navigation.
Can I use the GPS for anything besides Treasure Maps?
Yes. The GPS is a general current-position readout, so any activity that gives you a coordinate target can benefit from the same X, Y, and Z method. The documented Treasure Map workflow is the clearest example, but the tool itself is not described as being locked to chests or consumed after one use.
Use it to record a position you want to revisit, communicate an area to another player, or retrace a route. Those are navigation applications of the coordinate display, not separate GPS features with their own documented settings.
What is known about the current GPS information?
The item and map pages cited here show an update date of September 25, 2026 and are community-maintained rather than official developer publications. That makes them useful references for the listed locations, costs, and coordinate directions while still leaving room for live-game changes.
For that reason, verify an exact button label, object placement, or visual layout in your current Roblox client. The durable parts of the method are to obtain the tool at one of the two listed locations, read all three axes, apply the documented direction changes, and recheck your values as you travel.
Quick checklist for a GPS trip
- Have enough C$ for the GPS, and for map repair if you are pursuing a Treasure Map.
- Reach the Moosewood pond chair or Mushgrove guard-post tower.
- Interact using the prompt shown on your device and equip the purchased tool.
- Write down current X, Y, and Z before setting out.
- Move west/east to correct X, then south/north to correct Z, then up/down to correct Y.
- Recheck after each leg and search the nearby terrain when the values are close.
- If the route fails, verify the map repair, axis signs, elevation, and current interface.
Frequently Asked Questions
Does the Fisch GPS use Robux?
The documented purchase is priced in C$, the game’s currency, rather than Robux. The listed GPS price is 100 C$, so a Robux purchase or physical Roblox product is not part of this acquisition method.
Can another player give me their GPS?
The documented method describes buying the tool at Moosewood or Mushgrove, not trading or transferring it. If a future update adds sharing, confirm that behavior in the live game because it is not established by the current item listing.
Why does my Treasure Map show no useful destination?
A map obtained while fishing must be taken to Jack Marrow at Forsaken Shores and repaired before its chest location becomes actionable. Until that repair step is completed, there is no repaired-map coordinate target to follow.
Do I need to keep the GPS open while traveling?
You only need to activate it whenever you want to read your current position; record the values, move a short distance, and check again. Keeping a note of the last reading can reduce menu switching on a long route.
